Overview
Paper (plate) Tear Strength instrument is a special instrument for measuring paper Tear strength. Its main technical indicators and performance parameters comply with the relevant provisions of ISO1974 and GB455.1 standards. It is a test instrument required by industries and departments such as papermaking, scientific research and product mass supervision and inspection.
Features
1. Comply with ISO1974 and GB455.1 standards
2. Measurement range 10~ 1000mN, resolution 10mN
3. Indication Error measurement upper limit value 20%~ 80% range +/- 1%, outside the range +/- 0.5% FS
4. < 1% within the range of 20% to 80% of the upper limit value of the indication repeatability error measurement, and < 0.5% FS outside the range
5. It is composed of pendulum system, paper holding mechanism, paper cutting mechanism and indicating device
Principle
The instrument is designed according to the principle of the Alimendorf tearing instrument. Its Working Principle is: after the pendulum with a certain potential energy in the tearing position is released, the potential energy is converted into kinetic energy, and the sample is torn to do work. The force required to tear the sample is indicated on the dial by the pointer. This force is the tearing value of the sample, in mN.
Applications
Papermaking, scientific research, product mass supervision and inspection
Standards
ISO1974 "paper (board) - Determination of Tear Strength (Alimondoff Method) ", GB455.1 "paper (board) Tear Strength Determination Method"
Steps
The instrument should be placed on a solid and stable workbench in a clean air environment at room temperature of 20 +/- 10 ° C.
Notice
