GB/T 8433-1998 Textiles - Tests for colour fastness - Colour fastness to chlorinated water (swimming pool water)

This standard specifies the method for determining the color fastness of various types of textiles to the action of available chlorine at the concentration used for disinfected swimming pool water. This standard specifies three different test conditions. Available chlorine concentrations of 50mg/L and 100mg/L are used for swimwear, and available chlorine concentrations of 20mg/L are used for accessories such as bathrobes and towels.

This standard is based on I50105-F.03:1SS4 Spinning color test E33: secondary oxidation water (alcohol coating water), and revised GB/8433-1987. The revised document is equivalent to 1S0105E05: 1194. This standard modifies and adds the following contents to CB/T8433-1987: 1. Based on GB/T8433-1987, 1995.1.12, the cover, title and writing format are modified, and the preface and LSO are added.
2. The text is modified to make it consistent with the ISU standard: 3. According to 1S103, Chapter 2 and Chapter 3 are swapped. 4. Chapter 2 introduces the standard.
5. Test water is renamed as Grade 3 water.
6. The unit of length is changed to mm.
7. Cancel the appendix and replace the content 4.3. The code for the amount of sodium thiosulfate \X\ is \". 8. Add the content of the test report.
This standard replaces G/T842-1937 from the implementation date. This standard is under the jurisdiction of the Basic Standards Branch of the Technical Committee for Textile Standardization. This standard is jointly drafted by the Standard Research Institute of the China Textile Federation and the Technical Supervision Bureau of the Textile Industry of Erhai City. The drafters of this standard are Tong Jin, Lu Wenbao, Qi Lingmin, and Xu Jieshou. This standard was first issued in 19R7. 45

ISO (International Organization for Standardization) is an international alliance of national standards organizations (with more than 50 members). The preparation of international standards also involves the launch of technical committees. Each member has the right to participate in the committees, both official and unofficial international organizations, and has obtained joint projects with the IEC and participated in the work. ISO cooperates with the International Electrotechnical Commission (IEC) in all matters related to the standardization of electrical technical standards. C) A draft international standard submitted by a technical committee can be circulated among members for submission. When more than 75% of the members agree, it will be published as an international standard. The international standard 1S10.E03 was prepared by the new technical committee IS0/TC.3S/SC1 for the testing of textile products and dyestuffs. The first edition was technically revised and replaced by the second edition (1$0105-E03:1S87). TS0n issued 13 "parts" five months ago, each part is represented by a letter (such as Part A), editions from 1978 to 1985, each part consists of ten dates. The references are listed in the corresponding part and are indicated by two-digit serial numbers (i.e., A0). These are published in separate documents, the original "part" headers remain unchanged, and the full list is given in TS) 5-A1. 4

This standard specifies the effective test method and method of liquid used for disinfection of service textiles during color removal. This standard specifies three different test methods, effective resistance concentration g/1g/1 for reading clothes, effective oxygen concentration g/1 for nursing clothes, towels, etc.
2 Reference standards
The following standards contain provisions that, through reference in this standard, may constitute the provisions of this standard. This standard is published and the versions shown are valid: All standards may be revised. All parties using this standard should discuss the possibility of using the following standard development and newer versions. 25-[Color sample for evaluating color change (51C5-A02s) GB/61107 Current product accuracy test (e[30105-A01: 9943 Principle
The fabric sample is treated with a certain concentration of sensitive material to verify the dry operation. The color of the sample is evaluated by the color non-card. 4 Equipment and reagents
