国家公斤原器是我国唯一的最高的质量实物基准 ,若使用国家公斤原器 ,就避免不了正常磨损 ,使用次数越多 ,磨损越多 ,从而不易保存质量量值。为减少国家公斤原器的使用次数 ,在质量检定系统中 ,设置了国家公斤副基准砝码 ,通过它把质量量值传递给工作基准砝码。国家公斤副基准 National kilograms of the original is the only high quality physical benchmark in China, if the use of national kilograms of the original, we can not avoid the normal wear and tear, the more the number of use, the more wear and tear, and thus not easy to save the quality of the value. In order to reduce the number of national kilograms of the original use, in the quality test system, set the national standard of reference weight kg, through which the quality of the value passed to the working reference weight.
