Product Code:SAE J1787
Title:Measurement of the Total Ash Content of Aviation Piston Engine Oils by a Calculation Method
Issuing Committee:E-38, Aviation Piston Engine Fuels And Lubricants
Scope:This SAE Recommended Practice describes an empirical method for determining the theoretical ash content of aviation piston engine lubricating oils by calculating the equivalent weight of metallic oxides formed at 775 °C based on the metallic elemental concentration.The calculation method of ash determination may be used as an alternate to ASTM D 482 for application to the standards for aviation piston engine lubricating oils.【英文标准名称】:Industrialsewingmachines;motorwithclutchforpositiondrive,typetest
