Goods of household chemistry. Method for determination of pH
Товары бытовой химии. Метод определения показателя активности водородных ионов (рН)
Status: Not effective - Canceled. Registration information 1811-st dated 11/22/2013 (official site of Rosstandart)
This standard applies to cleaning, bleaching, coupling, deodorizing, stain-removing agents and establishes a method for determining the activity rate of hydrogen ions from 2 to 12 pH. The essence of the method consists in potentiometric measurement of the potential difference between the measuring glass electrode and the reference electrode (auxiliary) immersed in the test medium or aqueous solution or aqueous extract
Настоящий стандарт распространяется на чистящие, отбеливающие, аппретирующие, дезодорирующие, пятновыводящие средства и устанавливает метод определения показателя активности водородных ионов от 2 до 12 рН. Сущность метода заключается в потенциометрическом измерении разности потенциалов измерительного стеклянного электрода и электрода сравнения (вспомогательного), погруженных в испытуемое средство или водный раствор, или водную вытяжку
