一、提出问题1.检定标准器砝码的数量问题JJG539-1997《数字指示秤检定规程》中要求的称量测试、重复性测试、除皮测试、鉴别力测试都需要测试最大秤量点,要求检定部门至少配置最大秤量一半的标准砝码。但是有些县级乃至市级检定机构仅拥有20kg标准砝码,其总量为5t~10t左右,有些检定机构有1000kg的大质量砝码,但数量有限,距离JJG539-1997要求检定电子汽车衡所要求的砝码数量还有很大差距。
First, ask questions 1. Test the number of standard weights JJG539-1997 “Digital Indicator Scale test procedures,” the required weighing test, repeatability test, skinning test, discrimination test needs to test the maximum weighing point requirements The verification department should configure at least half the standard weight of the maximum capacity. However, some county-level and municipal-level certification bodies only have 20kg standard weights, the total amount of which is about 5t ~ 10t. Some test institutions have a mass weight of 1000kg, but the number is limited. The distance required by JJG539-1997 for testing electronic truck scale The amount of weight required is still a big gap.
