  "heading": "Interpretation",
  "text": "(1) In these Regulations—\n“the 1985 Act” means the Weights and Measures Act 1985;\n“accuracy class” means the accuracy class, in respect of an automatic rail-weighbridge, determined by the Secretary of State and specified in the certificate of approval, being one of the accuracy classes 0.2, 0.5, 1 or, for the purposes of weighing waste (as defined in Schedule 3) only, 2: provided always that, except when used for the purposes of weighing waste, the accuracy class in respect of that automatic rail-weighbridge may be different for wagon weighing to that for train weighing;\n“automatic rail-weighbridge” means an instrument which—\n(i)is used to determine the mass of a railway wagon when it is weighed in motion by using the action of gravity without the intervention of an operator;\n(ii)follows a predetermined programme of automatic processes characteristic of the instrument; and\n(iii)has one or more load receptors inclusive of rails for conveying railway vehicles and includes such of the other components described in Schedule 1 as are specified in the certificate of approval;\n“certificate of approval” means a certificate of approval of a pattern of an automatic rail-weighbridge granted or renewed by the Secretary of State under section 12 of the 1985 Act;\n“control instrument” means a non-automatic weighing instrument used to determine the mass of a reference wagon;\n“initial verification testing” means testing in accordance with the provisions of regulation 6(c);\n“instrument” has the same meaning as that for automatic rail-weighbridge;\n“load receptor” means the part of the weigh zone that is intended to receive the load and which realises a change in the balance of the automatic rail-weighbridge when a load is placed upon it; and “multiple load receptors” means two or more load receptors placed in series or in parallel that are used as a single load receptor for weighing a wagon that is entirely supported on the load receptors;\n“maximum capacity” means the largest load which the automatic rail-weighbridge is designed to weigh-in-motion before totalising;\n“maximum wagon weight” means the largest in-motion load which the automatic rail-weighbridge is approved to weigh for a particular site;\n“minimum capacity” means the load below which a weighing-in-motion result before totalising may be subject to an excessive relative error;\n“minimum wagon weight” means the wagon weight (when the wagon is unloaded) below which a weighing-in-motion result may be subject to an excessive relative error;\n“OIML R 106” means the International Recommendation OIML R 106 of the Organisation Internationale de Métrologie Légale relating to automatic rail-weighbridges (Edition 1997 (E));\n“prescribed limits of error” has the meaning set out in regulation 9(3);\n“reference wagon” means a railway goods vehicle that is recognised by the automatic rail-weighbridge as a vehicle to be weighed being—\n(a)of known weight;\n(b)typical of those to be used for weighing on the automatic rail-weighbridge;\nand which has been selected for the purposes of in-motion testing;\n“scale interval” or “d” means a value expressed in units of mass for weighing-in-motion that is the difference between—\n(a)the values corresponding to two consecutive scale marks for analogue indication; or\n(b)two consecutive indicated or printed values for digital indication;\n“scale interval for stationary load” means the scale interval used for static tests;\n“the stamp” or “verification mark” means the prescribed stamp ;\n“total train” means a number of coupled wagons whose totalised weight is to be obtained;\n“wagon” means a loaded or unloaded railway goods vehicle that is recognised by the automatic rail-weighbridge as a vehicle to be weighed;\n“weighing-in-motion” means weighing objects that are in motion; and\n“weigh zone” means the zone in which a wagon must be located when it is to be weighed.\n(2) Any expression or procedure which is not defined in these Regulations and is used both in these Regulations and OIML R 106 shall bear the same meaning as in OIML R 106.",
