LFY-217C Automatic Burst Strength Testing Instrument

Main purpose

For the performance measurement of expansion force and expansion degree when various textiles, non-woven fabrics, leather, medical materials, etc. are subjected to forces in all directions simultaneously (using the elastic diaphragm method). 
Technical Specifications

1. Test area: 50cm²  7.3cm² 
2. Measurement range: 0 - 2 MPa. When the burst pressure exceeds 20% of the full scale, the accuracy is ±2% of the full scale. When the burst height is less than 70mm, the accuracy is ±0.02mm. 
3. Minimum graduation value: 0.002 MPa 
4. Pressurization rate: 100 - 500 cm2/min  Accuracy: 10% 
5. Maximum burst time: (99.9 ± 0.1) seconds 
6. Maximum expansion degree: (70 ± 0.02) mm 
7. The diaphragm should meet the following requirements: its thickness should be less than 2mm; 
8. Output forms: Printed output, Display output (including computers and printers) 
9. The clamping device should provide reliable sample clamping to ensure that there is no damage, deformation or slippage of the sample during the experiment. 
10. Power Supply: AC 220V 50Hz
