Discription
Accurate Ring Crush Strength Testing for Paper and Paperboard
4B Testing Equipments Pvt. Ltd. offers a high-quality Digital Ring Crush Tester (RCT) designed to determine the ring crush strength and compression resistance of paper, paperboard and packaging materials. The machine measures the maximum compressive force required to crush a test specimen formed into a ring.
The Digital RCT Tester is widely used in paper mills, corrugated box industries, paperboard manufacturing units, packaging industries and quality control laboratories. It helps manufacturers evaluate the strength, stiffness and load-bearing performance of paper and board materials.
The Digital Ring Crush Tester can be configured according to applicable standards such as:
- ISO 12192 – Ring crush resistance of paper and board
- TAPPI T 822 – Ring crush of paperboard
- TAPPI T 818 – Ring crush of paper
- ISO 3037 – Edgewise crush resistance of corrugated fibreboard
- ASTM D4577 – Compression resistance of paperboard
- Applicable IS/BIS standards
The test fixture, sample dimensions and machine configuration should be selected according to the applicable test standard and material type.
