摘要
对GB4472-1984比重瓶法测定管道防腐用环氧粉末密度测量结果的影响因素进行了分析,并依据JJF1059-1999对比重瓶法测量环氧粉末密度的不确定度进行了评估,当环氧粉末密度为1.595g/cm3时,测量结果的扩展不确定度为0.026g/cm3,k=2。
The influence factors to density measurement of epoxy powder used for pipe corrosion resistanting by GB 4472-1984 pycnometer method were analyzed.The uncertainty of the measurement were evaluated in terms of JJF 1059-1999.When the density of epoxy powder was 1.595 g/cm3,the expanded uncertainty was 0.026 g/cm3(k=2).
