Xtester-ISO 2759 and ISO 2758 lab bursting strength testing machine for paper and cardboard
| Burst tester is the basic instrument for testing the anti-bursting degree of paper or cardboard, using Mullen test methods. |
Application
| Used to determine a variety of paper and not more than 2000kpa monolayer of thin cardboard, or a variety of single and multi-layer cardboard and corrugated cardboard can also be used to detect silk cotton and other non-paper products. |
Standards
| ISO2759, ISO 2758. |
Principle
| It adopts signal transmitting press. When the specimen is burst, the tester stores the maximum of bursting strength automatically. The sample placed on the membrane, with sample holder clamping and hydraulic pressure evenly, sample free raised together with the membrane, until the sample burst, the maximum hydraulic pressure strength is the burst value of the sample. |
Features
| Micro-computer control, use hydraulic oil as the driving force to break the specimen. When the specimen is broken, it stores the maximum and reset automatically. LCD displays, the unit of kgf/cm2, psi and kPa in option. It adopts signal transmitting press 5. Built-in printer, high speed print out the test results. 6. ISO 2759 and ISO 2758. 7. Show real-time curve |
