Textiles - Industrial washing and finishing procedures for testing of work wear (ISO 15797:2017)

This document specifies test procedures and equipment which can be used in the evaluation of
workwear (including, where appropriate, for some PPE garments) intended to be industrially
laundered. They serve as a basis for testing relevant properties such as dimensional stability, colour
characteristics, creasing, seam puckering, pilling and visual aspects in general.
This document does not provide instructions and specifications for the procedures and equipment to
be used by industrial launderers.
As it is often not practical to reproduce industrial laundry processes (washing and drying/finishing) in
a laboratory setting, this document provides an approach using defined intermediate scale equipment
and exacting test procedures which can be used for the evaluation of workwear intended to be
laundered industrially.
As this document reflects a simulation of real-life industrial laundry conditions, in some cases, 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.
It is not necessary to test using all eight washing procedures nor both drying procedures. A selection is
made of the washing and drying procedure(s) that are best suited to the characteristics of the fabric or
fabric composition and the intended use.

Textilien - Industrielle Wasch- und Finishverfahren zur Prüfung von Arbeitskleidung (ISO 15797:2017)

Dieses Dokument legt die Prüfverfahren und Geräte fest, die zur Beurteilung von für das industrielle Waschen vorgesehener Arbeitskleidung (einschließlich, sofern angemessen, für einige PSA-Kleidungsstücke) verwendet werden können. Sie dienen als eine Grundlage zur Prüfung entsprechender Eigenschaften, wie Formbeständigkeit, Farbeechtheit, Knitterbildung, fehlerhafter Nahtkräuselung, Pillbildung und der allgemeinen optischen Aspekte.
Dieses Dokument enthält keine Anweisungen und Festlegungen bezüglich Verfahren und Maschinen für die industrielle Wäsche.
Da es in der Praxis oft nicht möglich ist, Industriewaschverfahren (Waschen und Finishen) in einem Laboraufbau wiederzugeben, liefert dieses Dokument 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.
Da dieses Dokument tatsächliche Bedingungen in einer Industriewascheinrichtung simuliert, wird empfohlen, die Beurteilung der Wascheigenschaften von Arbeitskleidung in manchen Fällen mit den zum Einsatz vorgesehenen Industriewaschmaschinen und -verfahren durchzuführen, wenn die Vereinbarkeit von Produkt und Waschverfahren abschließend zu beurteilen ist.
Ein Prüfen anhand aller acht Wasch- oder Trockenverfahren ist nicht erforderlich. Es werden Wasch- und Trockenverfahren ausgewählt, die am geeignetsten für die Eigenschaften des Gewebes bzw. der Gewebezusammensetzung und den vorgesehenen Verwendungszweck sind.

Textiles - Méthodes de blanchissage et de finition industriels pour les essais des vêtements de travail (ISO 15797:2017)

L'ISO 15797:2017 spécifie des modes opératoires et l'équipement qui peuvent être utilisés lors de l'évaluation des vêtements de travail (y compris de certains vêtements EPI, lorsque c'est pertinent) devant faire l'objet d'un blanchissage industriel. Il sert de base pour soumettre à essai des propriétés pertinentes telles que la stabilité dimensionnelle, le comportement des coloris, le froissement, la formation de faux plis, le boulochage et l'aspect visuel en général.
L'ISO 15797:2017 ne fournit ni instructions ni spécifications relatives aux modes opératoires et à l'équipement que les blanchisseurs doivent utiliser.
Puisqu'il n'est pratiquement pas possible de reproduire en montage de laboratoire les cycles de blanchisserie industrielle (lavage et séchage/finition), le présent document fournit une approche faisant appel à un équipement de capacité intermédiaire définie et à des modes opératoires d'essai rigoureux qui peuvent être utilisés pour l'évaluation des vêtements de travail destinés à faire l'objet d'un blanchissage industriel.
L'ISO 15797:2017 étant le résultat d'une simulation des conditions réelles de blanchissage industriel, il est recommandé, lors de la détermination finale de la compatibilité entre le produit et le cycle, de soumettre à l'essai les vêtements de travail dans les machines de blanchissage industriel existantes, selon le mode opératoire ciblé.
Il n'est pas nécessaire d'utiliser les huit options de nettoyage ou les 2 modes opératoires de séchage lors des essais. Il est procédé à une sélection du ou des modes opératoires de lavage et séchage les mieux adaptés aux caractéristiques de l'étoffe ou à la composition de celle-ci et à l'utilisation prévue.

Tekstilije - Postopki industrijskega pranja in plemenitenja za preskušanje delovnih oblačil (ISO 15797:2017)

Ta dokument določa preskusne postopke in opremo, ki jo je mogoče uporabljati pri vrednotenju delovnih oblek (po potrebi vključno z nekaterimi osebnimi zaščitnimi oblačili (PPE)), namenjenih za industrijsko pranje. Uporabljajo se kot podlaga za preskušanje ustreznih lastnosti, kot so dimenzijska odpornost, barvne značilnosti, mečkanje, gubanje šivov, piling in splošni videz.
Ta dokument ne podaja navodil in specifikacij za postopke in opremo, ki naj jo uporabljajo ponudniki industrijskega pranja.
Ker je poustvarjanje postopkov industrijskega čiščenja (pranje in sušenje/naknadna obdelava) v laboratorijskem okolju nepraktično, ta dokument podaja pristop, ki uporablja določeno opremo srednje velikosti in stroge preskusne postopke, ki se lahko uporabljajo za vrednotenje delovnih oblek, ki so namenjene za industrijsko pranje.
Ker ta dokument odraža simulacijo resničnih pogojev za industrijsko pranje, se pri dokončnem ugotavljanju združljivosti izdelkov in postopkov v nekaterih primerih za preskušanje delovnih oblek priporoča uporaba dejanske opreme in postopkov za industrijsko pranje.
Pri preskušanju ni nujno uporabiti vseh osem pralnih postopkov ali obeh sušilnih postopkov. Opravi se izbor pralnih in sušilnih postopkov, ki so najustreznejši glede na značilnosti tkanine ali sestavo tkanine in predvideno uporabo.

Introduction
This document enables manufacturers of textiles to test their fabrics and garments for resistance to
exacting washing and drying processes used in industrial laundries for care and maintenance purposes.
It is not practical to carry out rigorous testing in an industrial laundry environment and this document,
using intermediate stage equipment, allows testing to be done in a more exacting laboratory setting
under standardized conditions.
This document is a test method and is not intended as instructions or recommendations on how to
wash and dry in an industrial laundry. Nor does it provide specifications on equipment to be used by
industrial launderers.
A laundering cycle consists of a washing and a drying/finishing procedure.
