玻璃浮计是用于测量液体密度的基础计量器具,它的正确检定对于密度单位的量值传递与溯源十分重要。笔者从事玻璃浮计检定工作多年,将JJG 42—2011规程内容与实际工作经验结合,从多个方面对工作玻璃浮计检定时需要注意的事项进行了总结,以供同行参考。 Glass float is the basic measuring instrument used to measure the density of liquids, and its correct verification is very important for the mass transfer and traceability of density units. The author engaged in glass float test for many years, the contents of the JJG 42-2011 procedures combined with the actual work experience, from many aspects of the work of glass float check need to pay attention to the matters were summarized for peer reference.
