2.4.8.4 or, if the format is less than 129mm×184mm (32 open), measure 1 point in each of the four corners of the same sample; if the format is larger than 12mm×184mm (32 open), add 5 points on the same sample. 2.4.4 Test results
2.4.4.1 The color change difference of each test sample is calculated according to the following formula (-)
Wu, D: —The number of times the color density is measured for the first time,
The average color density between changes,
2.4.4.2 The color difference is the color difference of the product. .6 Color difference
2.6.1 Instrument: Use a spherical colorimeter, the color measurement disk of the object is not sent. The standard of the Chinese and English regulations is 3. The color must be regarded as 10, and the practical CE64 car supplement standard is from the world. 2.5, 2 volume! The four holes with a diameter of 25mm are used. If the number of holes is small, the width of the holes should not be less than 2mm.
2..a Test step: First measure the multiple ** of C1E**b* based on the color, and then test the color difference between the same color and H.
2.6 Point light selectivity
2.6.1 Instrument
2..1.1 The gloss meter should include a core and a mirror, which can condense parallel light into a beam of light and project it onto the surface to be measured. The optical system also includes the photoelectric model of the receiver with the lens field of view and the book with the information collection, the actual road diagram 1 is filled with
and the color film
and the color light is locked
and the information card ... 2.2 Instrument calibration 2.1 Working standard gloss sample plate The gloss meter must be equipped with standard plate, secondary standard plate and block as standard plate. The sample plate must be calibrated regularly and its working point must be stable. 2.6 At the beginning of each test phase and in the middle of the test, the gloss meter should be calibrated to ensure the instrument's response. When calibrating, first adjust the receiver to the local point, then adjust the light of the secondary standard plate so that it can correctly display the light and high degree, and then adjust the working standard to the lower standard light. The reading shall not differ from the standard value by more than 1 18 degrees.
2.6.3 Test procedure
2.8.1 The test piece must be smooth and wrinkle-free
GBTTOT87
2.8.82 The surface of the test piece must be reversed and tested at different points within 100 cm. The glossiness of each test piece must be equal but greater than that of a single test point. 2.8.3.3 The glossiness of each test piece must be equal but greater than that of a single test point. 2.6.4 Test results: The glossiness of the test piece after the test is the average glossiness of the test piece. 2.1 Layer bonding
