Water. Methods for determination of colour
Вода. Методы определения цветности
Status: Effective - Introduced for the first time. IUS 3-2013
This standard applies to drinking, including packaged, and natural (surface and groundwater) water, including water from drinking water sources, and establishes the following methods for determining the color of water: - A method for visual determination of color (method A) The method is used only if necessary approximate assessment of color; - method of photometric determination of color (method B) using chromo-cobalt or platinum-cobalt scales. The methods for determining color according to this standard are not used for the analysis of water containing admixtures of dyes or other colored chemicals.
Настоящий стандарт распространяется на питьевую, в том числе расфасованную в емкости, и природную (поверхностную и подземную) воду, в том числе воду источников питьевого водоснабжения, и устанавливает следующие методы определения цветности воды: - метод визуального определения цветности (метод А). Метод применяют только при необходимости ориентировочной оценки цветности; - метод фотометрического определения цветности (метод Б) с применением хром-кобальтовой или платино-кобальтовой шкал. Методы определения цветности по настоящему стандарту не применяют для анализа воды, содержащей примеси красителей или иных окрашенных химических веществ
