标准范围

ISO 1663:2007规定了测定硬质泡沫塑料的水蒸气透过率、水蒸气透过率、水蒸气透过率和水蒸气扩散阻力指数的方法。该方法的范围提供了刚性多孔材料的测试，所述刚性多孔材料具有10mm以上的厚度，并且作为材料的组成部分，其可以包含一些不同材料的天然表皮或粘合饰面。提供了三组不同的温度和湿度条件，如下所示:38℃，试样上的相对湿度梯度为0%至88%；23℃，试样上的相对湿度梯度为0%至85%；23℃，试样之间的相对湿度梯度为0%至50%。通过该方法获得的结果适用于设计目的和生产控制，并包含在产品规格中。该方法适用于水蒸气透过率在3ng/(m2.s)至200ng/(m2.s)范围内的材料。

ISO 1663:2007 specifies a method of determining the water vapour transmission rate, water vapour permeance, water vapour permeability and water vapour diffusion resistance index for rigid cellular plastics.The scope of this method provides for the testing of rigid cellular materials that have thicknesses from 10 mm upwards and which may, as an integral part of the material, contain natural skins or adhered facings of some different material.Three different sets of temperature and humidity conditions are provided, as follows:

1. 38 °C and a relative-humidity gradient across the test specimen of 0 % to 88 %;
2. 23 °C and a relative-humidity gradient across the test specimen of 0 % to 85 %;
3. 23 °C and a relative-humidity gradient across the test specimen of 0 % to of 50 %.

The results obtained by this method are suitable for design purposes and production control, and for inclusion in product specifications.The method is suitable for materials which have water vapour transmission rates in the range 3 ng/(m².s) to 200 ng/(m².s).
