Labor protection shoes SATRA Ross flexure tester (STM 141) Bata band test if the sole contains large splints or complex design of different materials, then the best way to resist the crack resistance of SATRA test is the Bata belt tester. This is a generally accepted test which can reproduce the results related to actual wear. Attach the front part of the whole sole (minus the heel but still contain any cavity filler or midsole material) to the canvas belt. This part is driven by the driven mandrel with different diameters, so when the belt is driven to the mandrel, the sole is recycled and flexed repeatedly. The general diameter of the spindle is 90 millimeters, but it can be changed to 60 millimeters or 120 millimeters to increase or decrease the degree of deflection. Unlike the Ross flexure test, it is not necessary to cut the sole. The test runs for 50000 cycles, and continuous visual assessment is carried out during operation. Record the length and depth of any crack. The test is usually carried out at room temperature, but at SATRA, the shoe sole can be tested at a temperature of -15 degrees. The Bata belt (STM 459) is equipped with three replaceable follower spindles of 60 mm, 90 mm, and 120 mm, with a rotation speed that produces 90 deflections per minute on a smaller axis. You can also provide a lower temperature version of the machine to perform tests at temperatures below -20 degrees.
