ASTM D501-03(2023)

Die Annotation des Normtextes ASTM D501-03(2023) :

These test methods cover procedures for the sampling and chemical analysis of inorganic alkaline detergents. These detergents include caustic soda, soda ash, modified soda (sequicarbonate type), sodium bicarbonate, sodium metasilicate, trisodium phosphate, tetrasodium pyrophosphate, borax, and sodium triphosphate. Different tests shall be conducted in order to determine the following properties of the detergents: total alkalinity, matter insoluble in water content, apparent density, ignition loss, pH level, turbidity, temperature rise, and particle size. Chemical analysis of the samples shall be performed by using either reverse-flow ion-exchange chromatography or paper chromatography.
