Thickness: (R) Light porous plate, 100mm on both sides of the plate, each measuring point (1C5mm): each measuring point at the intersection of 1C5mm on both sides of the plate and the center of the plate (two points): six points, with the standard card and the standard card, take the maximum difference between the measured value and the specified size as the inspection value. Negative bending: the board is straightened by taking the edge point of the GR lightweight porous board and measuring the bending part with a straight line of 3.5, and the maximum value is the measured value. Board surface flatness: use a ruler and a precision ruler of GC lightweight porous board.It is necessary to add the diagonal measurement screen of the strip board, a total of two places, and take the maximum effective value of the maximum space between the ruler and the board as the effective value of the environment measurement, and the error is correct to 1 Liu angle. The blade measuring ruler measures the length of the two negative lines, and the difference is the detection channel. According to the seam, use a small ruler to measure the width and the detection degree, and take the actual measured value and the current fixed length!
