Carton machinery characteristics and value

1, range

This standard specifies the method of determining the breaking strength of corrugated paperboard by hydraulic pressure increasing method.

This standard applies to the corrugated board with the breaking resistance of 350 ~ 5500kPa.

2, reference standards

The provisions contained in the following standards constitute the provisions of this standard by reference in this standard. The editions shown in this standard are valid. All standards will be revised and the parties using this standard shall explore the possibility of using the latest version of the following standards.

GB 450 - 89 paper and board specimens taken

Standard atmospheres for sample handling and testing of pulp, paper and board GB 10739 - 89

3, test principle www.chinacartonmachine.com

The sample is placed over the adhesive film, clamped with a sample clamp, and uniformly applied pressure to free the specimen together with the film until the specimen is broken. The bursting strength of specimen is the maximum value of hydraulic pressure.

4, definition

This standard uses the following definitions.

Bursting strength Bursting strength

Under the experimental conditions, the maximum pressure of corrugated cardboard can be uniformly increased on the unit surface perpendicular to the specimen surface
