SDO: ISO: International Organization for Standardization
DOD Adopted ANSI Approved Approved
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.
NOTE 1 Air flow values can be used to give an indication of the effects of formulation and production variables on the cellular structure.
NOTE 2 In this International Standard, the expression "conventional type of flexible cellular polymeric material" means types which are unsuitable for sealing purposes.
