Polymeric materials, cellular, flexible - Determination of air flow value at constant pressure-drop

DS/EN ISO 7231-2010 发布历史

This International Standard specifies two methods for determining the air flow value of cellular polymeric flexible 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 lowpermeability 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.
