Protective gloves against chemicals and micro-organisms - Part 4: Determination of resistance to degradation by chemicals

This European Standard specifies the test method for the determination of the resistance of protective glove materials to degradation by dangerous chemicals with continuous contact.
NOTE   Annex A gives information on interlaboratory test results on this method.
Other tests used to evaluate chemical resistance such as permeation resistance and penetration resistance may not provide sufficient information on the physical property changes affecting a glove during exposure to a chemical. It is necessary that the outside surface of the glove be exposed to the chemical.

Schutzhandschuhe gegen Chemikalien und Mikroorganismen - Teil 4: Bestimmung des Widerstandes gegen Degradation durch Chemikalien

Diese Europäische Norm legt das Prüfverfahren für die Bestimmung des Widerstands von Werkstoffen für Schutzhandschuhe gegen Degradation durch gefährliche Chemikalien bei ständigem Kontakt fest.
ANMERKUNG   Anhang A enthält Informationen zu den Ergebnissen aus Labor-Ringprüfungen mit diesem Verfahren.
Andere Prüfungen zur Beurteilung des chemischen Widerstands wie etwa Widerstand gegen Permeation und Widerstand gegen Penetration geben möglicherweise nicht ausreichend Informationen zu den Veränderungen der physikalischen Eigenschaften, die einen Handschuh während der Beanspruchung durch eine Chemikalie betreffen. Die Außenseite des Handschuhs muss der Chemikalie ausgesetzt werden.

Gants de protection contre les produits chimiques et les micro-organismes - Partie 4: Détermination de la résistance à la dégradation par des produits chimiques

La présente Norme européenne spécifie la méthode d’essai pour la détermination de la résistance des matériaux des gants de protection à la dégradation par contact continu avec des produits chimiques dangereux.
NOTE   L’Annexe A donne des informations sur les résultats de l’essai interlaboratoires sur cette méthode.
Les autres essais utilisés pour évaluer la résistance chimique telle que la résistance à la perméation et la résistance à la pénétration peuvent ne pas fournir suffisamment d’informations sur les changements de propriétés physiques affectant un gant lors d’une exposition à un produit chimique. Il est nécessaire que la surface extérieure du gant soit exposée au produit chimique.
