Shorter tests provide an idea of how much firmness a foam may lose through initial use, while longer tests provide data on overall foam durability. ROLLER SHEAR. A particularly severe flex fatigue test is roller shear, where a rolling weight is run over a foam sample from two directions, typically for about 25,000 cycles.The Foam Compression Tester is used to test the compression quality of foam. The instruments tests as per ASTM D3754 standard including others. Skip to Content; Main Menu; Search +61 3 9708 6885 [email protected]
Significance — The data obtained from a compression test may include the yield strength, the yield point, Young's modulus, the stress-strain curve, and the compressive strength (see Terminology E6).In the case of a material that does not fail in compression by a shattering fracture, compressive strength is a value that is dependent on total strain and specimen . 4.1 Compression set tests are intended to measure the ability of rubber compounds to retain elastic properties after prolonged action of compressive stresses. The actual stressing service may involve the maintenance of a definite deflection, the constant application of a known force, or the rapidly repeated deformation and recovery resulting from intermittent .
