Pneumatic Bursting Strength Testing Machine For determining the bursting strength of woven or knitted fabrics, non-woven, paper, leather and board by application of a pneumatic load under a rubber diaphragm of a specific area. Provide with a digital readout of pressure with peak value hold facility, renewable rubber diaphragms, and manual clamping device with acrylic bell, forward reverse and neutral drive system. Provide accurate elongation information of fabrics, up to 0.1mm.
Correct use of computerized universal testing machine: Make sure all wiring is correct before the tensile testing machine is operated and preheat for at least 15 minutes to package the stability of the sensor. According to the test, the position of the upper and lower limit blocks is reasonably set to prevent the instrument from running over the stroke and causing damage to the fixture and the sample. When pressing the fast up button or the fast down button, do not put your hand between the moving beam and the fixed specimen, fixture or test device to avoid injury.
ASTM D4060 Taber Abrasion Testing: Taber rotary type abrasion tester is a specification that determines the “Abrasion Resistance of Organic Coatings by the Taber Abraser.” Although written for organic coatings, the same method applies to inorganic coatings. At the conclusion of testing the sample(s) are then re-weighed. The wear index is then calculated by taking the average mass loss per 1,000 cycles per section 12 of ASTM D4060. Assured Testing Services has multiple taber abrasion machines that meet the ASTM D4060 standard. One of our machines is shown with an exposed sample on this page.
The principle of testing that you should know: Stitch the sample with one or two pieces of specified multi-fiber adjacent fabric, which is placed in soap solution or other washing solution, mechanically stirred at the specified time and temperature, cleaned and dried. Taking the original sample as the reference sample, assess the discoloration of the sample by the left gray scale, and then assess the color stain of the adjacent fabric by the right gray scale.
