1 Scope
This standard specifies the determination of dimensional change of textiles in washing and drying.
This standard is applicable to determine fabrics, garments and other textile articles.
Various factors shall be considered during explaining test results of textile articles or proteiform materials.
2 Normative References
The following standards contain provisions which, through reference in this text, constitute provisions of this standard. For dated reference, subsequent modification to, or revisions of, any of these publications do not apply. However, all parties coming to an agreement according to this standard are encouraged to study whether the latest edition of these documents is applicable.

3 Principle
The specimen shall be of conditioning and measured with dimension under specified standard atmosphere before washing and drying, and then again after specimen drying and the dimensional change ratio of specimen shall be calculated.
4 Equipments and Reagents
They shall be implemented according to the relevant specifications of GB/T 8628 and GB/T 8629.
