(i)serves to determine the mass of a load by using the action of gravity on that load without the intervention of an operator;
(ii)follows a predetermined programme of automatic processes characteristic of the instrument;
(iii)systematically sub-divides material from bulk into separate loads of a predetermined and virtually constant mass; and
(iv)effects an automatic feed and weighing of those loads with the appropriate control and discharge devices;

(2) An inspector shall not stamp a filling instrument in accordance with paragraph (1) if it bears any mark which, in his opinion, might reasonably be mistaken for the stamp, or any statement or mark (other than an inspector’s stamp) which purports to be or, in the opinion of the inspector, might reasonably be mistaken for an expression of approval or guarantee of accuracy by any body or person.
Manner of obliteration of stampsE+W+S
11. An inspector shall obliterate a stamp, in accordance with the requirements of these Regulations, by means of punches or pincers of suitable sizes of a six-pointed star design as shown in the following illustration–
Obliteration of stampsE+W+S
12.—(1) Subject to paragraph (2), an inspector shall obliterate the stamp on any filling instrument which–
(a)on testing in accordance with clause 5.4 of Part 1 of OIML R 61 fails to fall within the prescribed limits of error in relation to obliteration of the stamp; or
(b)fails to comply with any other appropriate requirement of these Regulations.
(2) Except as provided by regulation 13, where any filling instrument does not fully comply with the requirements of these Regulations, but the nature or degree of the non-compliance is not, in the inspector’s opinion, such as to require the immediate obliteration of the stamp, he shall give to the proprietor or any person in control of the filling instrument a notice calling on him to have the instrument corrected within a stated period not exceeding 28 days, and shall obliterate the stamp if the correction has not been made within the stated period.
13. An inspector shall obliterate the stamp on any filling instrument which has, since it was last stamped, had any alteration or addition made to it such that it could not be passed as fit for use for trade under regulation 9.
14. An inspector may obliterate the stamp on any filling instrument which–
(a)has, since it was last stamped, been the subject of any adjustment, alteration, addition, repair or replacement–
(i)which could, in the opinion of the inspector, have affected its accuracy or function; and
(ii)where the chief inspector of weights and measures for the area where the filling instrument is located has been furnished in writing with details of that adjustment, alteration, addition, repair or replacement;
(b)is in use for trade for a particular purpose and–
(i)which does not meet the requirements of Schedule 2 in respect of minimum or maximum capacity; or
(ii)for which purpose, in the opinion of the inspector, it is otherwise unsuitable; or
(c)is in use for trade in circumstances where the filling instrument is subjected to any extraordinary environmental or operating conditions which, in the opinion of the inspector,–
(i)prevent the filling instrument operating consistently and correctly; or
(ii)are likely prematurely to degrade the metrological characteristics of the filling instrument.
15.—(1) For the purposes of these Regulations, the obliteration of any one stamp on any filling instrument shall, subject to paragraph (2), be deemed to be the obliteration of all other stamps on that instrument.
(2) Where the stamp on one filling instrument forming part of an interconnected system is obliterated, paragraph (1) shall not apply so as to prevent the system or any other filling instrument in the system being used provided that the integrity of the remainder of the system is unimpaired.

Explanatory Note
(This note is not part of the Regulations)
These Regulations implement, in Great Britain, International Recommendation OIML R 61 of the Organisation Internationale de Métrologie Légale relating to automatic gravimetric filling instruments (Edition 1996 (E)), to the extent that the Recommendation applies to such instruments following the grant or renewal of a certificate of approval of a pattern by the Secretary of State under section 12 of the Weights and Measures Act 1985 (the 1985 Act).
2. Regulation 3 applies the Regulations to “filling instruments”, as defined in regulation 2(1)(a), which are prescribed for the purposes of section 11(1) of the 1985 Act (certain equipment to be passed and stamped for use for trade). The Regulations do not apply in the circumstances described in regulations 3(2) and (3). There is a transitional exclusion set out in regulation 4(1) but this is subject to the case of a “filling instrument” which bears the marking “R 61”.E+W+S
3. Regulation 5 sets out some general duties relating to the use for trade of a “filling instrument” in terms of erection and installation (Schedule 1), use and manner of use (Schedule 2) and compliance with the accuracy classes specified in Schedule 3. Regulation 6 provides for certain requirements which must be satisfied before a “filling instrument” is passed as fit for use for trade for the purposes of the Regulations: these relate to compliance with a pattern in respect of which a “certificate of approval” remains in force, the application of descriptive markings in accordance with Schedule 4 and provisions in respect of initial verification testing carried out by an inspector in accordance with the procedure specified in clause 5.3 of Part 1 of OIML R 61. Regulation 7 incorporates some supplementary requirements relating to the testing, passing as fit for use for trade and stamping of any “filling instrument”. Regulation 8 makes provision for “filling instruments” imported from another EEA State into Great Britain not to be tested by an inspector when an inspector is presented with the “requisite documentation” (as defined in that regulation), unless he is not satisfied with that “requisite documentation”.E+W+S
4. Regulation 9 specifies circumstances where an inspector shall not pass a “filling instrument” as fit for use for trade, including a failure to comply with the prescribed limits of error in accordance with the provisions of regulation 9(3) and Schedule 5. Provision is also made, in regulation 9(2), for circumstances in which a “filling instrument” imported from another EEA State shall not be passed as fit for use for trade.E+W+S
5. Regulations 10 to 15 relate to the stamping and obliteration of stamps on “filling instruments”.E+W+S
