Polymeric materials, cellular flexible — Determination of air flow permeability

Matériaux polymères alvéolaires souples — Détermination de la perméabilité à l'air

Abstract / scope

Applicable to test pieces cut from products of cellular materials. Useful for two purposes: a) studying the structure of cellular products in connection with their physical properties and their method of manufacture and b) ensuring product quality (quality assurance). Describes principle, apparatus, test piece and conditions, procedure and calculation and expression of the results. Three figures deliver the details for testing.
