Adoption of GB 450-89 Paper and Paperboard Samples

Standard atmosphere for sample treatment and test of pulp, paper and paperboard GB 10739-89

3. Test Principle

The sample is placed on the film, clamped by the sample, and then applied uniformly to make the sample and the film protrude freely together until the specimen ruptures. The fracture resistance of the specimen is the maximum value of the applied hydraulic pressure.

4, definition

This standard adopts the following definitions.

Bursting strength 

Under the test conditions, the maximum pressure that the corrugated board can bear on the unit area is uniformly increased perpendicular to the surface of the sample.
