英文名称：Thermal insulating products for building applications — Determination of long-term water absorption by diffusion
发布日期：2019-06
标准范围
This document specifies the equipment and procedures for determining the long-term water absorption
of test specimens by diffusion. It is applicable to thermal insulating products. It is intended to simulate
the water absorption of products subjected to high relative humidities, approximating to 100 %, on
both sides and subjected to a water vapour pressure gradient for a long period of time e.g. inverted roof
or unprotected ground insulation.
The test is not applicable for all types of thermal insulating products. The relevant product standard
should state for which of its products, if any, this test is applicable.
NOTE For unprotected ground insulation the temperature of 50 °C could be replaced by a lower temperature, when more data is available.
