Popis
BS 4443-7:1992+A1:2008
This standard BS 4443-7:1992+A1:2008 Methods of test for flexible cellular materials is classified in these ICS categories:
- 83.100 Cellular materials
This Part of BS 4443 describes 
the 
method of test that applies to flexible cellular products of polymeric origin: determination of tear strength of flexible materials with an integral skin and a density not greater than 500 kg/m3 and determination of compression set under humid conditions.
NOTE 1 The tear strength method described produces a value that may be regarded as a measure of the tear strength of the skinned foam under the conditions of the particular test.
NOTE 2 The titles of the publications referred to in this standard are listed on the inside back cover.
Gives a procedure for measuring compression set under humid conditions for the first time, as well as updating the conditioning procedure.
