Cold protective clothing was studied in 2 European Union projects. The objectives were (a) to examine different insulation calculation methods as measured on a manikin (serial or parallel), for the prediction of cold stress (IREQ); (b) to consider the effects of cold protective clothing on metabolic rate; (c) to evaluate the movement and wind correction of clothing insulation values. Tests were carried out on 8 subjects. The results showed the possibility of incorporating the effect of increases in metabolic rate values due to thick cold protective clothing into the IREQ model. Using the higher thermal insulation value from the serial method in the IREQ prediction, would lead to unacceptable cooling of the users. Thus, only the parallel insulation calculation method in EN 342:2004 should be used. The wind and motion correction equation (No. 2) gave realistic values for total resultant insulation; dynamic testing according to EN 342:2004 may be omitted.
在两个欧盟项目中对防寒服进行了研究。目标是：(a) 研究在人体模型上测量的不同隔热计算方法（串联或并联），以预测冷应激（IREQ）；(b) 考虑防寒服对代谢率的影响；(c) 评估服装隔热值的运动和风速校正。对8名受试者进行了测试。结果表明，有可能将因厚重防寒服导致的代谢率值增加的影响纳入IREQ模型。在IREQ预测中使用串联方法得出的较高隔热值，会导致使用者出现不可接受的体温下降。因此，应仅使用EN 342:2004中的并联隔热计算方法。风速和运动校正方程（第2号）给出了总合成隔热的实际值；根据EN 342:2004进行的动态测试可以省略。
