width B is not less than 500mm of the plate, first cut off 50mm of the left end, and then take the same sample at the same position within the range of 0mm on both sides, and the center distance of the column piece in the direction of the plate width is not less than 1., and the corresponding edge distance in the length direction of the plate is not less than 20mm.
The center distance of the sample in the width direction of the standard material, mm; a-
One plate width, mm
For the board with a width between 300-500mm, first remove 50mm from the end, and then use the same sample pieces as shown in 2 within the range of 30mm from both sides. The center distance of the sample in the width direction of the standard material should not be less than, and the adjacent edge distance in the length direction of the standard material should not be less than 30mm:
The center distance of the sample in the upward direction of the plate is mn: 5
One material width, mm,

For plates with a crown length B less than 300mm, cut 50mm at the end and then take a piece from the inner length of the plate with a height of 20mm on both sides.
3 Sampling of molded plate
Molded plates are taken from the packaging box. The plates taken out of the box are first cut off 20mm on each side. After burning, they are divided into two parts using the quartering method. One part is used for sample preparation and the other is reserved.
