Characterization of One Component Foam - Part 3: Application

This document specifies test methods for the evaluation of the application properties for moisture curing, self-curing or water drying foams dispensed from single pressurized containers used as an insulating air sealant and adhesive for both building and non-building applications.
This document does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.
-   The following test methods are described: Cutting Time: This test method describes how to determine the hardening time of a freshly foamed OCF (froth) until it can be cut.
-   Tack Free Time: This test method describes how to determine the tack free time of a freshly foamed OCF.
-   Sagging Behaviour: This test method describes how to evaluate the sagging behaviour and determine the biggest joint possible before a liquid OCF (froth) slips off.

Charakterisierung von Einkomponentenschäumen - Teil 3: Anwendung

Dieses Dokument legt Prüfverfahren für die Beurteilung der Anwendungseigenschaften von feuchtigkeitshärtenden, selbsthärtenden oder wassertrocknenden Schäumen fest, die aus einzelnen druckbeaufschlagten Behältern abgegeben werden und als dämmender Dichtstoff und Klebstoff sowohl für Bauanwendungen als auch andere Anwendungen verwendet werden.
Dieses Dokument beansprucht nicht, sämtliche mit seiner Anwendung verbundenen Sicherheitsprobleme, soweit diese gegeben sind, zu behandeln. Es liegt in der Verantwortung des Anwenders dieser Norm, angemessene Maßnahmen in Bezug auf den Gesundheits  und Arbeitsschutz einzuleiten und die Anwendbarkeit gesetzlicher Anforderungen vor ihrer Anwendung zu ermitteln.
Die folgenden Prüfverfahren werden beschrieben:
-   Zeit bis zur Schnittfestigkeit des Schaums: Dieses Prüfverfahren beschreibt, wie die Härtungszeit eines frisch verschäumten OCF (nicht gehärteter Schaum) zu bestimmen ist, bis er geschnitten werden kann.
-   Zeit bis zur Klebfreiheit: Dieses Prüfverfahren beschreibt, wie die Zeit bis zur Klebfreiheit eines frisch verschäumten OCF zu ermitteln ist.
-   Absinkverhalten: Dieses Prüfverfahren beschreibt, wie das Absinkverhalten zu beurteilen und die größtmögliche Fuge zu ermitteln ist, bevor ein flüssiger (nicht gehärteter) OCF nach unten wegfließt.

Caractérisation des mousses monocomposants - Partie 3 : Application

Le présent document spécifie des méthodes d’essai permettant d’évaluer les caractéristiques d’application des mousses durcissant à l’humidité, des mousses autopolymérisables et des mousses séchant dans l’eau, appliquées à partir de récipients individuels sous pression, utilisées en tant que joint d’étanchéité à l’air et en tant qu’adhésif pour les applications du génie civil et autres.
Le présent document ne prétend pas aborder la totalité des problèmes de sécurité qui pourraient découler de son utilisation. Il est de la responsabilité de l’utilisateur de la présente norme de respecter des pratiques de sécurité et de santé appropriées et de déterminer l’applicabilité des exigences réglementaires avant son utilisation.
Les méthodes d’essai suivantes sont décrites :
-   temps de coupe : cette méthode d’essai permet de déterminer le temps de durcissement d’une mousse monocomposant fraîchement expansée jusqu’à ce qu’elle puisse être découpée ;
-   temps de séchage hors poisse : cette méthode d’essai permet de déterminer le temps de séchage hors poisse d’une mousse monocomposant fraîchement expansée ;
-   tenue à la coulure : cette méthode d’essai permet d’évaluer la tenue à la coulure et de déterminer le plus grand joint possible avant glissement d’une mousse monocomposant liquide.
