Overview
The LD-NP-01 Burst Strength Tester is an international general-purpose Mullen instrument of JINGHUAYIQI brand, which is widely used in Encasement materials. It is mainly used to measure various Cardboard and single-layer and multi-layer Corrugated Board, and can also be used for Burst Strength testing of non-paper materials such as silk and cotton cloth. The instrument adopts fully automatic operation, automatically detects, tests, returns oil pressure, calculates, stores data and prints after placing materials, and digitally displays and automatically processes test results.
Features
1. Fully automatic operation, automatic detection, testing, oil pressure return, calculation, storage and printing data
2. Digital LCD display, support unit conversion (kpa, psi, kgf/cm2)
3. High Accuracy measurement, Precision up to +/- 0.5%
4. The clamp ring is made of stainless steel SUS #304, and the diameter is accurate to φ 31.5 +/- 0.05mm.
5. Complete standard configuration, including rubber film, wrench, correction piece, silicone oil, optional air pump
Principle
The instrument senses the Burst Strength of the material through the pressure converter, adopts the hydraulic system with silicone oil as the medium, the oil feeding speed is controlled at 170 +/- 10mL/min, and the pressure is applied until the material breaks, and the result is automatically calculated and displayed. The sample clamping force exceeds 690kpa to ensure the test Stability.
Applications
Encasement materials, Cardboard, Single and Multi-layer Corrugated Board, Silk, Cotton and other non-paper materials
Standards
JIS-L1004、L1018、L1031、K6328、P8131、P8112、ASTM-D2210、TAPPI T403、ISO2759-2001、GB/T1539
Steps
1. Put the material into the instrument
2. The instrument automatically detects and starts the test
3. Automatic oil pressure return
4. Automatically calculate and store test data
5. Print test results and data processing
Notice
• Power supply voltage is 1 * AC220 +/- 10%, 50Hz
• Use designated silicone oil as hydraulic medium
• Regularly check the diameter and clamping force of the clamping ring
• Follow relevant safety standards
