Foreword

This standard is modified using the ISO 7769.:2006 "Test Method for Evaluating the Appearance of Polished Woven Fabrics" (English version).

The main differences between this standard and ISO 7769.:2006 are as follows.

- the word "international standard" is changed to "this standard";

- to remove the preamble of international standards;

--- normative reference documents in the international standard replaced by national standards;

--- delete footnote 1) on the pleated appearance of three-dimensional standard model of the purchase information.

This standard replaces GB/T 13770-1992 "Evaluation of the appearance of textured durable press products after washing and drying of household law".

This standard and GB/T 13770-1992 compared to the main changes are as follows.

--- Standard name changed to "Test method for the appearance of the fabric after it has been evaluated" the scope of the increase in the type of washing machine requirements;

--- normative reference documents to add GB/T .19981, delete GB/T 6151;

--- delete the terms;

- the principle of increasing the use of prescribed procedures;

--- remove the provisions of the plywood size and sample holder;

--- use "pleated appearance of three-dimensional standard model" instead of "AATCC plastic pleated three-dimensional standard or AATCC pleated standard sample";

--- the humidity of the sample from the "humidity 2h" to "humidity at least 4h, up to 24h";

- the program to increase the rating of the environmental requirements, the rating will be placed on the sample side of the three-dimensional standard model or standard sample modified to two Side (Figure 1 related parts modified);

--- Table 1 to increase 1.5, 2.5, 3.5 and 4.5 four grades;

--- the test report to increase the details of the sample, remove the rating criteria selection;

--- Add Appendix A "Precision and Bias".

Appendix A to this standard is an informative appendix.

1 Scope

This standard specifies a test method for assessing the retention of presses after one or several washings. By fabric characteristics the determined mosaic pleats are not included.

This standard is mainly applicable to GB/T 8629 provisions of the B-type home washing machine washing procedures, but also for A-type washing machine.
