Dynamic Seam Fatigue Tester TF152
Seam Fatigue Tester, to determine the strength of upholstery seam constructions covering a standard foam composite cushion by imposing a cyclic, impact and penetrating load. Dynamic Seam Fatigue Tester complies with ASTM D4033, etc.
Dynamic Seam Fatigue Tester, is specially designed to test the strength of upholstery seam constructions covered by standard foam composite cushion by imposing a cyclic, impact and penetrating load.
A rubber-faced wheel of 127mm (5”) diameter impacts the fabric from a height of 150mm (6”) with a mass of 3.75 kg (8.25lbs), 25 times per minutes for 7000 cycles. Compressed air is required.

What is a Dynamic Seam Fatigue Tester?
Dynamic seam fatigue machine is made in accordance with the ASTM D4033 standard of “the standard test method for resistance to yarn slippage of furniture decorative fabrics—dynamic fatigue test method”, which is used to simulate the effect of load, force and pressure on furniture decorative fabric during use and used to test the dynamic fatigue resistance of the seams of sofa fabrics.
Dynamic seam fatigue test machine is suitable for testing the dynamic fatigue resistance of the seams of sofa fabrics. Fix a sample with a seam joint to a specimen seat containing an elastic foam pad, clamped on both sides, and use a free rotating rubber wheel of a certain weight, to impact the surface of the specimen continuously from a certain height, until the specified number of times to check the damage degree of the sample.
Why We Need Dynamic Seam Fatigue Test?
Dynamic seam fatigue testing machine is used for testing seam fatigue degree of automobile seats, domestic sofas and other surface materials. The surface materials (leather, synthetic leather, fabric, etc.) of sofa seat are stitching structure, the seam strength of connection and fatigue resistance for these materials directly affect the service life of the seat. We can predict the life effectively of the seat and provide reference value for improving the service life of the sofa seat by testing the strength and life of the material seam.
The dynamic seam fatigue tester produced by our company has simple operation and less daily maintenance. It supports six work stations to test at the same time, and the number of stations can be customized according to customer requirements. The instrument adopts caster wheel to support, which has flexible movement, convenient adjustment, and low noise when testing.
