Regulations2(1), 4(1), 28 and 29

SCHEDULE 1

PART 1 ESSENTIAL REQUIREMENTS

1.  The essential requirements are the relevant requirements relating to relevant instruments contained in Annex 1 and Annex M1-002 set out in this Part of this Schedule.

Definitions

2.  In this Schedule—

“base conditions” means the specified conditions to which the measured quantity of gas is converted;

“climatic environments” means the conditions in which relevant instruments may be used;

“critical change value” means the value at which the change in the measurement result is considered undesirable;

“disturbance” means an influence quantity having a value within the limits specified in the appropriate requirement but outside the specified rated operating conditions of the relevant instrument. An influence quantity is a disturbance if for that influence quantity the rated operating conditions are not specified;

“influence quantity” means a quantity that is not the measurand but that affects the result of measurement;

“MPE” means the maximum permissible error value as set out in paragraph 13;

“measurand” means the particular quantity subject to measurement;

“minimum flowrate” (“Qmin”) means the lowest flowrate at which the relevant instrument provides indications that satisfy the requirements regarding MPE;

“maximum flowrate” (“Qmax”) means the highest flowrate at which the relevant instrument provides indications that satisfy the requirements regarding MPE;

“overload flowrate” means the highest flowrate at which the relevant instrument operates for a short period of time without deteriorating;

“rated operating conditions” means the values for the measurand and influence quantities making up the normal working conditions of a relevant instrument; and

“transitional flowrate” (“Qt”) means the flowrate occurring between the maximum and minimum flowrates at which the flowrate range is divided into two zones, the “upper zone” and the “lower zone”. Each zone has a characteristic MPE.

Allowable errors

3.—(1) The manufacturer shall specify the climatic, mechanical and electromagnetic environments in which the relevant instrument is intended to be used, power supply and other influence quantities likely to affect its accuracy, taking account of the requirements in this Schedule.

(a) Climatic environments—

The manufacturer shall specify the upper temperature limit and the lower temperature limit from any of the values in Table 1 and indicate whether the relevant instrument is designed for condensing or non-condensing humidity as well as the intended location for the instrument, i.e, open or closed.

Table 1

	Temperature Limits
Upper Temperature Limit	30 °C	40 °C	55 °C	70 °C
Lower Temperature Limit	5 °C	-10 °C	-25 °C	-40 °C

(b) Mechanical environments—

(i) Mechanical environments are classified into classes M1 to M3 as described below—

• M1: This class applies to relevant instruments used in locations with vibration and shocks of low significance, for example, instruments fastened to light supporting structures subject to negligible vibrations and shocks transmitted from, for example, local blasting or pile-driving activities or slamming doors.

• M2: This class applies to relevant instruments used in locations with significant or high levels of vibration and shocks, for example, transmitted from machines and passing vehicles in the vicinity, or adjacent to heavy machines or conveyor belts.

• M3: This class applies to relevant instruments used in locations where the level of vibration and shock is high and very high, for example, instruments mounted directly on machines or conveyor belts.

(ii) The following influence quantities shall be considered in relation with mechanical environments—

(aa) vibration;

(bb) mechanical shock.

(c) Electromagnetic environments—

(i) Electromagnetic environments, in relation to relevant instruments that are constructed using electronic components, are classified into classes E1 and E2 as described below.

• E1: This class applies to relevant instruments used in locations with electromagnetic disturbances corresponding to those likely to be found in residential, commercial and light industrial buildings.

• E2: This class applies to relevant instruments used in locations with electromagnetic disturbances corresponding to those likely to be found in other industrial buildings.

(ii) The following influence quantities shall be considered in relation with electromagnetic environments—

(aa) voltage interruptions;

(bb) short voltage reductions;

(cc) voltage transients on supply lines and/or signal lines;

(dd) electrostatic discharges;

(b) the damp heat cyclic test is appropriate where condensation is important. In conditions where non-condensing humidity is a factor the damp-heat steady state is appropriate.

Repeatability

5.  The application of the same measurand under the same conditions of measurement shall result in the close agreement of successive measurements. The difference between the measurement results shall be small when compared with the MPE.

Discrimination and sensitivity

6.  A relevant instrument shall be sufficiently sensitive and the discrimination threshold shall be sufficiently low for the intended measurement task.

Reliability

7.  A relevant instrument shall be designed to reduce as far as possible the effect of a defect that would lead to an inaccurate measurement result, unless the presence of such a defect is obvious.
