Overview
The YN-SLY16 microcomputer Tear Strength tester is a YINUO brand professional test equipment for the measurement of the force required to tear pre-cut paper. The instrument uses Optical inspection encoder technology to convert the tear angle position of the pendulum into tear units. It is suitable for the measurement of Tear Strength of various types of paper, as well as the detection of anti-Tear strength of sheet composites such as Cardboard, Spinning & weaving products, leather, film, etc. It is widely used in paper mills, scientific research institutions and Quality control departments.
Features
1. Optical inspection encoder for Accurate Measurement of Angles Position
2. Measurement range of 50~ 16000mN
3.3.2 inch LCD display, modular integrated thermal function
4. Suitable for a variety of material testing, including paper, Cardboard, Spinning & weaving, leather and film
5. Compact structure, weight about 30kg, easy to use in laboratory
Principle
The instrument stores potential energy by lifting the pendulum to a certain height. When the pendulum is free to pendulum, it uses its own energy to tear the sample (usually 4 layers) with a specified pre-cut by a fixed distance. By measuring the potential energy loss of the pendulum during the tearing process, the work done by tearing the sample is calculated, and the Tear strength of the material is determined.
Applications
Paper mills, research institutes, Quality control departments
Standards
GB/T 455、QB/T 1050、ISO 1974、JIS P8116、TAPPI T414
Steps
1. Prepare specimens of the specified size
2. Make pre-incisions on the specimen
3. Hold the specimen in a paper holder
4. Raise the pendulum to the initial angular position
5. Release the pendulum to free the hem to tear the specimen
6. Read and record the test results displayed by the instrument
Notice
• Ensure that the sample size meets the (63 +/- 0.5) mm * (50 +/- 2) mm specification requirements
• Pre-cut length should be accurate 20mm
• Maintain proper clamping force when clamping the specimen
• Regularly calibrate instruments to ensure Test accuracy
Maintain a stable test environment to avoid external interference
