ISO/TC 38/SC 2/WG 3 - Domestic washing and drying

1.1 This document specifies domestic washing and drying procedures for textile testing. The procedures are applicable to textile fabrics, garments or other textile articles which are subjected to appropriate combinations of domestic washing and drying procedures. This document also specifies the reference detergents and ballasts for the procedures. 1.2 Provision is made for a) 16 different washing procedures based on the use of the reference washing machine Type A: horizontal axis, front-loading type, b) 12 procedures based on the use of the reference washing machine Type B: vertical axis, top-loading agitator type, and c) 7 procedures based on the use of the reference washing machine Type C: vertical axis, top-loading pulsator type. 1.3 Each washing procedure represents a single domestic wash. 1.4 This document also specifies six drying procedures: line dry, line drip dry, flat dry, flat drip dry, flat press, and tumble dry. 1.5 A complete test consists of a washing and drying procedure. NOTE Use of different parameters (washing machine type, detergent type and type of tumble dryer) can affect test results for any test using this document.

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.

ISO 23231:2008 specifies a test method for an accelerated procedure for determination of the dimensional change of fabrics which will then be made into garments or other end-use articles that will be laundered in a variety of settings. The procedure uses an apparatus with programmable settings that simulate multiple domestic or industrial laundering actions as well as wet processing operations in fabric manufacturing. This method is less suitable for heavy, tightly woven fabrics, such as denim, and fabrics with water-repellent finish. This method and the apparatus are not to be used to develop care labels. While ISO 23231:2008 is intended to measure the same dimensional property as in ISO 5077, its application is as an accelerated test for use in a production environment.

1.1 This International Standard specifies domestic washing and drying procedures for textile testing. The procedures are applicable to textile fabrics, garments or other textile articles which are subjected to appropriate combinations of domestic washing and drying procedures. This International Standard also specifies the reference detergents and ballasts for the procedures. 1.2 Provision is made for a) 13 different washing procedures based on the use of the reference washing machine Type A: horizontal axis, front-loading type, b) 11 procedures based on the use of the reference washing machine Type B: vertical axis, top-loading agitator type, and c) 7 procedures based on the use of the reference washing machine Type C: vertical axis, top-loading pulsator type. 1.3 Each washing procedure represents a single domestic wash. 1.4 This International Standard also specifies six drying procedures: A — Line dry B — Drip line dry C — Flat dry D — Drip flat dry E — Flat press F — Tumble dry 1.5 A complete test consists of a washing and drying procedure. NOTE Use of different parameters (washing machine type, detergent type and type of tumble drier) may affect test results for any test using this International Standard. Therefore, parties using this standard are strongly encouraged to agree on the parameters to be used.

Describes domestic laundering procedures for repeated washing at selected wash temperatures prior to assessing flammability behaviour of textiles. The washing machines and procedures specified are based on ISO 6330.

Applicable to fabrics, garments or other textile articles when subjected to an appropriate combination of specified washing and drying procedures. In the case of textile articles or deformable materials it is necessary to exercise all possible caution in the interpretation of the results.
