T/FJSJLXH 001-2023 Active

Scope: This document is applicable to the calibration, in-use verification, and quality control of the display error of electronic vehicle scales with accuracy grades of (50~150)t and ordinary accuracy grades. Other electronic vehicle scales can be used for reference. Main technical content: This standard proposes a scientific, efficient, and accurate calibration method for the first time. Using M1 or M12 class weights of about 20 tons as standard instruments, and using the enterprise's empty and loaded vehicles as "substitutes", as well as 3-ton forklifts as auxiliary equipment, it can quickly and accurately calibrate and verify the display errors of various weighing points (500 e, 2000 e, 50% of the maximum weighing capacity, and higher) of (50~150)t electronic vehicle scales, with each taking only about 3 hours. From March to July 2023, on-site tests were conducted in four large and medium-sized enterprises, which fully met the requirements of the inspection regulations and the actual needs of enterprises. It can solve the long-standing problem of difficulty in finding substitutes for large-tonnage vehicle scale calibration and long calibration time, which has significant socio-economic benefits and wide application value.
