ActivePetroleum products--Determination of saponification number
石油产品皂化值测定法
Application Summary AI generated
This standard specifies a test method for determining the saponification number of petroleum products, which measures the amount of potassium hydroxide required to saponify the fatty esters and neutralize the free acids in a sample. It is applied in the quality control and specification testing of lubricating oils, transformer oils, and other petroleum-based products within the petroleum industry. The method is used to assess the presence of saponifiable components, such as synthetic esters or animal/vegetable oil contaminants, in these products.
