The previous editions of the standard replaced by this standard are as follows: — GB/T 8629-1988, GB/T 8629-2001. Textiles — Domestic Washing and Drying Procedures for Textile Testing 1 Scope 1.1 This 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 standard also specifies the reference detergents and ballasts for the procedures. 1.2 This standard specifies the following washing procedures: 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; 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 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 Note: When decided through consultation between all parties concerned, oven drying procedure may be used, see also Annex Q. 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 standard. Therefore, parties using this standard are strongly encouraged to agree on the parameters to be used. 2 Normative References The following referenced documents are indispensable for the application of this document.
