标准编号：ISO 14184-3:2023

中文名称：纺织品 甲醛的测定 第3部分：用液相色谱法测定游离和水解的甲醛（萃取法）

英文名称：Textiles — Determination of formaldehyde — Part 3: Free and hydrolysed formaldehyde (extraction method) by liquid chromatography

发布日期：2023-12

标准范围

该文献规定了一种通过萃取法测定游离甲醛和部分通过水解提取的甲醛的量的方法。该方法可用于纺织纤维、织物或纱线的测试。笔记？该方法基于液相色谱（LC），具有选择性，对有色提取物不敏感，旨在用于甲醛的精确定量。

This document specifies a method for determining the amount of free formaldehyde and formaldehyde extracted partly through hydrolysis by means of an extraction method. The method can be applied for the testing of textile fibres, fabrics or yarns.

NOTE            This method, based on liquid chromatography (LC), is selective and not sensitive to coloured extracts and is intended to be used for precise quantification of formaldehyde.
