GB/T 21296.1-2020 Automatic instruments for weighing road vehicles in motion—Part 1:General technical specification

Scope

This part of GB/T 21296 specifies the terms and definitions, classification and naming, metrological requirements, general technical requirements, production and installation requirements, installation conditions and general maintenance requirements, WIM system functions and data requirements, test methods, inspection rules, and requirements for marking, packaging, transportation, and storage for dynamic highway vehicle automatic weighbridges (hereinafter referred to as WIM weighbridges).
This part is applicable to legal and general applications of WIM weighbridges.
This part is applicable to WIM weighbridges or systems installed in weighing control areas and used to obtain the axle loads of highway vehicles (which can be directly measured or obtained by summing the separately measured wheel loads), axle group loads, and vehicle masses by the principle of gravity, regardless of their specific product structures and technical implementation methods. Dynamic vehicle automatic weighbridges without weighing control areas can refer to this part.
This part is not applicable to weighbridges or measurement systems where the carrier or measurement device does not move relative to the vehicle in the horizontal direction during measurement. Such as static wheel load gauges, load measurement devices embedded in vehicle components, etc.
This part is not applicable to weighbridges or measurement systems that cannot ensure that all tires of the measured vehicle are approximately located on the same plane as the surface of the carrier during weighing (such as products and systems that simply place the carrier on the road surface).
This part is not applicable to weighbridges that only measure single-side wheel loads and then obtain axle loads, axle group loads, and vehicle masses by multiplying them by a factor.
