(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.
14.—(1) An inspector shall obliterate the stamp on any automatic catchweighing 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 10.
(2) Subject to paragraph (3), an inspector shall obliterate the stamp on any automatic catchweighing instrument which has, since it was last stamped, been the subject of any of the following occurrences, that is to say, adjustment, alteration, addition, repair or replacement which could, in the opinion of the inspector, have affected its accuracy or function.
(3) Where an automatic catchweighing instrument has been subjected to one or other of the occurrences in paragraph (2) and the chief inspector of weights and measures for the area in which the instrument is situated has been furnished in writing with details of the occurrence, an inspector may obliterate the stamp.

(ii)are likely prematurely to degrade the metrological characteristics of the instrument.
16.—(1) Subject to paragraph (2), for the purposes of these Regulations, the obliteration of any one stamp on any automatic catchweighing instrument shall be deemed to be the obliteration of all other stamps on that instrument.
(2) As an exception for the purposes of section 11(2)(b) of the Act (express provision authorising the use for trade or possession for such use of equipment where the stamp remains undefaced), in the application of paragraph (1) to an automatic catchweighing instrument which is also capable of functioning as a non-automatic weighing instrument to which the Regulations specified in regulation 3(2) apply, the obliteration of any stamp shall not be taken to preclude the use for trade or possession for such use of the instrument in its measurement function as such a non-automatic weighing instrument, unless the instrument bears a disqualification sticker as provided for in regulation 23 or 24 of the Non-automatic Weighing Instruments Regulations 2000.
17.—(1) In regulation 3 (application) of the Weighing Equipment (Non-automatic Weighing Machines) Regulations 2000—
