This International Standard specifies two methods for determining the air flow value of flexible cellular polymeric materials:
-
method A, for conventional types of flexible cellular polymeric material;
-
method B, for all types of flexible cellular polymeric material, but especially for materials with a low permeability to air.
NOTE1 Air flow values can be used to give an indication of the effects of formulation and production variables on the cellular structure.
NOTE2 In this International Standard, the expression “conventional type of flexible cellular polymeric material” means types which are unsuitable for sealing purposes.
