Scope
Main technical content: According to the provisions of RB/T 214-2017 "Evaluation of the Competence of Inspection and Testing Organizations - General Requirements for Inspection and Testing Organizations", motor vehicle inspection organizations, as inspection and testing organizations, should establish and maintain procedures for assessing the measurement uncertainty as needed. In practical applications, motor vehicle inspection organizations need to conduct uncertainty assessments when verifying testing equipment, controlling and analyzing the quality of testing results, conducting inter-laboratory comparisons, capability verification, measurement audits, and comparing equipment and personnel within the laboratory. This document is based on GB 3847-2018 "Limit Values for Diesel Vehicle Pollutant Emissions and Measurement Methods (Free Acceleration Method and Loaded Deceleration Method)", GB 18285-2018 "Limit Values for Gasoline Vehicle Pollutant Emissions and Measurement Methods (Double Idling Method and Simplified Operating Condition Method)", and GB 38900-2020 "Items and Methods for Motor Vehicle Safety Technical Inspection", and is compiled with reference to CNAS-GL023:2018 "Guidelines and Examples for Measurement Uncertainty Evaluation of Typical Parameters in the Field of Automobile and Motorcycle Inspection". It aims to provide guidance for motor vehicle inspection organizations in conducting uncertainty assessments of testing results and provide examples of some testing result assessments.
