1ISO Foreword
ISO (International Organization for Standardization) is an international federation of national standards organizations ([S] members). The preparation of international standards is proposed by ISC technical committees. Each member has the right to participate in the committee on which a technical committee has been established if it has an interest in a subject. International organizations, whether foreign or non-foreign, may also participate in the work by contacting ISO. ISO maintains close contact with the International Electrotechnical Commission (IEC) in all matters relating to electrotechnical standardization. Draft international standards adopted by the technical committee are circulated to the members with a vote of more than 75% before being published as international standards. Standards TS05-D and 150/TC38/SC1 were formulated by the Technical Requirements for Colored Anti-Dyes and Dyes Testing Committee of the New Textile Association.
This fourth edition has been technically revised and replaced by the fourth edition (I50 105-B04:1U88). IS105 has been issued in 13 parts, each part is represented by a letter (A), ranging from 1% to 19 years. Each part contains a series of extracts, each of which is shorter than the corresponding part and is indicated by a two-digit number (i.e. "A0[\). These bands are published as separate documents. The original part "headings" remain unchanged. ISO105-A01 gives the complete list. 150105 Part A and B of this part are only informative appendices. 1 Yingyuan

The missing product sample, that is, eight continuous silk sheep, is carried out according to the regulations. The lamp test is only carried out within the wide requirement. At the same time, eight blue wool standards should be covered with questions to prevent water from fogging on the quality. After the sample is plated, it will be compared with some single-color wool standards to verify the color. If the determination of moisture sensitivity (see 4, 51 textile group products is used, the blue sheep without sleep is compared with the standard: T oil gray sample card. 2 standard village materials and test preparations

4.2.1.1: Light source: good noise level, the relevant product is 59K~65K. 4.2.1.2 Filter meter, the light source and the sample and the color standard can make the forbidden light less. The light source used should have a light selection rate of at least 33! mm-75m. If the light source is between 4?9m~300m, it should be 4.2.1. Heat filter: keep the light between the test grid and the blue wool standard, which can make the outside radiation attenuate and reduce the infrared radiation contained in the sub-light. It is necessary to use a protective film to make it To reduce the amount, so that the air can meet the requirements of the filter mother! 4.2.2 The radiation meter can be used to measure the radiation limit and light exposure, approved by the National Quality and Technical Supervision Bureau on November 26, 1998, and implemented on May 1, 1993. In GB/T430-1998, the illumination on the surface of the sample is a function of the light intensity and the test distance of the lamp room. The monitoring end of the radiation meter controls the average radiation intensity. The meter can effectively determine a radiation intensity (i.e., unit area radiation energy, see Appendix B) at a point on the sample rack. 4.2.3 Fluorescence: Materials that do not emit light and are waterproof, such as aluminum or aluminum-clad hard cards. If the sample is velvet fabric, the cross-measure should avoid pressuring the surface of the fabric.
4.2.4 The gray sample should be used as follows: G12.jm. 4.3 The temperature of the air in the chamber should be measured by a thermometer. The sensing part of the thermometer should be sufficiently protected to avoid direct exposure to the lamp. The temperature should not exceed 4 °C during the drying period. The temperature should not exceed 20 °C in the test chamber (see 8427-93 for the plate). The strength of the sample and the blue standard should not exceed the average strength of the gold standard. 2.3.1 The test + test method is detailed in the following system. Spraying time 1min; Drying duration: 29mia
The test + spraying water should be 3 times of water. In particular, metal potential should not be used in the manufacture of pipes, water tanks and sprinklers. The test is carried out to determine the humidity and light radiation properties of the product, and the total number of climatic cycles is 15.

6.2.2 Dry the sample and the blue wool standard according to the conditions described in 6.1. When the drying and drying parts of the sample (5.4) reach the color sample card level 3, take out one of the samples and cover the second third of the blue wool standard with another sample: 6.2.3 Continue to dry the sample and the original sample until the color sample reaches level 2. If the blue wool standard reaches level 4 before this, the drying can be stopped and the blue wool standard for the test is obtained. 6.2.4 Prepare the sample and the original sample and replace the equipment. 6.2.5 If the test product has wet light effect, it must be tested for a period of 16 hours before flat absorption. 6.2.6 According to 7, evaluate the weathering color half degree, 6.3 Method 2
6.3.1 When there are too many samples to be tested at the same time, the method [ may be used. The basic feature of this method is to control the two periods of earning and drying by checking the color of wool. It is allowed to use a blue single wool standard to test "batches of samples with different weathering color rates". Save the material of the blue wool standard:
6.3.2 Put the sample and the monitoring wool. Continue the test according to 6.1 until the color difference between the exposed and unexposed parts of the blue sheep reaches level 1 on the color sample card. Then take out one sample from each pair of samples, and then use another mask to add blue and wool standard twice,
6.3.3 Avoid drying, until the color difference between the exposed and unexposed parts of the blue sheep reaches level 4 on the color sample card, take out the other test pens and obtain the wool standard.
6. 3.4 According to the force method of 7, the weather resistance of the test is evaluated. 6.43
This test is applicable to check whether the vehicle radiation energy will be approved. The sample is allowed to be collected in a single order, or the whole wool is screened and exposed to the sun: the main method is to remove the specified radiation. Then take out the sample and evaluate the wrinkle according to the provisions of 7. E.5 Drying
Before the sample is attached for evaluation, the group needs to be quenched in air at no more than 60 degrees. 6.6 This combination Test
Cut the tested or tested samples into a size of at least 15 m3 and place them on both sides of the original fabric of the same size and shape as the sample. The sample with the shorter exposure time should be placed on the side. Evaluation of weather fastness
7.1 According to the color difference produced on the blue wool standard in the same exposure time, the color difference between the sample and the original sample is evaluated according to the color difference produced on the blue wool standard in the same exposure time. The evaluation grade is the blue wool standard number with a color difference close to the sample. If the color change of the test piece is between the two blue wool standards, an intermediate grade should be given, adding 5-6. 7.2 According to the color produced on the blue wool standard when exposed for a long time, the test piece and the bottom material standard should be evaluated. The number evaluated is the blue wool cup number closest to the color difference of the test piece. If the color change of the sample is between the two blue wool standards, an intermediate grade should be given, adding 3-4. 7.3 If the size of the test piece exposed is larger than the blue wool When evaluating the color change, use the gray plate with the gray color difference between the grade 1 and grade 2 materials (Teaching 5 7.4). If there is a sample that is sensitive to light and humidity, after the 161 climate test, use the color column to evaluate the difference between the sample and the original column. If the change is greater than 1:1, it should be judged as wet light. If it becomes 1-≤ or 5, it is judged as non-wet photosensitivity, 7.5 "safe color" not only includes the real color, but also includes the change of hue, saturation, density or any comprehensive change of these characteristics, the difference is in the safe cabinet, but the density changes, the test box can be written and written, the rating rate can be increased, the effect of the rating letter & show it;

Summary about color fastness to lightwwW.bzxz.Net
A1 Textiles are usually exposed to light for a short time during use. Light can cause the color of colored fabrics to change, usually darkening. The color fastness of the fabrics used in the textile industry is not very large, so there must be some method to determine their color fastness. In addition, the dyed fabric will also affect the color fastness of the fabric. This standard cannot possibly cover all relevant aspects (for example, new dye manufacturers, textile wholesalers and ordinary consumers), as they have not yet gained in-depth knowledge of the technology and it may be difficult for those who are not familiar with the standard to understand the relevant requirements. The following non-technical test instructions are for those who find it difficult to understand the technical details of this standard: Test method The test product is a set of blue fabrics dyed with different intensities and numbers. The wool color fastness standard is carried out at the same time and under the same conditions. If the color of the wool sample is similar to that of the whole wool color, its color will be rated as Grade 1 in the previous year. These light fastness standards should cover a very wide range. Some fabrics will obviously fade after being exposed to strong sunlight for 2-3 hours, while some fabrics may not change even after being exposed to the sun for 2-3 hours. In fact, these dyes are more likely to fade than those used by them. The cloth is also long-lasting, there are eight blue sheep standard two waves to choose from, the blue single wool is the best quality, the color sheep with standard 3 is the most durable, if the blue single wool standard 4 is used in a certain time, then under the same conditions, in order to produce the same color blue sheep standard 3 with only two times the time, the color standard 5 will need about an additional time, so it is necessary to ensure that the materials of different cloths are tested at the same time and the color sheep need to be compared before making a standard color. The same color, the most important thing for dyeing fabrics is that the understanding of what is "color" is very different. Therefore, it is necessary to make the sample color into two color processes that can contain multiple opinions. From the perspective of durability, it is more reliable to evaluate the fading degree. Here, it is said that the fading degree is determined by comparing the color difference samples under a set of standard "Eastern color samples" (gray F is equal to the color tent, gray sample card grade 1 is equal to the color difference). In this way, the color sample card can break the symptom, and the color matching rate can be determined by the standard. However, the medium and severe grades are used as the pursuit. In fact, some fabrics will recover quickly under the sun, but the time--it will no longer be long! Under normal use, the overall slight fading will occur less, but in the table, this change over time is very important, as shown in the example; the piece of fabric will be put in the liver,A paper label with a price on it is placed on the fabric. After a few days, the label can be carefully examined and the label can be identified. The effect of the label on the fabric is to reduce the color of the fabric. At the same time, it is found that the blue wool label 7 is light and will return to the original color. This is because the light effect of the fabric is also half a degree. This light color change is the main factor of the bag. It can only be felt when there is a clear boundary between the eye and the front. These products are also very important in the group. The color of this light color can be determined in brackets. For example, the evaluation of the fabric selection (2) shows that the rheology of the blue wool 2 is called the rheology of the blue wool 2. In addition, there is a high light resistance rate of 7 bags || tt || 5. There is also an unusual color change ratio. The light effect color change phenomenon should be examined. This effect is manifested in When the material is under strong pressure, it will change at a faster speed. After that, it will be almost completely restored to the original state. The degree of color change of light effect is determined by the special test specified in G1B431. The special characters are added to the table. The new (P2>2 index color change effect of the color sample card is naturally more sensitive to the color of the beautiful hand. A is the most popular. There are also many tests that have been conducted for a long time. The hue will change completely under light: for example, brown can change to purple, blue can turn to purple. Color. This purple coin can be said to be enough to include him. In the past, there was a note on this point. The method used in B/T812 to GB/T8130 is very clear: whether it is the lack of medical or the color change rate, it is evaluated by the door: any color change is also included in the calculation, such as, in the research and development of the two green cities, the two external standards are still monitoring the color of the sheep standard, 31
GET 3430—1998
But one of them becomes lighter first and then turns to inner color, while the other becomes blue-green first and finally turns to pure overflow color. The former should be rated as "5", while the other
should be rated as "5 relatively blue". In the standard, the method used in GB/8426 to GE843 is to express the changes in the sample during the exposure process as completely as possible without over-mixing: time R
(radiation as shown)
Additional instructions for radiometer
The device used in this method is equipped with a monitoring/control radiometer with a normal external spectrum between 300nm and 100nm, which can accumulate the radiation of the radiometer. When the radiometer is used as described, it should be regularly inspected and tested by the manufacturer: 35
