13.—(1) Subject to paragraph (2), an inspector shall obliterate the stamp on any automatic catchweighing instrument which—
(a)on testing in accordance with clause 5.3 of Part 1 of OIML R51 fails to fall within the prescribed limits of error for in-service testing; or
(b)fails to comply with any other appropriate requirement of these Regulations.
(2) Except as provided by regulation 14, where any automatic catchweighing 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 automatic catchweighing 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.
