本文件规定了一种测定含有聚氨酯（PU）涂层材料的鞋类和鞋类部件中二甲基甲酰胺（DMF）含量的方法。 注？1？在制鞋业中，当PU被注射（反应成型）时，该工艺不需要使用DMF。对于PU涂层材料，可以使用DMF。 注2:二甲基甲酰胺DMF、DMFa、DMFo可使用几种缩写。本文档使用DMF。 ISO/TR 16178:2021，表1定义了该测定涉及的材料。

This document specifies a method to determine the amounts of dimethylformamide (DMF) in footwear and footwear components containing polyurethane (PU) coated material. NOTE？1？In the footwear industry, when PU is injected (reaction moulded), this process does not require the use of DMF. For PU coated material, the use of DMF is possible. NOTE？2？Several abbreviations can be used for dimethylformamide DMF, DMFa, DMFo. This document uses DMF. ISO/TR 16178:2021, Table？1 defines which materials are concerned by this determination.
