Protective gloves against dangerous chemicals and micro-organisms - Part 4: Determination of resistance to degradation by chemicals (ISO 374-4:2019)
This document specifies the test method for the determination of the resistance of protective glove materials to Degradation by dangerous chemicals with continuous contact.
Schutzhandschuhe gegen Chemikalien und Mikroorganismen - Teil 4: Bestimmung des Widerstandes gegen Degradation durch Chemikalien (ISO 374-4:2019)
Dieses Dokument 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 Ringversuchen mit diesem Verfahren.
Es ist empfehlenswert, zusätzlich zur Beurteilung des chemischen Widerstands andere Prüfungen wie etwa Widerstand gegen Permeation und Widerstand gegen Penetration zu nutzen, weil die Chemikalienprüfung nicht ausreichend Informationen zu den Veränderungen der physikalischen Eigenschaften, die einen Handschuh während der Beanspruchung durch eine Chemikalie beeinflussen, bietet. Die Oberfläche der Außenseite des Handschuhs muss der Chemikalie ausgesetzt werden.
Gants de protection contre les produits chimiques dangereux et les micro-organismes - Partie 4: Détermination de la résistance à la dégradation par des produits chimiques (ISO 374-4:2019)
Le présent document 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.
Il est préférable que d'autres essais, tels que la résistance à la perméation et la résistance à la pénétration, soient utilisés en plus de l'évaluation de la résistance chimique car l'analyse chimique ne fournit pas 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.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).

INTERNATIONAL STANDARD ISO 374-4:2019(E)
Protective gloves against dangerous chemicals and micro-
organisms —
Part 4:
Determination of resistance to degradation by chemicals
1 Scope
This document 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.
It is preferable that other tests used in addition to the evaluation of chemical resistance such as
permeation resistance and penetration, as the chemical test do 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.
