CFT Crumple Flex Tester
The CFT Crumple Flex Tester determines the resistance of coated fabrics to damage by repeated flexing, providing a reliable reference for improving fabric quality. It operates with 4 test positions fitted with Φ63.5 mm discs (15 mm wide) that rotate at 200±10 r/min through a 90°±2° rotation angle.
Specimens are cylindrical in shape, measuring 220×190 mm flat, sewn to a length of 190 mm with an inner diameter of Φ64 mm. The compression mechanism runs at 152±4 r/min with a 70 mm stroke, and the distance between the inside faces of the two disc flanges is a maximum of 180±3 mm.
The test count is digitally settable from 0 to 999,999 cycles. The instrument conforms to ISO 7854 Method C and BS 3424. It requires a single-phase 220V 50Hz 3A power supply, measures 550×400×400 mm (W×D×H), and weighs 65 kg.

Key Highlights
4-Position Simultaneous Testing
Four test positions with Φ63.5 mm discs allow multiple specimens to be evaluated in a single test run, improving throughput and consistency.
Settable Count up to 999,999
Digital counter is freely settable from 0 to 999,999 cycles, enabling precise control of test duration for a wide range of fabric evaluations.
ISO 7854 & BS 3424 Compliant
Conforms to ISO 7854 Method C and BS 3424 standards, ensuring results are internationally recognised for coated fabric flex resistance testing.
It determines the resistance of coated fabrics to damage by repeated flexing, providing a reference for improving fabric quality and durability.
The CFT has 4 test positions, each fitted with Φ63.5 mm discs (15 mm wide), allowing multiple specimens to be tested simultaneously.
Rotation speed is (200±10) r/min (3.33Hz±0.17Hz) through a 90°±2° angle. Compression speed is (152±4) r/min (2.53Hz±0.07Hz) with a 70 mm stroke.
The counter is digitally settable from 0 to 999,999 times, allowing precise control over the number of flexing cycles applied during the test.
The flat specimen dimensions are 220×190 mm. It is sewn into a cylindrical shape with a length of 190 mm and an inner diameter of Φ64 mm.
The CFT Crumple Flex Tester complies with ISO 7854 Method C and BS 3424.
Power supply: 1∮ AC 220V 50Hz 3A. Dimensions: 550×400×400 mm (W×D×H). Weight: 65 kg.
The maximum distance between the inside faces of the two disc flanges is 180±3 mm.
