has been moistened with water to rub each places back and forth for 3 times with appropriate force, the reciprocating distance of the rubbing is 200 mm ~ 300 mm. Observe whether the gauze is stained by the coated parts.
6.2.2 Other appearance
Under natural light or near natural light (such as 40 W fluorescent lamp) with an illuminance of 300 lx ~ 600 lx, the line of sight is 700 mm ~ 1000 mm, which is jointly tested by three people. Most of the same conclusions are used as test results.
6.3 Determination of main dimensions and dimensional deviation
Place the test piece on a panel or flat ground surface, use a steel tape measure or steel ruler with an accuracy of not more than 1 mm to make determination. The dimensional deviation is the difference between the identified value of the product dimensional deviation and the measured value.
6.4 Shape and position tolerance measurement
6.4.1 Determination of warpage
It shall use the warpage measuring instrument with an accuracy of not less than 0.1 mm. Select the panel with the most warpage, place the appliance on the diagonal of the panel to make measurement, wherein the maximum distance is used as the warpage measured value.
6.4.2 Determination of flatness
Use the flatness measuring instrument with an accuracy of not less than 0.01 mm. Select the three panels with the most unevenness, measure the distance between the length of 0 mm ~ 150 mm on the surface and the reference line, use the maximum distance as the measured value of the flatness.
6.4.3 Determination of the perpendicularity of the adjacent side
Use the steel ruler or tape measure with an accuracy of not less than 1 mm to measure the two diagonals and the length of the opposite side of the
rectangular panel or frame, the difference is the measured value of the perpendicularity of the adjacent side.
6.4.4 Determination of position margin
Use a position difference measuring instrument with an accuracy of not less than 0.1 mm. It shall select the part with the maximum distance between adjacent surfaces for determination, select any surface as the measurement reference surface, place the base surface of the appliance on the measurement reference plane for measurement (measure another one or more parts along It is determined in accordance with the provisions of 4.44 of GB/T 17657-2013, the number of test pieces is three, which should be obtained from the product. 22.214.171.124 Impact resistance determination
It is determined in accordance with the provisions of GB/T 4893.9-2013, the number of test pieces is one, which should be obtained from the product. 126.96.36.199 Determination of light fastness
