This standard is equivalent to IS105-Cn5.19S. It is one of the five standards for colour fastness to washing test methods. This standard has made the following modifications to GE3921-83: 1. The format of the cover and the title page has been modified according to GB1.1-S3, and the references to the foreword have been added. 3 analysis and 13 references have been added. The recommendation of three external test instruments has been deleted: the fine detergent is listed in Appendix B. 2. The unit of length is mm. 3. Distilled water is changed to graded water. 1. The test group of the textile judgment group is changed from four inverses to continuous one short inverses. 5. The use of multi-fiber pasting and single-fiber pasting has been added. From the date of implementation, this international standard will replace GB3921-83. The standard is proposed by the China Textile General Association, and this standard is under the jurisdiction of the Standardization Research Institute of the China Textile General Association. This standard is drafted by the China Textile General Association Standardization Research Institute, the Shanghai Textile Science and Technology Research Institute, and the Shanghai Silk Technology Research Institute. The main drafters of this standard are Qi Sanmin, Xu Jieshou, Wen Bao, Li Ming and Hu Nenmin. This standard was first issued in 193. This standard is entrusted to the Institute of Standardization of China National Electrotechnical Commission for interpretation. GB/3921:5-1997 ISO Foreword ISO (International Organization for Standardization) is an international union of national standards organizations (15) members. The preparation of international standards is completed through ISO technical committees. Each member has the right to replace the committee if it is interested in the purpose of the technical committee. It is advisable to contact non-governmental international organizations and may also cooperate with them. [ISO] In all matters of electrotechnical standardization, it maintains close contact with the International Electrotechnical Commission [IEC]. Draft international standards adopted by the technical committee are submitted to the member organizations with more than 5 votes for publication as international standards. The international standard S0105-C05 was developed by the S0105/TC38 Technical Requirements for Textiles. This fourth edition revises the third edition and replaces the third edition (S0105-C05: 1987). 1) 105 has been published in 13 parts, each with a letter (e.g., "A" and "B"). The publication period is from 1978 to 1985. And the part is divided into a series of "blue", each with a letter ("4", these "are now published in separate volumes" but still have alphanumeric characters. IS) 10-A01 gives the full list. 1 Scope

This standard specifies the fifth test in a series of non-selective color fastness tests, which has been designated as a test method for studying the fastness of colored textiles to non-selective washing. This series of tests will cover a range of washing conditions from mild to severe. Note: This method is only intended to determine the effect of washing on the color rate of the final product, it does not change the overall washing operation results. Referenced Standards

The test sample is placed in a specified combination of adjacent fabrics, placed in a humid environment, and then machine-dried under specified time and temperature conditions, and then washed and dried. The negative color of the sample and the stain of the adjacent fabric are evaluated with a color test card. 4 Equipment and reagents
4.1 Suitable machine container (obtained resistance A) is made of a water-soluble plastic container with a rotating shaft. The plastic rotating disk is a 5cmL+50mL glass or stainless steel container, 75mm in diameter and 5mm in height. 125 mim ± 10mm from the shaft and the bottom of the container range is 45mm ± 10mm. The rotation speed of the shaft and the container is 41/in2/min. The water bath temperature is controlled by a thermostat. The test liquid is kept at the specified temperature of 95°C ± 2°C. 4.2 The copper beads of the corrosive candle are preferably about 6mm, 4.3 Soap, the water content does not exceed 6, and the wells must meet the following requirements (calculated in mass): free water <calculated in Na:CO>
