A1 and Type A2; the specifications of washing machines are adjusted to corresponding
annexes (see Clause 5; Clause 5 of Edition 2001);
— Table 3 and the requirements of dryer used with corresponding type of washing machine of
the original standard are deleted; dryers are classified into Type A1 (vented), Type A2
(condenser) and Type A3 (large vented); the specification parameters of dryers are modified,
and the parameters are adjusted to corresponding annexes (see 5.2; 5.2 of Edition 2001);
— Specification parameters and selection method of ballast are modified, and the parameters are
adjusted to corresponding annexes (see 5.6; 5.3 of Edition 2001);
— 5.7 "Oven" of the original standard is deleted (see 5.7 of Edition 2001);
— Clause 7 "Conditioning and Testing Atmosphere" is added (see Chapter 7);
— The provisions of wash load and ballast in Clauses 6 and 7 of the original standard are
adjusted to Clause 8 of this standard (see Clause 8; Clauses 6 and 7 of Edition 2001);
— Partial provisions of washing procedures of washing machine Type A (Table 5 of the original
standard) are modified; except simulated hand wash, the sequencing series number of “1A,
2A, 3A...” are revised as the code series number of the first digital, which represents wash
temperature, plus the first letter of agitation type (Normal, Mild and Gentle), for example,
original series number 5A is adjusted to 4N, and Table 5 of the original standard is adjusted
to Annex B (see Annex B; Table 5 of Edition 2001);
— Partial provisions of washing procedures of washing machine Type B (Table 6 of the original

standard so that the technical conditions in China are met; the adjustment situations
embodied a concentrated reflection in Chapter 2 "Normative References", and the specific
adjustments are as follows.
ISO 139 is replaced by GB/T 6529, which is modified in relation to the international
standard;
ISO 6059 is replaced by GB/T 7477 which is identical to the international standard.

Textiles - Domestic Washing and Drying Procedures for
Textile Testing
1 Scope
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.
For dated references, only the edition cited applies. For undated references, the latest edition
of the referenced document (including any amendments) applies.
3 Terms and Definitions
For the purpose of this document, the following terms and definitions apply.
prolonged drying operation where the load is dried until all remaining moisture in the load has
been removed
4 Principle
A specimen is washed in an automatic washing machine and dried according to specified
procedures.
5 Apparatus and Materials
For procedure for line drying, see 10.1.1; for drip line drying, see 10.1.2.
Use screen drying racks of approximately 16 mesh stainless steel or plastic for flat drying (see
10.1.3) or drip flat drying (see 10.1.4).
The nominal composition of 100% Polyester ballast is given in Annex H.
6 Reagents
The laboratory water-supply pressure at the inlet to the reference washing machine shall be higher
than 150 kPa.
The water temperature at the inlet to the reference washing machines shall be (20 ± 5)℃.
In tropical countries, the water temperature (20 ± 5)℃ should be regarded as a minimum
temperature. When the measurement is carried out with a water temperature that differs from these
limits, the supply temperature should be stated in the test report.
7 Conditioning and Testing Atmosphere
The atmospheres used for conditioning textile specimens shall be in accordance with GB/T 6529.
8 Wash Load
The number of specimens will be determined by the purpose for which the material is being
tested.
If dimensional stability is being determined, not more than half of the wash load shall consist of
test specimens.
9 Washing Procedure
After the washing procedure has been completed, remove the test specimen(s) carefully,
ensuring that they are neither stretched nor distorted, and dry according to one of the drying
procedures described in Clause 10.
