3 Terms and Definitions

The following terms and definitions apply to this standard. 3.1 Compressive strength of paper, cardboard and corrugated board under specified test conditions. 3.2 Sample is placed between the fixed platen and the movable platen, the pressure at a constant speed, pressure sensor detects pressure to take maximum resistance to compression test Test instrument. Note. This standard specifies a different type of compression tester, the beam bending type compression tester. This type of compression tester to produce elastic plate Beams Health and strain, and the stress - determining the maximum resistance to stress-strain relationship. Beam bending type compression tester has now been eliminated in China. Principle 4 Compression Tester operates according to the principle of the load pressure sensor, and uses standard quality or other traceable calibration standards.

5 Instruments

5.1 compression tester Compression tester at a constant speed operation, according to the principle of work stress and strain, and has the following features. 5.1.1 upper platen and lower platen 5.1.1.1 on the compression tester settings, two clips, each platen size should be large enough to fully meet the requirements of the sample. And with It has sufficient rigidity to resist significant deformation caused by compressive force. 5.1.1.2 should be firmly fixed platen, a movable platen amount of lateral movement during the journey should not exceed 0.05mm. Two platen surface should Parallel to each other, each 100mm parallelism error should be less than 0.05mm. Platen surface flatness error should be within 0.05mm. ......
