ASTM D964

ASTM D964 is a standard test method used to determine the acidity or alkalinity of petroleum products, such as lubricants, fuels, and additives. It measures the amount of acid or base present in the sample by neutralizing it with a standard solution and then calculating the acidity or alkalinity based on the amount of solution used. This test helps assess product quality, stability, and suitability for use, ensuring that the lubricant or fuel won't cause corrosion or damage to machinery. It is an important quality control measure for the petroleum industry.
