润滑油中机械杂质测定方法的改进

摘要

The method for determination of the mechanical impurities content in lubricating oil by 93#gasoline as solvent instead of benzene or toluene has the accuracy and precision fully meeting the require-ments of GB/T511 -2010,and can avoide the hazard on human body and enviromental caused by the ben-zene and toluene during the operation.%采用93＃汽油代替苯或甲苯作为溶剂测定润滑油中机械杂质含量，精密度及准确度均满足 GB／T511－2010的要求。操作过程中避免了苯及甲苯对人体的危害，消除了环境危害因素。
