“metrological characteristics” means those operational characteristics of a machine which are evaluated during testing of the machine in accordance with the appropriate provisions of regulation 37 of and Schedule 2 to these Regulations;

“multiple weighing” means determining the mass of a load by totalising the results of more than one static weighing operation during each of which the load is only partially supported by the load receptor;

“non-automatic weighing machine” means weighing equipment that includes a machine which accomplishes a weighing operation and which requires the intervention of an operator during the weighing process, especially to deposit loads on, or remove loads from, the load receptor and also to determine the result of the weighing process, and for the purposes of these Regulations shall include an automatic catchweight weighing machine;

“non-self indicating machine” means a machine in which the position of equilibrium is obtained entirely by the intervention of an operator;

“prescribed limits of error” has the meaning set out in regulation 38 below;

“published particulars” means, in relation to an approved pattern, the particulars of the approved pattern which are published under section 12 of the Act;

“range of self indication” means the range within which the position of equilibrium is obtained without the intervention of the operator;

“relieving device” means a device which can prevent forces applied to a load or weight receptor being transmitted to certain delicate bearings;

“rider” means a small poise which can be moved along a graduated bar or beam;

“rounding error” means the difference between the indicated or printed digital value and the result the machine would give if it were analogue;

“scale interval” means the value, expressed in units of measurement of mass, equal to—

(a)

in the case of a machine with an analogue indicating device, the smallest subdivision of the scale; or

(b)

in the case of a machine with a digital indicating or printing device, the smallest difference between two consecutive indicated or printed values;

“self indicating machine” means a machine in which the position of equilibrium is obtained without the intervention of the operator;

“self service weighing machine” means a non-automatic weighing machine which, in accordance with section 7(1) and (4)(a) of the Act, is made available for use for trade by any prospective buyer of goods so that the weight and price of goods selected by him is determined and made known to him;

“semi-self indicating machine” means a machine in which the operator only intervenes above a certain range of self indication or printing, in order to re-establish the function of self indication or printing;

“the stamp” means the prescribed stamp(2);

“subtractive tare device” means a tare device which intrudes on the weighing range of any weight indicating and printing device with which it is associated;

“tare device” means a device for—

resetting the weight indicating and weight printing devices to zero when a load is on the associated load receptor, or

(b)

subtracting a preset value of weight from the weight indicating or printing device;

“vehicle check weighing machine” means a non-automatic weighing machine which, in accordance with section 7(4)(a) of the Act, is made available for use for trade only for the purpose of checking compliance with statutory provisions regarding the weight and axle weight of road vehicles;
