Polymeric materials, cellular, flexible - Determination of air flow value at constant pressure-drop (ISO 7231:2010)

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.

Weich-elastische Polymerschaumstoffe - Bestimmung der Luftdurchlässigkeit bei konstantem Druck (ISO 7231:2010)

weich-elastischen Polymerschaumstoffen fest.
 Verfahren A, für die herkömmlichen Typen weich-elastischer Polymerschaumstoffe;
 Verfahren B, für alle Arten weich-elastischer Polymerschaumstoffe, jedoch insbesondere für Materialien
mit geringer Luftdurchlässigkeit.
ANMERKUNG 1 Luftdurchlässigkeitswerte können als Anhaltspunkt für den Einfluss von Rezeptur und Herstellungsvariablen
auf die Zellenstruktur verwendet werden.
ANMERKUNG 2 In dieser Internationalen Norm steht der Ausdruck „herkömmlicher Typ weich-elastischer Polymerschaumstoffe“
für Typen, die nicht zum Abdichten geeignet sind.

Matériaux polymères alvéolaires souples - Détermination de l'indice d'écoulement d'air à chute de pression constante (ISO 7231:2010)

L'ISO 7231:2010 spécifie deux méthodes de détermination de l'indice d'écoulement d'air des matériaux polymères alvéolaires souples:
méthode A, pour les matériaux polymères alvéolaires souples classiques;
méthode B, pour tous types de matériaux polymères alvéolaires souples, mais essentiellement pour les matériaux ayant une faible perméabilité à l'air.

Polimerni materiali - Penjeni polimeri - Mehke pene - Določanje vrednosti zračnega pretoka pri konstantni razliki tlakov (ISO 7231:2010)

Ta mednarodni standard določa dve metodi za določanje vrednosti zračnega pretoka mehkih penjenih polimernih materialov: - metoda A za konvencionalne vrste mehkih penjenih polimernih materialov; - metoda B za vse vrste mehkih penjenih polimernih materialov, predvsem pa za materiale z nizko prepustnostjo zraka.
