PY-J603G butterfly specimen vertical compressive strength test fixture is used to test the vertical compressive strength of butterfly specimens of various types of corrugated cardboard (including single-layer, double-layer and triple-layer corrugated board). Fix the upper and lower ends of the butterfly sample so that it is vertical, and place it between the compression plates of the ring compressive Strength Tester to test the vertical compressive strength.
Executive standard: JIS Z 0403-2 corrugated fiberboard-Part2:determination of edgewise crush resistance
Note: This accessory is the test accessory of the ring compression/edge compression Strength Tester, and it needs to be used together to test the edge compression strength of the cardboard.
The test method is to fix the clamps on the upper and lower ends of the butterfly sample to make it vertical, and then place the entire piece between the compression plates of the ring compression testing machine to measure the vertical compressive strength. The purpose is to test the vertical compressive strength of butterfly specimens of various types of corrugated cardboard (including single-layer, double-layer and triple-layer corrugated board).
