ISO 2759 Microcomputer Ring Crush Strength Testing Machine
This precision testing machine is designed to evaluate the compression resistance of corrugated paper and kraft paper in the upright direction under specified conditions. The equipment can also perform flat crush strength tests, compression resistance tests, adhesive strength tests, and various other compression analyses.
Key Applications
The Ring Crush Strength Testing Instrument is used to measure anti-rupture strength for raw paper, corrugated cardboard, leather, cloth, and synthetic leather. It automatically records force values and maintains maximum fracture strength readings, with resolution improved 100 times compared to needle display types. This equipment is essential for quality control in manufacturing processes.
Compliance Standards
ISO 2759, GB/T 1539, QB/T 1057, ASTM D3786, GB/T 6564, GB/T 465
Industry Applications
Suitable for testing anti-breaking strength of packaging boxes across multiple industries including electronics, electrical appliances, wires, hardware, bicycles, handbags, food, footwear, clothing, and furniture.
