Textiles - Industrial washing and finishing procedures for testing of workwear (ISO 15797:2002)
ISO 15797 specifies test procedures and equipment which can be used in the evaluation of cotton, polyester/cotton and reverse blend workwear intended to be industrially laundered. They serve as a basis for testing relevant properties such as dimensional stability, colour fastness, creasing and seam puckering. This International Standard does not provide instructions and specifications for the procedures and equipment to be used by industrial launderers.
Since it is not possible, in practice, to reproduce industrial laundry processes (washing and finishing) in a laboratory setting, ISO 15797 provides an approach using defined intermediate scale equipment and exacting test procedures which may be used for the evaluation of workwear intended to be laundered industrially.
The methods described in this International Standard simulate the effect of industrial laundering on workwear. Provision is made for eight different washing procedures based on the use of a front- or side-loading horizontal rotating drum type washer/extractor. Each washing procedure is considered to represent a single industrial wash.
ISO 15797 also specifies two drying/finishing test procedures, namely tumble drying and tunnel/cabinet finishing.
Textilien - Industrielles Wasch- und Finishverfahren zur Prüfung von Arbeitskleidung (ISO 15797:2002)
1.1 Diese Internationale Norm legt die Prüfverfahren und Geräte fest, die zur Beurteilung von für das industrielle Waschen vorgesehener Arbeitskleidung aus Baumwolle, und unterschiedlicher Polyester/Baumwolle-Mischungen verwendet werden können. Sie dienen als eine Grundlage zur Prüfung entsprechender Eigenschaften, wie z. B. Formbeständigkeit, Farbechtheit, Knitterbildung und fehlerhafte Nahtkräuselung.
1.2 Diese Internationale Norm enthält keine Anweisungen und Festlegungen bezüglich Verfahren und Maschinen für die industrielle Wäsche.
1.3 Da es in der Praxis nicht möglich ist, Industriewaschverfahren (Waschen und Finishen) in einem Laboraufbau wiederzugeben, liefert diese Internationale Norm einen Ansatz unter Verwendung einer festgelegten Versuchs-Einrichtung mittlerer Größe und genau spezifizierter Prüfverfahren, um die Beurteilung von industriell zu waschender Arbeitskleidung durchführen zu können.
1.4 Das Prüfen der Arbeitskleidung in der tatsächlichen Industriewascheinrichtung und mit den zum Einsatz vorgesehenen Verfahren wird empfohlen, wenn die Vereinbarkeit von Produkt und Waschverfahren abschließend zu beurteilen ist.
Textiles - Méthodes de blanchissage et de finition industriels pour les essais des vetements de travail (ISO 15797:2002)
L'ISO 15797 spécifie des modes opératoires et un équipement qui peuvent être utilisés lors de l'évaluation des vêtements de travail en coton, polyester/coton et mélange inverse devant faire l'objet d'un blanchissage industriel. Elle sert de base pour soumettre à essai des propriétés intéressantes telles que la stabilité dimensionnelle, la solidité des teintures, le froissement et la formation de faux plis. L'ISO 15797 ne fournit ni instructions ni spécifications relatives aux méthodes et à l'équipement que les blanchisseries industrielles doivent utiliser.
Puisqu'il n'est pratiquement pas possible de reproduire en montage de laboratoire les cycles de blanchisserie industrielle (lavage et finition), l'ISO 15797 fournit une approche faisant appel à un équipement de capacité intermédiaire définie et à des méthodes d'essai rigoureuses qui peuvent être utilisés pour l'évaluation des vêtements de travail destinés à faire l'objet d'un blanchissage industriel.
Les méthodes décrites dans l'ISO 15797 simulent les effets d'un blanchissage industriel sur les vêtements de travail. Des dispositions sont prévues pour huit programmes de lavage différents, reposant sur l'utilisation d'une laveuse-essoreuse à tambour horizontal à chargement frontal ou latéral. Il est considéré que chaque programme de lavage représente un lavage industriel simple.
L'ISO 15797 spécifie également deux méthodes d'essai de séchage/finition, à savoir le séchage au tambour, et la finition en tunnel/armoire.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 15797 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 2,
Cleansing, finishing and water resistance tests.
Annex A forms a normative part of this International Standard.

Introduction
The methods described in this International Standard simulate the effect of industrial laundering on workwear.
Provision is made for eight different washing procedures based on the use of a front- or side-loading horizontal
rotating drum type washer/extractor.
Each washing procedure is considered to represent a single industrial wash.
This International Standard also specifies two drying/finishing test procedures:
a) Tumble drying
b) Tunnel/cabinet finishing
A complete laundering test consists of a washing and a drying/finishing procedure.

Textiles — Industrial washing and finishing procedures for testing
of workwear
1 Scope
1.1 This International Standard specifies test procedures and equipment which can be used in the evaluation of
cotton, polyester/cotton and reverse blend workwear intended to be industrially laundered. They serve as a basis for
testing relevant properties such as e.g. dimensional stability, colour fastness, creasing and seam puckering.
1.2 This International Standard does not provide instructions and specifications for the procedures and equipment
to be used by industrial launderers.
1.3 Since it is not possible, in practice, to reproduce industrial laundry processes (washing and finishing) in a
laboratory setting, this International Standard provides an approach using defined intermediate scale equipment and
exacting test procedures which may be used for the evaluation of workwear intended to be laundered industrially.
1.4 Testing of the workwear in the actual industrial laundering equipment and processes intended to be used is
advisable when finally determining product and process compatibility.
