The tester is used to determine the rupture strength and rupture index of paper. The tester can be configured to meet any ISO, GB, ASTM or other International specifications for paper, foils, paper boards and corrugated board etc. The main instruments are suitable for cardboard manufacturers, paper mills, scientific research institutions, etc.
Applications
Paper, Cardboard, Corrugated, Metal foil
Features
● Pneumatic sample clamping, adjustable clamping force.
● Pressure curve, data recording and data management.
● Equipped with aluminum foil for calibration, you can calibrate the instrument by yourself.
● Equipped with air filter/regulator.
● Equipped with protective cover.
● Color touch screen, simple and easy to use.
Test Principle
The sample is placed into the circular test area and the test is started. The pneumatic clamping device will firmly fix the sample. The hydraulic fluid is pumped in at a stable rate and the pressure is gradually increased at a specified speed to make the sample and the film convex freely. From the moment the specimen ruptures, the maximum value of the applied hydraulic pressure is the bursting strength value of the specimen.
Standards
Paper：GB 454, QB 1057, ISO 2758, TAPPI T 403, ASTM D774, JIS P 8112, BS 3137
Cardboard：GB 1539, GB 6545, ISO 2759, TAPPI T 810, TAPPI T 807
