Protective clothing - Test methods for clothing providing protection against chemicals - Part 4: Determination of resistance to penetration by a spray of liquid (spray test) (ISO 17491-4:2024)

This document specifies the test method for determining the resistance of chemical protective clothing to penetration by sprays of liquid chemicals at two different levels of intensity:
a)       Method A: low-level spray test. This is applicable to clothing that covers the full body surface and is intended to be worn when there is a potential risk of exposure to small quantities of spray or accidental low-volume splashes of a liquid chemical.
b)       Method B: high-level spray test. This is applicable to clothing with spray-tight connections between different parts of the clothing and, if applicable, between the clothing and other items of personal protective equipment, which covers the full body surface and which is intended to be worn when there is a risk of exposure to sprayed liquid chemical.
This document does not apply to chemical permeation resistance of the materials from which the chemical protective clothing is made.

Schutzkleidung - Prüfverfahren für Chemikalienschutzkleidung - Teil 4: Bestimmung der Beständigkeit gegen das Durchdringen von Flüssigkeitsspray (Spray-Test) (ISO 17491-4:2024)

Dieses Dokument legt Prüfverfahren zur Bestimmung der Beständigkeit von Chemikalienschutzkleidung gegen das Durchdringen von Sprays aus flüssigen Chemikalien in zwei verschiedenen Intensitätsstufen fest:
a)   Verfahren A: Spray-Test mit geringer Intensität. Dieser Test ist anwendbar für Kleidung, die die gesamte Körperoberfläche bedeckt und für das Tragen unter Bedingungen vorgesehen ist, bei denen ein mögliches Risiko besteht, geringen Mengen eines Sprays oder einem geringen Volumen von zufälligen Spritzern einer flüssigen Chemikalie ausgesetzt zu sein.
b)   Verfahren B: Spray-Test mit hoher Intensität. Dieser Test ist anwendbar für Kleidung mit spraydichten Verbindungen zwischen verschiedenen Teilen der Kleidung und, sofern zutreffend, zwischen der Kleidung und anderen Gegenständen persönlicher Schutzausrüstung, die die gesamte Körperfläche bedeckt und für das Tragen unter Bedingungen vorgesehen ist, bei denen das Risiko besteht, gesprühter flüssiger Chemikalie ausgesetzt zu sein.
Dieses Dokument ist nicht anwendbar für die Beständigkeit der Materialien, aus denen die Chemikalienschutzkleidung hergestellt ist, gegen eine Durchdringung von Chemikalien.
ACHTUNG — Einige der in diesem Dokument festgelegten Verfahren umfassen Verfahrensschritte, die zu Gefährdungssituationen führen könnten, daher sollten angemessene Vorsichtsmaßnahmen getroffen werden.

Habillement de protection - Méthodes d’essai pour les vêtements fournissant une protection contre les produits chimiques - Partie 4: Détermination de la résistance à la pénétration par pulvérisation de liquide (essai au brouillard) (ISO 17491-4:2024)

Le présent document spécifie la méthode d’essai pour la détermination de la résistance des vêtements de protection à la pénétration par brouillard de produits chimiques liquides à deux niveaux différents d’intensité:
a)       méthode A: essai au brouillard de faible intensité. L’essai au brouillard de faible niveau s’applique aux vêtements qui couvrent l’intégralité du corps, prévus pour être portés dans des conditions qui présentent un risque d’exposition à de faibles quantités d’un produit chimique liquide projetées sous forme d’un brouillard ou à des projections accidentelles de faibles volumes d’un produit chimique liquide;
b)       méthode B: essai au brouillard d’intensité élevée. L’essai au brouillard de niveau élevé s’applique aux vêtements munis de coutures étanches au brouillard entre les différentes parties du vêtement et, le cas échéant, entre le vêtement et les autres équipements de protection individuelle, qui couvrent l’intégralité du corps et prévus pour être portés dans des conditions qui présentent un risque d’exposition à des produits chimiques liquides pulvérisés.
Le présent document ne s’applique pas à la résistance à la perméation chimique des matériaux de fabrication du vêtement.

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
