What factors are affected by qinsun cardboard edge pressure test -qinsun

Today, I will share with you the precautions of the cardboard side pressure test. Is the data of the cardboard side pressure testing accurately affected?

1. The influence of the parallelism of the pressure plate: the upper and lower pressure plate is uneven. During the test, only some peak test results can be tested, and the average value can be measured. Data are inaccurate.

2. Impact of test dimensions: side pressure test size: paper sample should be 25*100mm, bars are parallel. The parallelism of paper -like is determined by the flat pressure sample knife.

3. Test speed of the side pressure tester: Standard reference speed: 12.5mm/min, the test results obtained when the speed is different, because the faster the speed, the greater the reaction force. The test results will be deviated when the speed of rising or falling is not performed in a standard state.
