人造革合成革試驗方法

游離異氰酸酯含量的測定

警示─使用本文件的人員應有正規(guī)實驗室工作的實踐經(jīng)驗。異氰酸酯屬于危險化學品第6.1類毒害

物，操作時應佩戴防護手套、防護眼鏡和呼吸防護器具。本文件并未指出所有可能的安全問題，使用者

有責任采取必要的安全和健康措施，并保證符合國家有關(guān)規(guī)定的條件。

1范圍

本文件描述了測定人造革與合成革中游離異氰酸酯含量試驗的液相色譜法（LC法）、氣相色譜?質(zhì)

譜法（GC?MS法）和氣相色譜法（GC法）三種試驗方法。

本文件適用于聚氨酯人造革與合成革中游離異氰酸酯（1，4?亞苯基異氰酸酯、甲苯二異氰酸酯、

六亞甲基二異氰酸酯、三甲基六亞甲基二異氰酸酯、異佛尓酮二異氰酸酯、二苯甲烷二異氰酸酯）含量

的測定。其他的異氰酸酯（如二環(huán)己基甲烷二異氰酸酯）也適用本文件。

2規(guī)范性引用文件
