This method specifies the method for determining the color resistance of various types of textiles to the action of steam pleating. The specimens are not tested in the pleated state, so this test is not used to evaluate the quality of the pleating process. This method provides three test methods with different degrees of severity, one or more of which can be used as required.

ISO Foreword
150 (International Organization for Standardization) is an international organization for the benefit of international standardization. The international standard is approved by the 1S technical committee. Each member and the non-official international organization that has established a technical committee is interested in the project. The member shall contact the relevant party and participate in the work. S) shall be involved in all matters related to the standardization of engineering technology. The International Electrotechnical Commission (IEC) shall take the lead in the standardization of engineering technology. The international draft adopted by the technical committee shall be circulated to the members for voting. In order to promote the development of international standards 1S11>PI>2 as an international standard, the second edition was prepared by TSO/TC8/5C:1 Technical Committee on Tests for Dyes and Fragrances of Textiles, and the first edition (15101-1:198) was accepted and replaced by the TSO/TC8/5C:1 Technical Committee on Tests for Dyes and Fragrances of Textiles. [50103] 13 "Parts" have been published, each part being indicated by a letter (\A Part). As of 1978-1995, each part is comprised of a series of "Chapters", each containing a corresponding part and indicated by a two-digit series, i.e. "A1\). These are now published as separate parts, the original "Part" letters remaining unchanged.) 1-G have been amended to include a blank section, G3

.1 This method specifies the method for determining the color resistance of various types of textiles to condensation. The specimens are not tested under the quasi-baked state, so the test cannot be used to evaluate the quality of the workmanship. 1.2 This method provides three test methods with different thermal conductivity. According to the needs, one or more of them can be used. Reference standards
The following standards contain clauses that are cited in this standard and are all included in this standard. When the standard is not available, the versions shown are all valid.

The tube is wrapped with six layers of bleached cotton cloth with a unit area mass of about 125 g/m2. The sample is wrapped on it. The outer layer can be wrapped with a white cotton cloth with a unit area mass of about 185 g/m2. Two low-profile steel bars with a diameter of 6 II are respectively fixed at both ends of the cloth. Then two single yellow steel bars are used to fix the two ends of a steel rod and can be lightly constructed. The steel rod is made of a medical cloth wrapped with a medical cloth (see Figure 1).

for) the steam box with central layer shall be designed to be able to determine the pressure during the test so that the water will not be full. The type is: h) or a suitable domestic pressure cooker, its narrow area should be large enough to avoid the test on the test spirit, the minimum dimensions should be 230mm diameter and 260mm high, must be equipped with an accurate pressure gauge. The sample holder (4.1) should be loosely wrapped with a layer of polymer film, and the stock exceeds the tube every 10)m without falling off the tube. Normal sealing. The sample holder is placed in a container with ten 1mm small holes in the center of the container. The depth of the container should be 10m2 (see Figure 2). The bottom cavity of the container should be slightly shaped to ensure that the condensed water is quickly discharged. The container is separated from the water by a height of 100 m. Note 1: The amount of water in the container is not specified. A depth of 30mm is appropriate. The pressure should be increased by exhausting for 2 minutes, 65 m.3 Lining fabric

Hold the wire under the account and send it. 4.3.1 A piece of red woven fabric that meets the requirements of G1140: 4-3.2 or (735%~75% 31110) single fiber fabric, each piece is 10mm×100m, made of the same fiber as the tested textile, and the effect is easy to determine. If it is a transfer product, use two different pieces of woven fabrics, mainly made according to the example of the sample,
4.4 If necessary, use a different one! Color composition such as polyolefins) 4.5 Use gray silk to evaluate color change. Use gray card to evaluate color activity. G: 5.1 If the sample is For fabrics, prepare samples by one of the following methods: a) Take a 40mm×n:n sample piece, and inoculate it with a 41mm×1CCmm single fiber pasting fabric (2.R.1) - piece to avoid a short edge:
b) Take a 40mm×100mm sample, and inoculate it with a 4mm×100mm single fiber pasting fabric (4.3.2) on one short side.
5.2 If the sample is a 40mm×100mm sample, take a piece of 40mm×100mm single fiber pasting fabric (4.3.2) with a short edge ... 6.1 Place the combined sample in the sample holder (see 4.1) as shown in 1. 6.2 Hold the combined sample together with the combined sample in a non-sandwich steam box or kettle (see 4.2). 6.3 Steam under one of the conditions listed in Table 1: The steaming time should be longer than that in R/T 8438—155B. Table 1 Steam heating conditions. Treatment time at specified temperature: · ua. The test method is for pure finished products, and the products are not allowed to be steamed.
6.4 When the steam heating is completed, release the effective pressure within 2 min. Take the high pressure combination test: mark all the chains except one negative chain, and dry them in air at a temperature not exceeding T=20 and a relative humidity of 655%±2 for 4h66. Determine the color change of the sample and the color of the attached part (4.5). 6. In order to test the formaldehyde released under steam conditioning conditions, the samples should be tested separately. Note 4: These two notes are all true. For some conditions, some of them may also produce relatively safe colors. The test report should include the following contents: b) Sample format: c) Sample changes: 1) If sheep fiber fabrics are used, the color staining effect of each fabric used shall be reported (if the color staining levels are different, only the relatively strong staining shall be reported) If multi-fiber fabrics are used, the type of fabrics used shall be placed and the color staining of each type of fabric shall be reported: test conditions: that is, mild, that is, see table
