This standard has the following meanings.
31 Secondary color measurement
Color measurement is the process of measuring the color of an object with a numerical value, and the average compensation of a single multi-point measurement is shown in a continuous test. 3.2 Color measurement can be performed by measuring the reflected (or transmitted) light of a sample in a range of 26m--780m, and the instrument (such as a colorimeter or optical colorimeter) can be used to measure the reflected (or transmitted) light of a sample in a range of 4m--26m. 3.3 Conditions of color measurement can be performed by using one of the following conditions/observation conditions:

Use the colorimeter to measure a piece of calibrated material. Note: In order to make the instrument meet the requirements of the company's specifications, the manufacturer of the instrument generally performs corrections. 3-10 standard rifatrNlarll
is used to: or to verify the effectiveness of any stable material in avoiding over-interpretation of the instrument standardization. For the purpose of wide inspection of inappropriate standards: Before separation of the color, compare the original measurement standards. 4 Principle
Use the reverse direction to measure the additional color of the material that is not bright or almost not bright but not translucent. The colorimeter can be used with a thick plate and calibration training instrument. The sample can contain chemical properties, which can be controlled and intentionally reflective. 2. Determination conclusion, the instrument should be selected according to the type of colorimeter, the type of colorimeter, the measurement area, the lighting method and the working conditions. The different types of receivers can not be fully used to obtain the data. 5. Equipment
5.1 Reflection colorimeter: It uses complex light (lighting) and the loss of transmission is different. Monochromatic light or only suitable for non-color testing, the reflection colorimeter can be roughly divided into two groups. 1 Harmonic colorimeter (-) is an instrument that uses transmission/colorimeter to measure the spectral reflectance factor under conventional conditions (for example, 1Cnm and 2Jnm). This number can be used to calculate the stimulus value (X, Y) of the given condition.Z》: Some spectral photometric instruments can be used to measure the color coordinates of the three stimuli, and can produce a chromaticity value under the conditions of illumination and observation [generally self/2 conditions]. The chromaticity rise cannot be measured because the spectral reflectance ratio of the above two types of instruments is determined by the geometric case specified in 3.3. When the sample is slightly placed at 1/0 (identification sphere), the light source is directed back to the sample at the light hole of the integrating sphere, and the sample is observed at a U\~·1C angle with the sample. This method is called the total reflected light of the sample. The observation angle can be greater than (\). This integrating sphere instrument position contains a mirror reflection and receiving technique, and can be measured using a method that includes or includes surface reflection. The central integrating sphere assumes that the lighting and observation conditions are similar to those mentioned above. The sample is irradiated at a temperature of 0\~1℃ in the test method. The reflection amplitude from the inner surface of the integrating sphere is measured. 130/7. Under any conditions, the first one points the sample with a degree of irradiation, and the second one observes the new sample. This method can be used with GD/T 6424.12001
Illuminate the observation sample at a 45\ angle in the whole circle. For most fabric samples, 5/absorption/45 is the best. 5.2 Calibrate the instrument with a color standard. The colorimetric values used for calibration can be stored in the instrument or in a soft book - only used when calibrating. 5.3 When a color standard is required, it can be zero reflected light. The method for calibration is suitable for 5.2. tt||61
a Receive customer samples and take photos, and select the best ones. If there are special samples, they can be sent out for adjustment. The factory will calibrate the instrument according to the provisions of .2, ensure the measurement and verification of the results according to the requirements of .4 (see also Appendix A), and place the test column on the instrument to determine the sample color to obtain the desired test results. Get the appropriate official reflectance value or colorimetric value (or colorimeter book three judgment values e! If necessary, please read the following? Listen to the color effect. 6.2 Calibration
In order to obtain an effective and accurate result, any color measurement unit must be calibrated before testing. Although the calibration method may vary due to different instrument models, the principle of calibration still exists. In short, the calibration of the instrument and the measurement should be based on the effective reflectance of the individual mouth silk table dream completely radiated diffuse body and the total number of instruments or computers are suitable for subsequent measurements. The calibration system. - This instrument also requires a black (complete sunlight device) and a complete board. These materials should be intact and kept clean. The table shows: 1. The instrument manufacturer's instructions for the instrument can make the currency analysis, the calibration frequency, and the influence of the internal system, including the model of the instrument, the severity of the instrument's operation, and the accuracy required. When used frequently, it can generally be 24 .
After the calibration procedure is completed, the effect of the calibration process is very important. If the set value exceeds the allowable error, the calibration is considered to be ineffective. The acceptance range of the inspection standard depends on the user's requirements. However, the acceptance range of 1~3 standards and .2 is representative.
All measurements performed by the colorimetric instrument involve sampling: only the observation of the instrument, the effective surface of the sample and the sample are placed on the light-proof hole of the instrument. Some items (clothing, city clothes, batches, etc.) are selected in the previous operation to obtain good representative samples.
Method: Thai original A word M method 1M and 3A method! 154 With appropriate rate, the specification of J1545 is as follows: 6.4 Test column preparation
The test specimen for determination is a test specimen with a uniform color and a straight, non-elastic shape. Such a test specimen does not exist in textiles. Therefore, when measuring textile materials, it is necessary to use technology and experience to eliminate or reduce any spectral errors that may affect the instrument's measurement. The following performance test methods are required when applying the following methods. ) The fluorescence of the specimen (from dyes or fluorescent brighteners) will affect the test results. The total effect of the instrument and the number of ultraviolet rays and the quality of the layer are detailed in the original collection method. The results are only between the instruments, for example: white or light-colored materials are buried under the judgment.
The content of mixed materials will affect the color and appearance of the fabric, the number of times it is conditioned, the number of times it is conditioned, the number of times it is conditioned, the changes in the design and the quality of the fabric must be determined in order to reach a stable quality state. The materials affected by the present invention are not cotton and rayon. The test specimens are stretched to the light transmittance of the receiver (the changes will make the test quality range larger and cannot be reproduced due to the high number of layers, the high resistance of the test agent, the change of the test quality will make the test quality range larger and cannot be reproduced due to the high resistance of the test agent. These materials are fiber, warp, mesh and lightweight fabrics. During the actual test, the light can be passed through the material to determine the quality of the fabric. For some fabrics, the light penetration through the material (or out of the device) will not be real and will not meet the requirements: this material is a lightweight fabric and silk fabric. The sensitivity of the sample to light (light-induced discoloration) (or heat-induced discoloration) will lead to unpredictable and irreversible changes in the sensitivity of the sample and the amplitude of the recorded light. The length of the test piece is very important in obtaining a representative measurement result during normal measurement. If the sample is too small, special techniques need to be used to obtain accurate color results. The surface structure of the sample (including velvet, material texture, gloss and glitter) will affect the initial color effect: when using an instrument with different structure to measure, due to the different geometric structure of the instrument, different results will be produced between different instruments: this includes: onions, wicks and yarns.
) The internal light distribution of the sample (incorrect) causes inaccurate and irreproducible results, which is related to the observation surface of the instrument, for example, cloth and leather.
