Determine the ‘falling number’ of the flour according to standard EN ISO 3093. If the ‘falling number’ is higher than 250, determine the malt flour addition required to bring it within the range 200 to 250, using a series of mixtures of the flour with increasing quantities of malt flour (point 4.5). If the ‘falling number’ is lower than 250, no malt flour is required.

7.3. Reactivation of active dry yeast U.K.

Adjust the temperature of the sugar solution (point 4.4) to 35 ± 1 °C. Pour one part by weight of the active dry yeast into four parts by weight of this tempered sugar solution. Do not stir. Swirl if necessary.

Allow to stand for 10 ± 1 minute, then stir until a homogeneous suspension is obtained. Use this suspension within 10 minutes.

7.4. Temperature adjustment of the flour and the dough liquid U.K.

The temperature of the flour and the water must be adjusted to give a dough temperature of 27 ± 1 °C after mixing.

7.5. Dough composition U.K.

Weigh, with a precision of 2 g, 10 y/3 g flour on as-is moisture basis (corresponding to 1 kg flour on a 14 % moisture basis), in which ‘y’ is the quantity of flour used in the farinograph test (see ICC Standard No 115/1).

Weigh, with a precision of 0,2 g, the quantity of malt flour necessary to bring the ‘falling number’ within the range 200 to 250 (point 7.2).

Weigh 430 ± 5 g sugar-salt-ascorbic acid solution (point 4.3) and add water to a total mass of (x – 9) 10 y/3 g, (see point 10.2) in which ‘x’ is the quantity of water used in the farinograph test (see ICC Standard No 115/1). This total mass (usually between 450 and 650 g) must be achieved with a precision of 1,5 g.

Weigh 90 ± 1 g yeast suspension (point 7.3).

Note the total mass of the dough (P), which is the sum of the masses of flour, sugar-salt-ascorbic acid solution plus water, yeast suspension and malt flour.

7.6. Mixing U.K.

Before starting, bring the mixer to a temperature of 27 ± 1 °C by use of a suitable quantity of tempered water.

Place the liquid dough ingredients in the mixer and place the flour plus malt flour on top.

Start the mixer (speed 1, 1 400 rev/min), and allow to run for 60 seconds. Twenty seconds after the start of mixing, turn the scraper attached to the lid of the mixing bowl two revolutions.

Measure the temperature of the dough. If it is outside the range 26 to 28 °C, discard the dough and mix a new one after adjustment of ingredient temperatures.

Note dough properties using one of the following terms:

• non-sticky and machinable, or

• sticky and non-machinable.

To be considered ‘non-sticky and machinable’ at the end of mixing, the dough should form a coherent mass which hardly adheres to the sides of the bowl and spindle of the mixer. It should be possible to collect the dough by hand and remove it from the mixing bowl in a single motion without noticeable loss.

7.7. Dividing and rounding U.K.

Weigh, with precision of 2 g, three pieces of dough according to the formula:

p

=

0,25 P, where:

p

=

mass of scaled dough piece,

P

=

total mass of dough.

Immediately round the pieces for 15 seconds in the moulder (point 5.10) and place them for 30 ± 2 minutes on the square plastic sheets (point 5.9), covered by the inverted plastic boxes (point 5.8) in the proving cabinet (point 5.7).

Do not use dusting flour.

7.8. Moulding U.K.

Bring the pieces of dough on the plastic sheets, covered by the inverted boxes, to the moulder (point 5.10), and re-round each piece for 15 seconds. Do not remove cover from a piece of dough until immediately before rounding. Note dough properties again, using one of the following terms:

(a)

non-sticky and machinable, or

(b)

sticky and non-machinable.

To be considered as ‘non-sticky and machinable’ the dough should adhere hardly, or not at all, to the sides of the chamber so that it can freely rotate around itself and form a regular ball during the operation of the machine. At the end of the operation the dough should not stick to the sides of the dough-moulding chamber when the lid of the chamber is raised.

8. Test report U.K.

The test report shall mention:

(a)

dough-handling properties at the end of mixing, and at moulding,

(b)

the ‘falling number’ of the flour without addition of malt flour,

(c)

any anomalies observed.

(d)

the method used,

(e)

all details required for the identification of the sample.

9. General remarks U.K.

9.1. The formula for the calculation of the quantity of dough liquid is based on the following considerations: U.K.

Addition of x ml water to the equivalent of 300 g flour at 14 % moisture produces the required consistency. As in the baking test 1 kg of flour (14 % moisture basis) is used, whereas x is based on 300 g of flour, for the baking test x divided by three and multiplied by 10 g of water is needed, so 10 x/3 g.

The 430 g sugar-salt-ascorbic acid solution contains 15 g salt and 15 g sugar. This 430 g solution is included in the dough liquid. So to add 10 x/3 g water to the dough, (10 x/3 + 30) g dough liquid composed of the 430 g sugar-salt-ascorbic acid solution and an additional quantity of water must be added.

Although part of the water added with the yeast suspension is absorbed by the yeast, this suspension also contains ‘free’ water. It is arbitrarily supposed that 90 g yeast suspension contains 60 g ‘free’ water. The quantity of the dough liquid must be corrected for this 60 g of ‘free’ water in the yeast suspension, so 10 x/3 plus 30 minus 60 g must finally be added. This can be rearranged as follows: (10 x/3 + 30) – 60 = 10 x/3 – 30 = (x/3 – 3) 10 = (x – 9) 10/3, the formula given in point 7.5. If, for example, a water addition x in the farinograph test was found of 165 ml, this value must be substituted in this formula, so to the 430 g sugar-salt-ascorbic acid solution water must be added to a total mass of:

(165 – 9) 10/3 = 156 × 10/3 = 520 g.

9.2. The method is not directly applicable to wheat. The procedure to be followed for characterising the baking properties of wheat is as follows: U.K.

Clean the wheat sample, and determine the moisture content of the cleaned wheat. If the moisture content is within the range 15,0 % to 16,0 %, do not temper the wheat. If the moisture content is outside this range, adjust the moisture content to 15,5 ± 0,5 %, at least three hours prior to milling.

Mill the wheat into flour using a Buehler laboratory mill MLU 202 or a Brabender Quadrumat Senior mill or similar equipment having the same characteristics.

Choose a milling procedure that yields a flour of minimum 72 % extraction, with an ash content of 0,50 to 0,60 % on dry matter basis.

Determine the ash content of the flour according to Annex II to Commission Regulation (EU) No 234/2010(3) and the moisture content according to this Regulation. Calculate the extraction rate by the equation:

E = (((100 – f) F)/(100 – w) W) × 100 %

where:

E

=

extraction rate,

f

=

moisture of the flour,

w

=

moisture content of the wheat,

F

=

mass of flour produced with moisture content f,

W

=

mass of wheat milled with moisture content w.

Note: Information concerning the ingredients and equipment to be used is published in Document T/77,300 of 31 March 1977 from the Instituut voor Graan, Meel en Brood, TNO — Postbus 15, Wageningen, Netherlands. U.K.

Three representative samples, each weighing a minimum of one kilogram, shall be collected. One each shall go to:

(a)

the operator;

(b)

the storage place where takeover is to take place;

(c)

the paying agency.

To make up the representative samples, the number of individual samples to be taken shall be obtained by dividing the quantity of the lot by 10 tonnes. Each individual sample shall weigh the same. The representative samples shall be made up of the sum of the individual samples, divided by three.

The quality requirements shall be verified using the representative sample intended for the store where takeover is to take place.

2. Representative samples shall be taken of each part-delivery (by lorry, barge, railway wagon) under the conditions laid down in point 1. U.K.

Before its entry into the intervention store the examination of each part-delivery can be restricted to a check of the moisture content and impurity level and verification that no live insects are present. However, if it later becomes apparent when the check is finalised that a part-delivery does not satisfy the minimum quality requirements, the concerned quantity shall be refused for takeover. If the paying agency is able to check all the minimum quality requirements for each part-delivery before it enters the store, it shall refuse takeover of any part-delivery that fails to satisfy these requirements.

3. The control of the radioactivity level is performed only if the situation so requires and for a limited period. U.K.

4. In cases of dispute, the paying agency shall have the necessary tests on the paddy rice in question carried out again, the cost being met by the losing party. U.K.

A new analysis is performed by a laboratory recognised by the paying agency on the basis of a new representative sample made up, in equal parts, by samples preserved by the operator and by the paying agency. In cases where there were part-deliveries of the lot tendered, the result is given by the weighted average of the results of analyses of new representative samples taken for each of the part-deliveries.

PART II U.K. Prices increases and reductions

1. The price adjustments provided for in Article 26(1) shall be expressed in euro per tonne and apply to tenders for intervention by multiplying the price referred to in that Article by the sum of the established percentage increases in Tables I, II and III of this Part. U.K.

using a clean, dry butter trier or similar suitable instrument, extract a core of butter of at least 30 g and place in a sample container. The composite sample must then be sealed and forwarded to the laboratory for analysis;

(b)

at the laboratory the composite sample is to be warmed in the original unopened container to 30 °C and shaken frequently until a homogeneous fluid emulsion free of unsoftened pieces is obtained. The container should be one half to two thirds full.

Two samples per year per producer offering butter for intervention must be analysed for non-milk fat.

2. Sensory evaluation U.K.

Quantity of butter(kg)	Minimum number of samples
1 000 ≤ 5 000	2
> 5 000 ≤ 25 000	3
> 25 000	3 + 1 per 25 000 kg or part thereof

Following a trial storage period of 30 days, samples are to be taken randomly from different parts of each lot between the 30th and the 45th day following delivery of the butter and graded.

[F3 Each sample shall be assessed individually. No resampling or re-evaluation is allowed.]

3. Guidelines to be followed where samples show defects U.K.

(a) chemical and microbiological analysis: U.K.

(i)

where individual samples are analysed, one sample showing a single defect out of five to 10 samples or two samples each showing a single defect out of 11 to 15 samples may be allowed. Where a sample shows a defect, two new samples must be taken from either side of the sample showing the defect and checked for the parameter in question. Where neither sample meets the specification, the quantity of butter between the original two samples on either side of the sample showing the defect must be rejected from the quantity offered.

Quantity to be rejected where the new sample shows a defect:

(ii)

where composite samples are analysed and found to show defects in respect of one parameter, the quantity represented by the composite sample concerned is to be rejected from the quantity offered. The quantity represented by one composite sample may be determined by subdividing the quantity before samples are taken randomly from each part thereof;

(b) sensory evaluation: where a sample fails the sensory evaluation, the quantity of butter between two neighbouring samples on either side of the sample failing is to be rejected from the quantity of the lot, U.K.

(c) where samples show a sensory defect and either a chemical or a microbiological defect, the whole quantity is to be rejected. U.K.

8. PROCEDURE U.K.

8.1. Preparation of the test sample U.K.

Transfer the milk powder into a container with a capacity of about twice the volume of the powder, fitted with an airtight lid. Close the container immediately. Mix the milk powder well by means of repeated inversion of the container.

8.2. Test portion U.K.

Weight 2,000 ± 0,001 g of test sample into a centrifuge tube (6.2) or a suitable stoppered flask (50 ml).

8.3. Removal of fat and proteins U.K.

8.3.1. Add 20,0 ml of warm water (50 °C) to the test portion. Dissolve the powder by shaking for five minutes using a mechanical shaker (6.3). Place the tube into the water bath (6.10) and allow to equilibrate to 25 °C U.K.

8.3.2. Add 10,0 ml of the trichloroacetic acid solution (5.1) of ca. 25 °C in two minutes, while stirring vigorously with the aid of the magnetic stirrer (6.4). Place the tube in a water bath (6.10) and leave for 60 minutes U.K.

Note 2. Rinse the columns with water during each interruption. Never leave the eluent solution in them (5.2). U.K.

Prior to any interruption of more than 24 hours, rinse the columns with water then wash them with solution (5.3) for at least three hours at a flow rate of 0,2 ml per minute.

8.4.2. The results of chromatographic analysis of the test sample [E] are obtained in the form of chromatogram in which each peak is identified by its retention time RT as follows: U.K.

Peak II:	The second peak of the chromatogram having an RT of about 12,5 minutes.
Peak III:	The third peak of the chromatogram, corresponding to the CMP, having an RT of 15,5 minutes.

The choice of the column(s) can affect the retention times of the individual peaks considerably.

The integrator (6.11.6) automatically calculates the area A of each peak:

A II :	area of peak II,
A III :	area of peak III,

It is essential to examine the appearance of each chromatogram prior to quantitative interpretation, in order to detect any abnormalities due either to malfunctioning of the apparatus or the columns, or to the origin and nature of the sample analysed.

If in doubt, repeat the analysis.

8.5. Calibration U.K.

8.5.1. Apply exactly the procedure described from point 8.2 to point 8.4.2 to the standard samples (5.4) U.K.

Use freshly prepared solutions, because CMP degrade in an 8 % trichloroacetic environment. The loss is estimated at 0,2 % per hour at 30 °C.

8.5.2. Prior to chromatographic determination of the samples, condition the columns by repeatedly injecting the standard sample (5.4.2) in solution (8.5.1) until the area and retention time of the peak corresponding to the CMP are constant U.K.

9. EXPRESSION OF RESULTS U.K.

9.1. Method of calculation and formulae U.K.

9.1.1. Calculation of the response factors R: U.K.

R II = 100/(A II [0])

where:

=

the response factors of peaks II,

• S _II [E] = R _II × A _II [E]

• S _III [E] = R _III × A _III [E]

• S _IV [E] = R _IV × A _IV [E]

where:

=

the areas of peaks II and III respectively in the sample [E] obtained in 8.4.2,

R _II , R _III

=

the response factors calculated in 9.1.1.

9.1.3. Calculation of the relative retention time of peak III in sample [E]: U.K.

where:

RRT _III [E]

=

the relative retention time of peak III in sample [E],

RT _III [E]

=

the retention time of peak III in sample [E] obtained in 8.4.2,

RT _III [5]

=

the retention time of peak III in control sample [5] obtained in 8.5.3.

9.1.4. Experiments have shown that there is a linear relation between the relative retention time of peak III, i.e. RRT _III [E] and the percentage of whey powder added up to 10 % U.K.

• The RRT _III [E] is < 1,000 when the whey content is > 5 %;

• The RRT _III [E] is ≥ 1,000 when the whey content is ≤ 5 %.

The uncertainty allowed for the values of RRT _III is ± 0,002.

Normally the value of RRT _III [0] deviates little from 1,034. Depending on the condition of the columns, the value may approach 1,000, but it shall always be greater.

9.2. Calculation of the percentage of rennet whey powder in the sample: U.K.

W = S _III [E] – [1, 3 + (S _III [0] – 0,9)]

where:

W

=

the percentage m/m of rennet whey in the sample [E];

S _III [E]

=

the relative area of peak III of test sample [E] obtained as in 9.1.2;

1,3

=

represents the relative average area of peak III expressed in grams of rennet whey per 100 g determined in non-adulterated skimmed milk powder of various origins. This figure was obtained experimentally;

S _III [0]

=

represents the relative area of peak III which is equal to R _III  × A _III [0]. These values are obtained in 9.1.1 and 8.5.3 respectively;

(S _III [0] – 0,9)

=

represents the correction to be made to the relative average area 1,3 when S _III [0] is not equal to 0,9. Experimentally the relative average area of peak III of the control sample [0] is 0,9.

9.3. Accuracy of the procedure U.K.

9.3.2. Reproducibility U.K.

The difference between two single and independent results, obtained in two different laboratories on identical test material shall not exceed 0,4 % m/m.

9.4. Interpretation U.K.

9.4.1. Assume the absence of whey if the relative area of peak III, S _III [E] expressed in grams of rennet whey per 100 g of the product is ≤ 2,0 + (S _III [0] – 0,9) U.K.

where

2,0	is the maximum value allowed for the relative area of peak III taking into account the relative average area of peak III, i.e. 1,3, the uncertainty due to variations in the composition of skimmed milk powder and the reproducibility of the method (9.3.2),
(S III [0] – 0,9)	is the correction to be made when the area S III [0] is different from 0,9 (see point 9.2)

9.4.2. If the relative area of peak III, S _III [E] is > 2,0 + (S _III [0] – 0,9) and the relative area of peak II, S _II [E] ≤ 160, determine the rennet whey content as indicated in point 9.2. U.K.

9.4.3. If the relative area of peak III, S _III [E] is > 2,0 + (S _III [0] – 0,9) and the relative area of peak II, S _II [E] ≤ 160, determine the total protein content (P %); then examine graphs 1 and 2. U.K.

9.4.3.1. The data obtained after analysis of samples of unadulterated skimmed milk powders with a high total protein content have been assembled in graphs 1 and 2. U.K.

The continuous line represents the linear regression, the coefficients of which are calculated by the least squares method.

The dashed straight line fixes the upper limit of the relative area of peak III with a probability of not being exceeded in 90 % of cases.

The equations for the dashed straight lines of graphs 1 and 2 are:

S III = 0,376 P % – 10,7	(graph 1),
S III = 0,0123 S II [E] + 0,93	(graph 2),

respectively where:

S _III

is the relative area of peak III calculated either according to total protein content or according to the relative area of peak S _II [E],

P %

is the total protein content expressed as a percentage, by weight,

S _II [E]

is the relative area of sample calculated in point 9.1.2.

These equations are equivalent to the figure of 1,3 mentioned in point 9.2.

The discrepancy (T ₁ and T ₂ ) between the relative area S _III [E] found and the relative area S _III is given by means of the following: T ₁ = S _III [E] – [(0,376 P% – 10,7) + (S _III [0] – 0,9)]T ₂ = S _III [E] – [(0,0123 S _II [E] + 0,93) + (S _III [0] – 0,9)]

9.4.3.2.

If T 1 and/or T 2	are zero or less, the presence of rennet whey cannot be determined.
If T 1 and T 2	exceed zero, rennet whey is present.

The rennet whey content is calculated according to the following formula: W = T ₂ + 0,91

where:

0,91 is the distance on the vertical axis between the continuous and dotted straight lines.

7.2. Store the sample in conditions which preclude any deterioration or change in composition. U.K.

8. PROCEDURE U.K.

8.1. Preparation of the test sample U.K.

Transfer the milk powder into a container with a capacity of about twice the volume of the powder, fitted with an airtight lid. Close the container immediately. Mix the milk powder well by means of repeated inversion of the container.

8.2. Test portion U.K.

Weigh 2,00 ± 0,001 g of test sample into a centrifuge tube (6.2) or suitable stoppered flask (50 ml).

Note: In the case of mixtures, weigh such an amount of the test sample that the defatted sample portion corresponds to 2,00 g. U.K.

8.3. Removal of fat and proteins U.K.

8.3.1. Add 20,0 ml of warm water (50 °C) to the test portion. Dissolve the powder by shaking for five minutes using a mechanical shaker (6.3). Place the tube into the water bath (6.10) and allow to equilibrate to 25 °C U.K.

8.3.2. Add 10,0 ml of the trichloroacetic acid solution of ca. 25 °C (5.1) constantly over two minutes, while stirring vigorously with the aid of the magnetic stirrer (6.4). Place the tube in a water bath (6.10) and leave for 60 minutes U.K.

8.3.3. Centrifuge (6.2) 2 200 g for 10 minutes, or filter through paper (6.6), discarding the first 5 ml of filtrate U.K.

8.4. Chromatographic determination U.K.

8.4.1. The reversed-phase HPLC method excludes the possibility false-positive results due to the presence of acid buttermilk powder. U.K.

8.4.2. Before the reversed phase HPLC-analysis is carried out, the gradient conditions should be optimised. A retention time of 26 ± 2 minutes for CMP _A is optimal for gradient systems having a dead volume of about 6 ml (volume from the point where the solvents come together to the volume of the injector loop, inclusive). Gradient systems having a lower dead volume (e.g. 2 ml) should use 22 minutes as an optimal retention time U.K.

Take solutions of the standard samples (5.4) without and with 50 % rennet whey.

Inject 100 μl of supernatant or filtrate (8.3.3) into the HPLC apparatus operating at the scouting gradient conditions given in Table 1.

Table 1

Scouting gradient conditions for optimisation of the chromatography

Time (min)	Flow (ml/min)	% A	% B	Curve
Initial	1,0	90	10	*
27	1,0	60	40	linear
32	1,0	10	90	linear
37	1,0	10	90	linear
42	1,0	90	10	linear

Comparison of the two chromatograms should reveal the location of the peak of CMP _Α .

Using the formula given below, the initial solvent composition to be used for the normal gradient (see 8.4.3) can be calculated % B = 10 – 2,5 + (13,5 + (RT _cmpA – 26) / 6) * 30 / 27 % B = 7,5 + (13,5 + (RT _cmpA – 26) / 6) * 1,11

Where:

RT _cmpA

:

retention time of CMP _Α in the scouting gradient

10

:

the initial % B of the scouting gradient

2,5

:

% B at midpoint minus % B at initial in the normal gradient

13,5

:

midpoint time of the scouting gradient

26

:

required retention time of CMP _Α

6

:

ratio of slopes of the scouting and normal gradient

30

:

% B at initial minus % B at 27 minutes in the scouting gradient

27

:

run-time of the scouting gradient.

8.4.3. Take solutions of the test samples U.K.

Inject 100 μl of accurately measured supernatant or filtrate (8.3.3) into the HPLC apparatus operating at a flow rate of 1,0 ml of eluent solution (5.2) per minute.

The composition of the eluent of the start of the analysis is obtained from 8.4.2. It is normally close to A:B = 76:24 (5.2). Immediately after the injection a linear gradient is started, which results in a 5 % higher percentage of B after 27 minutes. Subsequently a linear gradient is started, which brings the eluent composition to 90 % B in five minutes. This composition is maintained for five minutes, after which the composition is changed, via a linear gradient in five minutes to the initial composition. Depending on the internal volume of the pumping system, the next injection can be made 15 minutes after reaching the initial conditions.

Note 1. The retention time of the CMP _A should be 26 ± 2 minutes. This can be achieved by varying the initial and end conditions of the first gradient. However, the difference in the % B for the initial and end conditions of the first gradient shall remain 5 % B. U.K.

Note 2. The eluents should be degassed sufficiently and should also remain degassed. This is essential for proper functioning of the gradient pumping system. The standard deviation for the retention time of the CMP _A peak should be smaller than 0,1 minutes (n = 10). U.K.

Note 3. Every five samples the reference sample [5] should be injected and used to calculate a new response factor R. (9.1.1). U.K.

8.4.4. The results of the chromatographic analysis of the test sample (E) are obtained in the form of a chromatogram in which the CMP _A peak is identified by its retention time of about 26 minutes U.K.

The integrator (6.11.6) automatically calculates the peak height H of the CMP _A peak. The baseline location should be checked in every chromatogram. The analysis or the integration should be repeated if the baseline was incorrectly located.

Note: If the CMP _A peak is sufficiently separated from other peaks valley-to-valley baseline allocation should be used, otherwise use dropping perpendiculars to a common baseline, which should have starting point close to the CMP _A peak (thus not at t = 0 min!).Use for the standard and the samples the same type integration type and check in case of common baseline its consistency for the samples and the standard. U.K.

It is essential to examine the appearance of each chromatogram prior to quantitative interpretation, in order to detect any abnormalities due either to malfunctioning of the apparatus or the column, or to the origin and nature of the sample analysed. If in doubt, repeat the analysis.

8.5. Calibration U.K.

8.5.1. Apply exactly the procedure described from point 8.2 to point 8.4.4 to the standard samples (5.4.1 to 5.4.2). Use freshly prepared solutions, because CMP degrades in an 8 % trichloroacetic acid environment at room temperature. At 4 °C the solution remains stable for 24 hours. In the case of long series of analyses the use of a cooled sample tray in the automatic injector is desirable U.K.

Note: 8.4.2. may be omitted if the % B at initial conditions is known from previous analyses. U.K.

The chromatogram of the reference sample [5] should be analogous to Figure. 1. In this figure the CMP _A peak is preceded by two small peaks. It is essential to obtain a similar separation.

8.5.2. Prior to chromatographic determination of the samples inject 100 μl of the standard sample without rennet whey [0] (5.4.1) U.K.

The chromatogram should not show a peak at the retention time of the CMP _A peak.

8.5.3. Determine the response factors R by injecting the same volume of filtrate (8.5.1) as used for the samples. U.K.

9. EXPRESSION OF RESULTS U.K.

9.1. Method of calculation and formulae U.K.

9.1.1. Calculation of the response factor R: U.K.

CMP _A peak: R = W/H

Where:

R

=

the response factor of the CMP _A peak

H

=

the height of the CMP _A peak

W

=

the quantity of whey in the standard sample [5].

9.2. Calculation of the percentage of rennet whey powder in the sample U.K.

R

=

the response factor of the CMP _A peak (9.1.1)

H(E)

=

the height of the CMP _A peak of the sample (E)

If W(E) is greater than 1 % and the difference between the retention time and that of the standard sample [5] is smaller than 0,2 minutes then rennet whey solids are present.

9.3. Accuracy of the procedure U.K.

9.3.1. Repeatability U.K.

The difference between the results of two determinations carried out simultaneously or in rapid succession by the same analyst using the same apparatus on identical test material shall not exceed 0,2 % m/m.

9.3.2. Reproducibility U.K.

Not determined.

9.3.3. Linearity U.K.

From 0 to 16 % of rennet whey a linear relationship should be obtained with a coefficient of correlation > 0,99.
