Textiles - Domestic laundering procedures for textile fabrics prior to flammability testing (ISO 12138:2017)

ISO 12138:2017 specifies methods for repeated domestic laundering at selected wash temperatures prior to assessing flammability behaviour of textile materials. The washing machines and procedures specified are based on those given in ISO 6330:2012, but specific requirements are provided for water hardness and volumes, detergent type and quantity, machine loading and degree of agitation.

Textilien - Nichtgewerbliche Waschverfahren für Textilien vor der Entflammbarkeitsprüfung (ISO 12138:2017)

Dieses Dokument legt Verfahren für wiederholtes nichtgewerbliches Waschen bei ausgewählten Waschtemperaturen zur Anwendung vor der Beurteilung des Entflammbarkeitsverhaltens von Textil-materialien fest. Die festgelegten Waschmaschinen und Waschverfahren beruhen auf ISO 6330:2012, jedoch mit spezifischen Anforderungen an Wasserhärte und -volumina, Waschmitteltyp und -menge, Beladung der Waschmaschine und den Grad des Reversierrhythmus.

Textiles - Méthodes de lavage domestique des étoffes en vue des essais d'inflammabilité (ISO 12138:2017)

ISO 12138:2017 spécifie des méthodes de lavages domestiques répétés à des températures de lavage sélectionnées avant d'évaluer les propriétés d'inflammabilité des matériaux textiles. Les machines à laver et les modes opératoires spécifiés s'appuient sur ceux indiqués dans l'ISO 6330:2012, mais des exigences particulières sont données pour la dureté et les volumes d'eau, le type et la quantité de détergent, ainsi que sur le chargement et le degré d'agitation de la machine.

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 on 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 the following

This document was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 2, Cleansing,

finishing and water resistance tests.

This second edition cancels and replaces the first edition (ISO 12138:1996), which has been technically

revised.
The main changes compared to the previous edition are as follows:

— The text was updated to use the washing machine technology currently available. Referenced herein,

ISO 6330:2012 incorporated significant changes to washing machines compared to its previous

editions. This second edition of ISO 12138 incorporates those updates, throughout.

— Additionally, this second edition incorporates a reference to ISO 139, which provides direction for

atmospheric conditioning prior to flammability testing.

Introduction

The methods specified in this document provide standardized domestic laundering procedures for

use prior to assessing the likely flammability behaviour of textile materials. The methods are based on

ISO 6330:2012 but incorporate several additional features which ensure that certain critical parameters

are more closely controlled. Alternative procedures for commercial laundering prior to assessing the

flammability of textile fabrics are given in ISO 10528.

Because of the wide variety of laundering methods used domestically, it is impossible to specify

a standard laundering procedure which will reproduce the effect of laundering under all possible

conditions. The methods specified, however, can be used to detect which materials are adversely affected

by domestic laundering under conditions which are appropriate for the material being laundered. Such

adverse effects are not restricted to textiles which have been treated with flame retardants.

The flammability of textile materials can be affected by a combination of different results:

— fibre content;
— effect of mechanical finishing/surface texture changes;
— shrinkage or growth of the material, causing a change in mass per unit area;
— abrasion of the material, causing a decrease in mass per unit area;
— removal of finishes;
— chemical modification of the fibre or finish;
— deposition of hard-water salts;
— including application of softeners in the rinse cycle;
— moisture content of the product under flammability evaluation.

The various factors in these test methods are controlled in order to standardize all these effects as far

as possible. The essential features specified in the methods are:
a) water hardness;

A medium water-hardness level is specified in order to ensure that any major effects caused by

deposition or chemical modification are detected. Different procedures for preparing this hard water

are given, depending on the hardness of the initial water supply.
b) degree of loading and composition of load;

These factors influence the mechanical action of the washing machine and the deposition results.

c) volumes of liquor used for washing and rinsing;

The liquor:fabric ratio affects the mechanical action and the deposition results. In addition, it is

essential to know the volumes of water being used in order to make any necessary adjustments to the

water hardness.
d) type and quantity of detergent;

The use of a standard nonphosphate detergent containing sodium percarbonate and a bleach activator

is recommended because of the increasing use of this type of detergent. The detergent used shall be

agreed between the interested parties. The detergent can affect the chemical modification of a material

or finish by its bleaching action, and also affects the deposition because of the sequestering effect of the

nonphosphate builders included in the formulation.

e) wash temperatures;

Four standard wash temperatures are specified so that the appropriate temperature for the material

being laundered can be selected.

NOTE The combination of hard water and high perborate detergent used in this document is not suitable for

laundering flame-retardant materials at temperatures above 60 °C.
f) degree of agitation;

The heating period can vary considerably depending on the inlet water temperature and the heating

capacity of the washing machine. Reduced agitation is used during filling and heating in order to avoid

variations in mechanical action. Normal agitation is specified for the 12-min washing period for washes

at 50 °C and 60 °C, but reduced agitation is used during the washing period for 30 °C and 40 °C washes.

g) rinsing procedure;

A standard rinsing procedure is specified, as rinsing can have considerable influence on the deposition

of hard-water salts. Fabric softeners added to the rinse are not used in this method.

h) washing machine.

The methods as presented allow the use of three different types of washing machine. As far as possible

the same laundering conditions have been specified for each type of machine. The degree of loading

is 60 g per litre of drum volume, and the detergent quantity is 20 g per kilogram of wash load. For

horizontal drum machines (Type A), the liquor:fabric ratio is 5,0:1,0 for washing and 9,0:1,0 for rinsing.

The mechanical action and the liquor:fabric ratio (20:1) used in the vertical drum machine (Types B

and C) are different from those used in the Type A machines. Experience indicates that testing with

this type of machine is equally effective in detecting finish removal, although mechanical effects and

deposition results may be different
