ASTM D501

Sampling and Chemical Analysis of Alkaline Detergents

Applicability: ASTM D501 (specifically ASTM D501-03, reapproved 2023) provides standardized procedures for sampling and chemically analyzing inorganic alkaline detergents. Its primary applicability is determining properties like total alkalinity, water-insoluble matter, density, and pH for products such as caustic soda, soda ash, borax, and phosphates.

Purpose: ASTM D501 outlines standard procedures for sampling and chemically analyzing inorganic alkaline detergents, such as caustic soda, soda ash, and borax. It is used to determine key quality properties including total alkalinity, water-insoluble matter, pH, and density, ensuring consistency and quality control for industrial cleaning agents.
