GB/T 5717-2013Textiles -- Tests for colour fastness -- Colour fastness to spotting: Water (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard replaces GB/T 5717-1997 "textile color fastness test water spot color fastness", compared with the GB/T 5717-1997 the main changes are as follows.

--- Delete the original standard ISO foreword;

--- Normative references removed GB/T 6151-1997, an increase of GB/T 6682 and FZ/T 01024;

--- Added optional instrument method of evaluation;

--- The original standard, Chapter 4 of this standard split Chapters 4 and 5, the subsequent chapters postponed;

--- Chapter 4, add a "spectral color measurement instrument (4.4)";

--- Chapter 6 increased the sample size and cut tolerance of ± 2mm, sample preparation method of yarn from the "truss ends" to "be made Thin ";

The 7.3 --- drying procedure, from "hanging in the air at room temperature to dry" to "dried at room temperature";

--- Chapter 8 test report adds d) requests.

This standard uses redrafted law revision using ISO 105-E07.2010 "Textiles Tests for color fastness Part E07. water spot color Fastness "(in English). This standard and ISO 105-E07.2010 main differences are as follows.

--- Deleted international standards in the preface;

--- Normative references to international standards is replaced by the corresponding national standards or industry standards, specific adjustments are as follows.

- equivalents adoption of international standards GB/T 250 instead of ISO 105-A02;

- Modify with international standards of GB/T 6682 instead of ISO 3696;

- non-equivalent to international standards FZ/T 01024 replaces ISO 105-A05.

The standard proposed by China Textile Industry Association.

The standard basis by the National Textile Standards Technical Committee of Standardization Technical Committee (SAC/TC209/SC1) centralized.

This standard was drafted. Textile Industry Standardization Institute, the Shanghai textile industry technical supervision, Shanghai and linen textile science and technology research Studies, Dali (China) Limited.

1 Scope

This standard specifies the test method for the determination of various types of textile water spot color fastness.
