1 Scope
This standard specifies the test methods for 16 indexes of surface active agent and detergent, i.e. reduced sample, granularity, total phosphorus pentoxide, total active matters, nonionic surface active agents, various forms of phosphate, tosylate, foaming power, chelating agent (EDTA), apparent density, whiteness, moisture and volatile matter, 4A zeolite content, active oxygen, alkali protease activity, and active chlorine.
This standard is applicable to the determination of indexes for surface active agent and detergent. For determining sample using the method specified in this standard, it shall select method as appropriate to the sample.
