Bacterial filtration efficiency test manufacturer China? Bursting strength is an important physical index for evaluating fabric quality. In the process of use, the fabric is continuously subjected to the top and pressure of the concentrated load and expands until it is damaged, especially the elbows, knees and other parts of the clothing. This damage is called bursting. The common testing machines for bursting are Hydraulic Bursting Strength Tester and Pneumatic Bursting Strength Tester. Many customers are faced with a choice between these two testing machines. GESTER summarizes the similarities and differences of the two testing machines for easy reference.

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.
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.
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.
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.
