6 Samples
Send and take samples according to the provisions of Chapter 5 of GB/T5480.1-2314, and make sure that the samples are single-unit: 7 Test steps
7. Determination of weight
7..1 Verticality of end faces
Put the whole sample and the square on a hard platform, point the square on the upper (lower) side of the sample, and use a vernier caliper or a ruler to measure the value: see Figure 11. Read the accurate value.0]mr. Thickness shall be determined according to GB/T 482.320n1, Section 7.2. GE/T 5480,220Q4. 1. The verticality of the surface shall be expressed in 1.0 and 1.0 effective figures shall be given. The largest one shall be taken as the verticality factor of the single product.

7.1.2 Before the test piece is placed on the test platform, the edge of the angle ruler shall be aligned with the angle of the sample. The angle ruler shall be aligned with the angle of the sample. The value of the test piece shall be measured by a ruler or a ruler (see Figure 2). The reading shall be accurate. 1.11mm. The H value shall be measured with a tape measure. The value of the penetration shall be accurate. 1 mnl.
Repeat the above steps, measure the A value of the other sides of the plate and the value of the user's A value as a single product.

Figure 2 Two degrees of rigidity
.2 Flatness
Put the sample on the plate platform with its concave surface at a known position: the test block at both ends of the vertical position can be placed separately, and the rigid ruler is placed on the two blocks with two degrees of Y. The first depth mark! The ruler is the distance between the sample and the straight ruler, which is called the extension point of the sample. Figure 3 is appropriate to 0.:m. The length and width of the longitudinal position shall be determined in accordance with the provisions of GB-8U.3, Article 2.2.- Calculation and test results of the sample: 8.1 The verticality of the end surface shall be calculated according to () or () where: w-verticality of the end surface, % Figure 3 Determination of flatness The sample item is the height of the edge of the scale point, sample number, mm, and the maximum value of the measurement result of each sample is expressed. Keep two significant figures, 8.2 Please discard the two right angles (2) - calculation:
