Scope
This standard specifies the method for determining the sulfate content in sodium hydroxide used for chemical fiber production. In this standard, Method A is applicable to products with a sulfate content (calculated as Na2SO4) of 0.001% to 0.07% in sodium hydroxide; Method B is applicable to products with a sulfate content (calculated as Na2SO4) equal to or greater than 0.01% in sodium hydroxide.
