Specifications Relating to Non-automatic Weighing Devices (1998) (SI/98-81)

1 (1) The definitions in this section apply in these Specifications.

actual scale interval

actual scale interval or d means the value, expressed in units of mass

• (a) with respect to analogue indications, of the difference between the values corresponding to two consecutive scale marks; and

• (b) with respect to digital indications, the difference between two consecutively indicated values. (échelon réeloud )

automatic indicating device

automatic indicating device means a weighing device in which the position of equilibrium is obtained without an operator’s intervention. (appareil de pesage à équilibre automatique)

auxiliary indicating element

auxiliary indicating element means a rider, a vernier or, in the case of a digital indicating device, the last figure after the decimal sign that is clearly differentiated from other figures such as by size, shape or colour. (dispositif indicateur auxiliaire)

initial zero-setting mechanism

initial zero-setting mechanism means a feature that automatically sets a weighing device to zero at the time the device is switched on and before it is ready for use. (dispositif de mise à zéro initiale)

maximum capacity

maximum capacity or Max means the maximum weighing capacity of a weighing device and, in the case of a multiple range device, the maximum weighing capacity of the relevant range. (portée maximaleouMax )

metrological function

metrological function means a function of a weighing device that is necessary for the measurement process — including the sensing of the measured quantity, the transmission, processing, storage and correction or adjustment of measurement signals or values and the indication or printing of measurement values — and that can impact on the final quantity determination or price calculation or affect the validity of transactions. Metrological functions include, but are not limited to,

• (a) displaying or printing gross, tare, net and negative weight values, zero, and unit and total prices;

• (b) setting zero, linearity, sensitivity, scale intervals, maximum capacity and motion detection; and

• (c) performing the computation and rounding of price and weight values and the storing of values. (fonction métrologique)

module

module means a part of a weighing device that

• (a) performs a specific metrological function;

• (b) can be examined and tested separately; and

• (c) is subject to the error limits set out in these Specifications. (module)

multi-interval device

multi-interval device means a weighing device

• (a) that has a single weighing range divided into partial weighing ranges, each of which has a different scale interval; and

• (b) in which the appropriate partial weighing range is automatically determined according to the load applied, both for increasing and decreasing loads. (appareil à échelons multiples)

multiple range device

multiple range device means a weighing device that

• (a) has, for the same weighing and load-receiving element, two or more weighing ranges, each of which

  • (i) extends from zero to the maximum capacity of the range, and

  • (ii) has a different verification scale interval; and

• (b) selects automatically, or permits the operator to select manually, any of the weighing ranges. (appareil à étendues multiples)

non-automatic indicating device

non-automatic indicating device means a weighing device that requires an operator’s intervention to obtain equilibrium, such as an equal-arm scale with weights. (appareil de pesage à équilibre non automatique)

non-automatic weighing device

non-automatic weighing device or weighing device means a weighing machine that weighs discrete loads and that requires an operator’s intervention during the weighing process, such as to deposit the load to be measured on the weighing and load-receiving element and to remove it therefrom or to obtain weight results. (appareil de pesage à fonctionnement non automatiqueouappareil de pesage )

number of verification scale intervals

number of verification scale intervals means the value obtained by using the following formula:

Max/e

where

Max

represents the maximum capacity, and

e

represents the verification scale interval. (nombre d’échelons de vérification)

on-board weighing system

on-board weighing system means a weighing device designed to be an integral part of, or attached or secured to, the frame, chassis, lifting mechanism or bed of mobile equipment such as a truck, tractor, trailer or forklift. (système de pesage monté sur véhicule)

verification scale interval

verification scale interval or e means a value, specified by the manufacturer and expressed in units of mass, that is used for the classification and inspection of a weighing device. (échelon de vérificationoue )

weight classifier

weight classifier means a weighing device with a digital indicating element that rounds a weight value up to the next verification scale interval. (appareil classificateur)

(2) In these Specifications, a reference to a verification scale interval or actual scale interval refers to that of the weighing range or partial weighing range, as the case may be, that is being tested.
