The Weighing Equipment (Automatic Rail-weighbridges) Regulations 2003

InterpretationE+W+S

2.—(1) In these Regulations—

“the 1985 Act” means the Weights and Measures Act 1985;

“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;

“automatic rail-weighbridge” means an instrument which—

“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;

“control instrument” means a non-automatic weighing instrument used to determine the mass of a reference wagon;

“initial verification testing” means testing in accordance with the provisions of regulation 6(c);

“instrument” has the same meaning as that for automatic rail-weighbridge;

“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;

“maximum capacity” means the largest load which the automatic rail-weighbridge is designed to weigh-in-motion before totalising;

“maximum wagon weight” means the largest in-motion load which the automatic rail-weighbridge is approved to weigh for a particular site;

“minimum capacity” means the load below which a weighing-in-motion result before totalising may be subject to an excessive relative error;

“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;

“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));

“prescribed limits of error” has the meaning set out in regulation 9(3);

“reference wagon” means a railway goods vehicle that is recognised by the automatic rail-weighbridge as a vehicle to be weighed being—

and which has been selected for the purposes of in-motion testing;

“scale interval” or “d” means a value expressed in units of mass for weighing-in-motion that is the difference between—

“scale interval for stationary load” means the scale interval used for static tests;

“the stamp” or “verification mark” means the prescribed stamp M1;

“total train” means a number of coupled wagons whose totalised weight is to be obtained;

“wagon” means a loaded or unloaded railway goods vehicle that is recognised by the automatic rail-weighbridge as a vehicle to be weighed;

“weighing-in-motion” means weighing objects that are in motion; and

“weigh zone” means the zone in which a wagon must be located when it is to be weighed.

(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.
