Application 2 1 Subject to paragraph (2) below, these Regulations shall apply to all measuring equipment for use for trade in the making of any measurement of liquid fuel in a quantity not exceeding 20 gallons if it is constructed to measure in imperial units, or 100 litres if it is constructed to measure in metric units, other than equipment for use for trade in the making of any measurement of liquefied petroleum gas; and measuring equipment to which these Regulations apply is hereby prescribed for the purposes of section 11(1) of the Act. 2 Nothing in these Regulations shall apply to any measuring equipment for use for the measurement by capacity of liquid fuel in a quantity not exceeding 100 litres which, in accordance with a programme of automatic control and without the intervention of an operator during the measuring process, measures quantities of those products to a constant nominal capacity, the quantities being kept separate. Purposes of use for trade 3 No person shall use for trade any measuring equipment fitted with a price to pay indicating device in digital form if it indicates during a measuring operation a part of a penny in the amount of the price to be paid by the buyer. Principles of construction and marking of measuring equipment 4 1 All measuring equipment shall be made in accordance with a pattern in respect of which a certificate of approval is in force, and in these Regulations “the pattern” means the particular pattern in accordance with which any particular measuring equipment is so made. 2 Any measuring equipment first submitted for testing with a view to passing as fit for use for trade before 1st January 1981 may, and any measuring equipment first submitted for such testing on or after such date shall, be legibly and durably marked with the number of the certificate of approval or of the notice of examination, preceded by the words “Certification No. ”, “Cert. No.” or “Notice No.” as the case may be. 5 All measuring equipment shall be legibly and durably marked with the name of the manufacturer. 6 Every individual sales indicator fitted to measuring equipment shall be so arranged that— a the indicator reading is capable of being set to zero before a delivery commences; and b the indicator reading cannot be advanced by any means other than by the proper operation of the equipment. 7 Every marking, notice, inscription or indication on measuring equipment referring to the method of operation or to the quantity of liquid fuel delivered shall be conspicuously, legibly and durably marked in a suitable position in plain block characters on a plain background and in distinct contrast to it. 8 1 Subject to paragraphs (2) and (3) below, all measuring equipment which forms part of a fixed installation shall be so positioned that a buyer may readily obtain a clear unobstructed view— a of all the operations carried out by any other person using the equipment to measure the liquid fuel being supplied to the buyer; and b of any device on the equipment which is designed to indicate to the buyer the quantity supplied or the amount payable or that delivery is being effected. 2 Paragraph (1) above shall not apply to any equipment for use only for measuring kerosene except where the equipment is— a situated on premises where petrol is sold; or b used for measuring kerosene in the course of delivery into the fuel tanks of vehicles. 3 Paragraph (1) above shall not apply to any equipment normally used for the measurement of lubricants in the absence of the buyer. Manner of use for trade 9 All measuring equipment shall be used for trade in such a manner that every individual sales indicator shall be set to zero before a delivery commences. Testing 10 All measuring equipment shall be tested by an inspector under practical working conditions with the liquid fuel that the equipment is intended to deliver. 11 No measuring equipment shall be tested unless it is complete with all its parts as described in the certificate of approval or notice of examination, as the case may be. 12 All measuring equipment which is to be permanently fixed in the position in which it is to be used shall be tested, passed as fit for use for trade and stamped only when completely erected ready for use and installed at the place where it is to be used. 13 1 Before testing any measuring equipment fitted with a discharge hose, the inspector shall ensure that liquid fuel has first been passed through the equipment: Provided that this regulation shall not apply to equipment used for the measurement of such liquid fuel where the delivery system remains permanently full up to the outer extremity of the discharge hose. 2 In paragraph (1) above the expression “hose” includes rigid pipe work. 14 For the purposes of the performance by an inspector of his functions under the Act or these Regulations relating to inspection, testing, passing as fit for use for trade and stamping of any measuring equipment, a person submitting such equipment to an inspector or who an inspector has reasonable cause to believe has possession of such equipment for use for trade shall, if requested, provide for the inspector’s use such liquid fuel and other equipment as the inspector may reasonably require, and any liquid fuel so provided shall be returned to the person in question or be placed in another suitable receptacle reasonably convenient for the purpose and nominated and provided by the proprietor or person in charge of the equipment. 15 1 An inspector may open any locked or sealed tank or container for the purpose of testing any measuring equipment or the return of liquid fuel withdrawn during testing, and any liquid fuel so withdrawn shall, upon the conclusion of the test, be forthwith returned to the tank or container from which it was withdrawn if the inspector is of the opinion that it is practicable and desirable so to do and the proprietor or person in charge of the equipment does not object; otherwise, it shall be placed in another suitable receptacle reasonably convenient for the purpose and nominated and provided by the proprietor or person in charge of the equipment. 2 The inspector, if requested, shall give to the proprietor or person in charge of the said equipment a signed and dated statement of the quantity of such liquid fuel withdrawn from the tank or container and returned or placed as aforesaid. 16 An inspector shall securely re-fasten any tank or container opened under regulation 15(1) above immediately after the conclusion of the test and the return of any liquid fuel withdrawn during testing or its placing in another receptacle; and for this purpose he shall replace any seal or link broken by him in opening the said tank or container with a seal upon which he shall affix the stamp. Prescribed limits of error 17 1 The prescribed limits of error relating to any measuring equipment shall be those set out in Table 1 in the Schedule to these Regulations: Provided that— a except in the case of equipment constructed to deliver a fixed quantity only, for a quantity equivalent to the minimum delivery of the equipment the prescribed limits of error shall be those set out in Table 2 in the Schedule to these Regulations; b where a quantity indicated by the measuring equipment is larger than the minimum delivery of the equipment, then the prescribed limit of error for the said quantity shall never be less than that prescribed for the quantity equivalent to the minimum delivery of the equipment set out in the said Table 2; c if, on testing with a view to passing as fit for use for trade, the errors on all the quantities of individual grades of liquid fuel indicated by the measuring equipment during the tests are all errors in excess or all errors in deficiency then, notwithstanding that they are all within the prescribed limits of error set out in the said Table 1 or 2 as appropriate, at least one of them shall not exceed either— i one-half of the prescribed limits of error set out in the said Table 1 or 2 as appropriate; or ii 0.3% of the quantity indicated; whichever is the greater; d in relation to the retesting of any equipment fitted with a price computing device which— i is, in the opinion of an inspector, only required to be retested as a result of an adjustment of that device occasioned by a change in price; and ii has previously been tested and passed as fit for use for trade (but not since the said adjustment was made), the prescribed limits of error shall be the amounts set out in the said Table 1 or 2 as appropriate in relation to obliteration of the stamp; and e in relation to the retesting of any equipment converted to indicate the quantity delivered in metric units which— i is, in the opinion of an inspector, only required to be retested as a result of such conversion; and ii has previously been tested and passed as fit for use for trade (but not since the said conversion was made), the prescribed limits of error shall be the amounts set out in the said Table 1 or 2 as appropriate in relation to obliteration of the stamp. 2 On the testing of any measuring equipment fitted with a price computing device the difference between the price indicated by that device and the price computed on the basis of the unit price and of the quantity indicated for test purposes shall not exceed the price of the quantity equal to the error in deficiency set out in the said Table 2 for a quantity equivalent to the minimum delivery of the equipment in relation to obliteration of the stamp. Passing as fit for use for trade 18 1 No measuring equipment shall be passed as fit for use for trade unless— a it complies with all the appropriate requirements of these Regulations; and b on testing it measures and delivers the liquid fuel with which it is tested to within the prescribed limits of error when it is operated at any reasonable speed, the speed of operation in respect of any individual delivery being as uniform as practicable. 2 No measuring equipment fitted with a price to pay indicating device in digital form shall be passed as fit for use for trade if it is capable of indicating during a measuring operation a part of a penny in the amount of the price to be paid by the buyer. Stamping 19 1 All measuring equipment shall be provided with such sealing arrangements as may be contained in the certificate of approval or the notice of examination in respect of that pattern. 2 The stamp shall be placed on every plug, seal or sealing device authorised in accordance with paragraph (1) above. 20 No measuring equipment shall be stamped in accordance with regulation 19(2) above if it bears any mark which, in the opinion of the inspector, might reasonably be mistaken for the stamp. Obliteration of stamps 21 Stamps shall be obliterated by an inspector, 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— 22 1 An inspector shall obliterate the stamp on any measuring equipment which— a fails upon testing to fall within the prescribed limits of error in relation to obliteration of the stamp set out in Table 1 or 2 in the Schedule hereto as appropriate to the case; or b fails to comply with any other appropriate requirement of these Regulations; Provided that where any measuring equipment 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 person in charge of the equipment a notice calling on him to have the equipment 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. 2 An inspector shall obliterate the stamp on any measuring equipment 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 18 above. 3 Where any measuring equipment has, since it was last stamped, been the subject of any adjustment, alteration, addition, repair or replacement which could, in the opinion of the inspector, have affected its accuracy or function, he may obliterate the stamp on that equipment. 23 For the purposes of these Regulations, the obliteration, destruction or defacement of any one stamp on any measuring equipment shall be deemed to be the obliteration of all other stamps on that equipment, except where the stamp has been lawfully obliterated under regulation 24 or 25 below. Lawful use for trade of equipment where stamps destroyed, obliterated or defaced 24 1 It shall be lawful to destroy, obliterate or deface a stamp on any measuring equipment, and it shall not be a contravention of section 11(2) of the Act to use such equipment for trade during the relevant period by reason only that a stamp on it has been lawfully destroyed, obliterated or defaced (such destruction, obliteration or defacement being in this Regulation referred to as “the occurrence”) if— a the person responsible for the occurrence is, or is the duly authorised agent of, the proprietor of the equipment or a person who is the manufacturer, or is regularly engaged in the repair, of equipment for measuring liquid fuel; b the occurrence was confined to the stamp protecting the price computing device of the equipment and the stamp on the indicator of the price per gallon (or per half a gallon or per litre as the case may be); c the occurrence was only to permit an adjustment of that device and that indicator; and d notification in writing complying with paragraph (2) below of the occurrence has been given by the proprietor of the equipment or his duly authorised agent before the occurrence to the chief inspector of weights and measures for the area in which the equipment is situated. 2 The notification referred to in paragraph (1) above shall contain the following information— a the location of, and particulars by which, the equipment may be identified; b the intended date of the occurrence; c the business name and address of the proprietor or other person referred to in paragraph (1)(a) above; and d the name and address of the person giving the notification. 3 In paragraph (1) above “relevant period” means a period of 28 days beginning with the day on which the notification referred to in that paragraph is given in accordance with that paragraph. 25 1 It shall be lawful to destroy, obliterate or deface a stamp on any measuring equipment, and it shall not be a contravention of section 11(2) of the Act to use such equipment for trade during the relevant period by reason only that a stamp on it has been lawfully destroyed, obliterated or defaced (such destruction, obliteration or defacement being in this regulation referred to as “the occurrance”) if— a the person responsible for the occurrence is, or is the duly authorised agent of, a person who is the manufacturer, or is regularly engaged in the repair, of equipment for measuring liquid fuel; b the occurrence was only to facilitate or permit the adaptation of the equipment to measure in metric quantities; c where the occurrence relates to the stamp on the measuring equipment protecting the calibration of the measuring device, the person responsible for the occurrence has attached to the equipment some seal or other device which must be defaced or removed before the calibration of the measuring device can be adjusted; and d notification in writing complying with paragraph (2) below of the occurrence has been given by the proprietor of the equipment or his duly authorised agent before the occurrence to the chief inspector of weights and measures for the area in which the equipment is situated. 2 The notification referred to in paragraph (1) above shall contain the following information— a the location of, and particulars by which, the equipment may be indentified; b the intended date of the occurrence; c the business name and address of the person referred to in paragraph (1)(a) above; d the name and address of the person giving the notification; and e whether the occurrence is of a type mentioned in paragraph (3)(a) or (3)(b) below. 3 In paragraph (1) above, “relevant period” means— a where the stamp on the measuring equipment protecting the calibration of the measuring device remains intact and notification of the fact that some other stamp has been destroyed, obliterated or defaced has been given in accordance with that paragraph, a period of 28 days beginning when notification is so given; or b where the stamp on the measuring equipment protecting the calibration of the measuring device has been destroyed, obliterated or defaced and notification of the destruction, obliteration or defacement of that stamp has been given in accordance with that paragraph, a period of 5 days beginning when notification is so given.
