Foam Constant-load Pounding Fatigue Tester Determine the thickness reduced value and hardness decreased value of porous elastic materials used in interior decoration.

Seam Fatigue Tester is the measurement of failures in the three most commonly used upholstery seams - warp sewn to warp (wale to wale), filling sewn to filling (course to course), and warp sewn to filling (wale to course).

The purpose of this test is to determine: (1) retention of load bearing (65 % IFD), (2) a loss in thickness, and (3) structural breakdown as addressed by visual inspection. This procedure describes tests that evaluate the specimen by repeatedly deflecting the carpet cushion by a 152 mm diameter and 152 mm wide rubber covered roller exerting a force of 266±5N on the test specimens.
