DESCRIPTION
BS ISO 20852:2020
This standard BS ISO 20852:2020 Textiles. Determination of the total heat transfer through textiles in simulated environments is classified in these ICS categories:
- 59.080.01 Textiles in general
This document specifies the test method for determining the amount of heat transferred through clothing fabrics by the combined dry and evaporative heat emission under simulated and specified conditions. This test method can be used for fabrics, films, coatings, foams and leathers including multilayer assemblies used in hot environment or in activities.
The application of this measurement technique is restricted to a maximum amount of total heat transfer which depend on the dimensions and construction of the apparatus used (e.g. about 1 200 W/m2 for the maximum specifications of the equipment according to ISO 11092).
