GB/T 8433-2013Textiles -- Tests for colour fastness -- Colour fastness to chlorinated water (swimming-pool water) (English PDF)

Foreword

This Standard was drafted as per the rules specified in GB/T 1.1-2009.

This Standard replaced GB/T 8433-1998 Textiles - Tests for Colour Fastness - Colour

Fastness to Chlorinated Water (Swimming-Pool Water); compared with GB/T 8433-

1998, the major changes are as follows.

--- In Chapter 2 Normative References, add GB/T 6682 and FZ/T 01024; delete GB/T

6151-1997;

--- Divide the original Chapter 4 into two chapters, i.e. Chapter 4 Apparatus and

Chapter 5 Reagents;

--- In Chapter 4 Apparatus, specify the containers for the test device, which is required

to be glass container rather than stainless-steel container;

--- In Chapter 4 Apparatus, add the spectrophotometer (4.4) and analytical balance

(4.5) to evaluate the color changes of the specimen;

--- Change Chapter 6 specimen dimension into (40+/-2)mmx(100+/-2)mm; the parallel

length into (100+/-2)mm; and diameter into (5+/-2)mm;

--- In 7.3 of Chapter 7 Operating Procedures, add the optional method for color change

of the specimen evaluated by the instrument;

--- Add Clause e) to Chapter 8 Test Report; add instrument rating result and indicate

the rating method to Clause c).

This Standard adopts the redrafting method to modify and use ISO 105-E03.2010

Textiles - Test for Colour Fastness - Part E03. Colour Fastness to Chlorinated Water

(Swimming-Pool Water) (English Edition); The major differences between this

Standard and ISO 105-E03.2010 are as follows.

--- Delete the foreword of the international standard;

--- In the Normative References, the international standards were replaced by

corresponding national standards and industry standards; delete the quotation of ISO

105-A01;

--- Add the rating method to Clause e) in Chapter 8 Test Report.

This Standard was proposed by China National Textile and Apparel Council.

This Standard shall be under the jurisdiction of Basic Branch of National

Technical Committee for Standardization of Textile (SAC/TC 209/SC 1).

Textiles - Test for Colour Fastness - Colour Fastness

to Chlorinated Water (Swimming-Pool Water)

1 Scope

This Standard specifies the method for determining the available chlorine action of

various colors of textiles against the concentration used by the disinfecting swimming-

pool water.

This Standard specifies three different test conditions. The available chlorine with

concentration 50mg/L and 100mg/L is used for swimsuits; while the available chlorine

with concentration 20mg/L is used for bathrobes, towels, and etc.

3 Principles

Select one of three specified test conditions, use the chlorine-containing dilute solution

with given concentration to treat the textile specimen, then dry it. Use gray scale or

spectrophotometer to assess the color change of the specimen.
