本标准规定了高分子屋面防水卷材不受浸入化学液体（包括水）影响的试验方法及测定如此处理后性能变化的方法。

Scope

This part of GB/T 328 specifies the test method for the test piece of polymer roofing waterproof membrane not to be affected by immersion in chemical liquid (including water), and the method for measuring the performance change after such treatment. The test only considers the case where the entire surface is immersed in the liquid. This method is applicable to the determination of the following property changes: a) mass change immediately after immersion removal or after immersion removal and drying; b) dimensional change immediately after immersion removal or after immersion removal and drying; c) immediately after immersion removal or after immersion removal and drying Changes in appearance; d) Changes in physical properties immediately after immersion or removal after immersion and drying. When required, test immediately after immersion to determine the effect of maintaining the material in a liquid state. When necessary, test after immersion, take out and dry to determine the effect of material liquid volatilization and removal.
