Weich-elastische Polymerschaumstoffe - Bestimmung der Luftdurchlässigkeit bei konstantem Druck (ISO 7231:2010); Deutsche Fassung EN ISO 7231:2010
Overview
This document (EN ISO 7231:2010) has been prepared by Technical Committee ISO/TC 45 "Rubber and rubber products", in collaboration with Technical Committee CEN/TC 249 "Plastics", the secretariat of which is held by NBN. The responsible Committee is NA 062-04-37 AA "Prüfung weich-elastischer Schaumstoffe" ("Testing of flexible cellular polymeric materials") of the Materials Testing Standards Committee. This document specifies two methods for determining the air flow (values) 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.
