Scope

This Part of GB/T 21296 specifies the terms and definitions, composition, classification
and designation, measurement requirements, technical requirements, layout
requirements, installation condition and maintenance requirements, WIM system
function and data requirements, test methods, inspection rules, as well as marking,
packaging, transportation, and storage of bending-plate-type automatic instruments for
weighing road vehicles in motion (hereinafter referred to as bending-plate-type
dynamic vehicle weighing instruments).
This Part applies to the combination of multiple bending plate sensors installed in the
weighing control area in a way of embedding in and flushing with the road surface
during the dynamic driving of road vehicles; automatic weighing instruments and
systems that measure vehicle wheel loads (if applicable), axle loads, axle-group loads
(if applicable) and obtain whole loads. The bending-plate-type automatic instruments
for weighing vehicles in motion without weighing control area may refer to it for
implementation.
This Part does not apply to weighing instruments that set the single-sided bending plate
sensor to measure only the wheel load on one side, and then obtain the axle load, axle-
group load, and the whole load by multiplying.

Summary	This standard specifies the terms and definitions, composition, classification and naming, measurement requirements, technical requirements, layout requirements, installation conditions and maintenance requirements, WIM system functions, and functions of curved plate dynamic road vehicle automatic weighing instruments (hereinafter referred to as curved plate dynamic truck scales). Data requirements, test methods, inspection rules, as well as marking, packaging, transportation and storage, etc. This standard is applicable to the combination of multiple bent plate sensors embedded in the road surface and installed flush with the road surface in the weighing control area during the dynamic driving of road vehicles to measure vehicle wheel load (if applicable), axle load, and axle group Load (if applicable), and automatic weighing instruments and systems to obtain the total weight of the vehicle. The bending plate type dynamic vehicle automatic weighing instrument without weighing control zone can be implemented by reference. This standard does not apply to setting unilateral bends
