石油产品、润滑油和添加剂中水含量的测定 卡尔费休库仑滴定法
Application Summary AI generated
This standard specifies the coulometric Karl Fischer titration method for determining trace water content in petroleum products, lubricating oils, and additives. It is applied in quality control and testing laboratories within the petroleum and lubricant industries to ensure product performance and stability by accurately measuring water levels down to parts per million. The method is particularly relevant for assessing moisture in transformer oils, hydraulic fluids, and industrial lubricants where water contamination can degrade properties.
