GOST 32385-2013

ГОСТ 32385-2013

Goods of household chemistry. Method for determination of pH

Товары бытовой химии. Метод определения показателя активности водородных ионов (рН)

Status: Effective - Introduced for the first time. IUS 11-2014

This standard applies to household products (hereinafter - the means) in the form of liquids, including thickened, powders, suspensions, pastes and sets the method for determining the activity of hydrogen ions in the range from 0 to 14 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 substance or its aqueous solution or aqueous extract.

Настоящий стандарт распространяется на товары бытовой химии (далее - средства) в виде жидкостей, в том числе загущенных, порошков, суспензий, паст и устанавливает метод определения показателя активности водородных ионов в диапазоне от 0 до 14 рН. Сущность метода заключается в потенциометрическом измерении разности потенциалов между измерительным стеклянным электродом и электродом сравнения (вспомогательным), погруженными в испытуемое средство или его водный раствор, или водную вытяжку
