Velcro Closing Tester is intended to press the two parts of the touch and close fastener together under controlled conditions, prior to determining the peel and shear strength.
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.
