DIN EN ISO 2870-2009 表面活性剂,洗涤剂.酸性条件下可水解的和不可水解的阴离子活性物质的测定(ISO 2870:2009),DIN EN ISO 2870:2009-07的英文版本
Surface active agents - Detergents - Determination of anionic-active matter hydrolysable and non-hydrolysable under acid conditions (ISO 2870:2009); English version of DIN EN ISO 2870:2009-07
This International Standard specifies a method for the determination, in detergents, of anionic-active matter
hydrolyzable and non-hydrolyzable under acid conditions.
This active matter includes alkyl sulfates and hydroxysulfates and alkylphenol and fatty alcohol ethoxysulfates.
The mean relative molecular mass of the two types of active matter must be known or previously determined,
if their content is expressed as a percentage by mass. If the detergent contains any oxidizing agent, this must
be destroyed before the hydrolysis.
