Wood Standard North China Science and Technology Co., Ltd. This standard mainly includes the following aspects: avoidance of the material, the material ... 3. Sample preparation
3.1 The test sample is 25m long and 25m wide. Two test samples should be drawn and their actual width should be measured at least twice/each, and the average value should be taken. Www.bzxZ.net
3.2 According to the resistance law, the standard sample resistance should be 1 times the test sample resistance. 4 Determination method
4.1 Estimation of resistance value
According to the law, the resistance of the test sample is calculated (for example, the thickness of the pure pin box is 307mm, and the selected test sample resistance value is approximately,
4.2 Measurement Fixed width temperature electric
Put the test sample on the fixture, put it in phase, m, and take the proportional bridge as 10. Record the reading of the double kidney bridge (fine-tune it with the rear resistance value of the test sample) R and record the room temperature at that time. Measure each sample once and take its half-average R..
4.3 Calculate the standard sample resistance at 20℃
Where,
The resistance of the test sample at ", in ohms; standard resistance value, R=G.501R:
Proportional correction, R,=10 2,
The average value of the double-passion electric selection band, in ohms (Q) Width correction factor:
Delay correction factor, =+a(20-, where is the resistance temperature change coefficient: =heart 4. Standard sample resistance value 18XR11××
