建筑应用的绝热产品 - 抗冻融性的测定

[中文适用范围]： 本文件规定了确定从-20℃干燥条件到20℃潮湿条件连续循环对隔热产品机械性能和含水量影响的设备和测试方法。 本文件旨在模拟经常暴露在水和低温条件下的隔热产品的冻融效应，例如倒置的屋顶和无保护的地面隔热材料。 [外文原描述]： This document specifies the equipment and test method for determining the effects of successive cycling from dry conditions at −20 °C to wet conditions at 20 °C on the mechanical properties and moisture content of thermal insulating products. This document is intended to simulate the freeze?thaw effects on thermal insulating products which are frequently exposed to water and low temperature conditions, e.g. inverted roofs and unprotected ground insulation.
