CCSFH690 Measurement method of the average thickness of the steel plate:

a) The average thickness of the steel plate can be measured by automatic or manual methods;

b) The thickness measurement position of the steel plate: when the automatic method is used to measure, the distance between the measuring point and the side and the end of the plate should be between 10 mm ~

300 mm; When using manual measurement, the distance between the measuring point and the side and the end of the plate should be 10 mm~100 mm;c) as shown in Figure 1, at least two lines are selected for measurement, and at least 3 measuring points are selected for each line (when the measurement points of each line are more than 3 points

, the number of measuring points of each line should be equal, and the position corresponds): and calculate the average thickness of the steel plate according to the average value.
