1.目的和范围1。1本试验方法测定水溶液中过氧化氢（H2O2）的浓度，尤其是用于纺织品漂白的水溶液。2.原则2。1试样用硫酸酸化，并用标准高锰酸钾溶液滴定。过氧化氢的浓度是使用高锰酸盐溶液的体积和正常浓度来计算的。

1. Purpose and Scope1.1 This test method determines the concentration of hydrogen peroxide (H2O2) in aqueous solutions, particularly those used in textile bleaching.2. Principle2.1 A specimen is acidified with sulfuric acid and titrated with standardized potassium permanganate solution. The concentration of hydrogen peroxide is calculated using the volume and normality of the permanganate solution used.
