Bursting strength tester
Application field: Burst strength refers to the maximum uniform increase in pressure that paper or cardboard can withstand per unit area perpendicular
Product details
1、 Product Introduction:
The bursting strength tester is designed according to the internationally recognized Mullen method and is a specialized instrument for testing the bursting strength performance of various types of paper. Its performance parameters and technical indicators comply with standards such as ISO2758 "Paper - Determination of bursting strength" and GB454 "Determination of bursting strength of paper". The basic principle is to be able to clamp the sample with external force and break it with oil pressure. Depending on the clamping method, it can be divided into pneumatic bursting strength tester and manual bursting strength tester. Relatively speaking, the pneumatic rupture tester should be widely available in the market, mainly reflected in the convenience of sample testing and the accuracy of quantity testing. Compliant with relevant standards and regulations, using pneumatic clamping samples and LCD display, suitable for measuring the burst resistance of cardboard, corrugated cardboard, and other sheet materials.
2、 Instrument adopts standard:
ISO 2759： Method for determining the bursting resistance of cardboard;
GB/T 1539： Method for determining the bursting resistance of cardboard;
QB/T 1057： Paper and cardboard durability tester.
