30—Determination of mass

        (1)         For the purposes of determining the mass of a vehicle—

            (a)         a weighbridge—

                  (i)         must have a steel or concrete platform or, if a wooden platform, must be verified, re-verified or certified, and marked with an inspector's mark or licensee's mark, in accordance with the Trade Measurement Act 1993 and the regulations under that Act; and

                  (ii)         must be so situated as to have sufficient space for vehicles usually weighed on the weighbridge to be driven or drawn on and off without turning on the platform; and

                  (iii)         must have a level surface so that no point on the surface on which the mass to be measured bears is more than 15 millimetres above or below any other point on that surface; and

                  (iv)         must operate within the appropriate limits of error for that type of weighbridge that may be tolerated under the Trade Measurement Act 1993 ; and

            (b)         in order to determine the mass of a vehicle with or without its load and the mass carried on any two or more axles of a vehicle on a weighbridge, it is not necessary to measure the mass carried on all the relevant axles simultaneously, but the mass may be determined by aggregating the measurements of mass taken separately in relation to the axles in question, provided that in determining the mass carried on a vehicle having an axle group or axle groups, the axles within each group must be measured as a whole; and

            (c)         when an approved instrument for determining mass is used in order to determine the mass of a vehicle with or without its load and the mass carried on any two or more axles of a vehicle, the mass may be determined by aggregating the measurements of mass taken simultaneously or separately in relation to the axles in question, provided that, in determining the mass carried on individual axles of an axle group, all of the axles within that group must be measured simultaneously and must, as far as possible in the circumstances, be in the same plane.

        (2)         In this regulation—

"approved instrument for determining mass" means an instrument for determining mass approved in writing by the Minister for the purposes of this regulation.
