Premium synthetic blood penetration tester manufacturer? 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.

Testing to ASTM D4060 involves mounting a flat specimen to a turntable that rotates horizontally at a fixed speed. Two arms, each supporting an abrading wheel, are then lowered so that each wheel touches the surface. Before starting the test, a “suction arm” is lowered between the wheels to remove the abraded material from the sample’s surface. The turntable then starts rotating forcing rub-wear action of the wheels against the sample’s surface for the specified number of cycles or until a given mass of coating has been lost or until the wheels start exposing the substrate.
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.
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. See more info on https://www.gesterinstruments.com/.
