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.
