Significance and Use: Fabric Pneumatic Bursting Tester method for the determination of diaphragm bursting strength of knitted, nonwoven and woven fabrics is being used by the textile industry for the evaluation of a wide variety of end uses. universal testing machine compression test : tensile test generally involves clamping the two ends of the material sample on two fixtures separated by a certain distance. The two clamps separate and stretch the specimen at a certain speed. The change in stress on the sample is measured until the sample is destroyed. The tensile test of the tensile machine is one of the most widely used methods for studying the mechanical strength of materials, and it is necessary to use constant speed motion.
Correct use of computerized universal testing machine: When the electronic stepless speed regulation adjusts the lifting speed, it cannot be operated too fast. Before using the 50KN power machine, pay attention to check the tightening of the clamp tightening screws. When lifting the lower clamp, the movement should be stable, avoid collision, and often check the tightness of the clamp screw. When replacing the test fixture, pay attention to cooperate to prevent bruises.
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.
