The test is carried out within the normal deviation range of the standard environment specified in GB2918, and the adjustment time is 24h, and carry out the test under this condition. 5.2 Appearance and color
Take three sections of 1m long profiles as samples and inspect visually under natural light. 5.3 Curvature
Take three sections of 1m long profiles as samples, place the sides of the samples parallel to the surface of the platform, use a feeler gauge to measure the distance between the side of the sample and the platform, accurate to 0.2mm, take the maximum value of the distance between the same side and the platform as the curvature, and take the maximum curvature of the three samples as the result. 5.4 Length deviation
Take three products and measure with a measuring tool with an accuracy of 1mm. 5.5 Wall thickness
Take three sections of samples and measure them along the width direction at any angle. Measure the wall thickness at three points accurately to 0.02mm, and take the minimum value of the three samples as the result.
5.6 Physical and chemical properties
5.6.1 Dimensional change rate after heating
Perform according to Article 5.12 of GB8814, the heating temperature is 85±2℃, and the time is 0.5h. 5.6.2 State after heating
After the test in Article 5.6.1, visually test the sample under natural light. 5.6.3 Acetone resistance
Perform according to the relevant provisions of GB9646.
5.6.4 Drop hammer impact
Per GB/T14153 The A method is used, the weight of the falling hammer is 1kg, the radius of the hammer head is 30mm, and the height is 1m. 5.6.5 High and low temperature dimensional change rate
