本文件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。本方法适用于厚度为10？mm向上，并且作为材料的一个组成部分，可以包含一些不同材料的天然蒙皮或粘合饰面。提供了三组不同的温度和湿度条件，如下所示:A）？38？°C，试样上的相对湿度梯度为0？%到88？%b）？23？°C，试样上的相对湿度梯度为0？%到85？%c）？23？°C，试样上的相对湿度梯度为0？%到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3？μ g/(m2？s)至1？400？微克/（m2？s）。

This document 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.

This method is applicable for the testing of rigid cellular materials that have thicknesses from 10 mm upwards and can, 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:

a)       38 °C and a relative-humidity gradient across the test specimen of 0 % to 88 %

b)       23 °C and a relative-humidity gradient across the test specimen of 0 % to 85 %

c)        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 μg/(m²？s) to 1 400 μg/(m²？s).
