regulation 5(b)
Instruments shall comply with the appropriate metrological and technical requirements at temperatures from −10°C to +40°C. However, for special applications the limits of the temperature range may differ from those given above but such a range shall not be less than 30°C and shall be specified in the descriptive markings as set out in Schedule 4.
Where a filling instrument is marked with a temperature range, it shall not be used for trade in temperatures outside that range.
Instruments which are not intended for installation in a fixed position and which do not have a level indicator shall comply with the appropriate metrological and technical requirements when tilted by 5%.
Where a level indicator is present it shall enable the instrument to be set to a tilt of 1% or less.
A filling instrument shall be designed to suit the method of operation and the products for which it is intended. It shall be of adequately robust construction so that it maintains its metrological characteristics.
Non-automatic or semi-automatic zero-setting and tare devices must be locked during automatic operation.
The weighing unit shall be in stable equilibrium when the zero-setting and tare devices are being set.
Where a filling instrument is marked (in accordance with Schedule 4) with a mark which signifies the purpose or manner of use, it shall not be used for a purpose or in a manner which does not accord with that marking.
A filling instrument shall only be used for trade for the purpose of weighing material the values of which, expressed in units of measurement of mass, are neither less than the value of the minimum capacity nor more than the value of the maximum capacity.
