Scope
This part of GB/T 11213 specifies the method for determining the sodium hydroxide content in sodium hydroxide for chemical fiber. The sodium hydroxide content is usually expressed in two different ways in terms of the mass fraction of NaOH: w1 —— total alkali content (calculated in terms of NaOH); w2 —— sodium hydroxide content (calculated in terms of NaOH), which is the total alkali content minus the sodium carbonate content.
