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 gilt 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 gilt 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, flüssigen Spray-Partikeln ausgesetzt zu sein.
Dieses Dokument gilt nicht 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 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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by Technical Committee ISO/TC 94, Personal safety — Protective
clothing and equipment, Subcommittee SC 13, Protective clothing, in collaboration with the European
Committee for Standardization, (CEN) Technical Committee CEN/TC 162, Protective clothing including
hand and arm protection and lifejackets, in accordance with the Agreement on technical cooperation
between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 17491-4:2008), which has been
technically revised.
The main changes compared to the previous edition are as follows:
— specifications for test liquid have been revised/added;
— clause 6 Apparatus and test subjects has been revised to provide more specificity. Specification
have been changed and/or revised for absorbent overall, calibrated stain, turntable, spray booth,
spray boom, hydraulic nozzles in Clause 6 and other applicable clauses;
— details for the selection of the right overall size have been added in sub-clause 6.10 as well as in
Annex B;
— sub-clause 8.3 has been revised and heading changed to “Distribution of the spray liquid and
alignment of spray nozzles.”;
— figure and additional information have been added in sub-clause 9.1 to provide more specificity;
— inclusion of Annex A on absorbent fabric for the detector suit and non-absorbent fabric for the
calibration pattern;
— inclusion of Annex B on test subject size measurement and right overall size fitting;
— inclusion of Annex C on right donning and doffing, as well as stain area measurement;
— inclusion of Annex D
