SATRA TM 92 Advantages & Shortcomings
SATRA TM 92 is a technical standard for flexural testing issued by the British SATRA Technical Research Center. SATRA is one of the main makers of technical regulations on footwear in the European Union. Test conditions: flexing frequency 140±10 times/min, flexing angle is It depends on the style of the shoes, such as men's shoes, women's shoes, children's shoes, flat-soled or uneven-soled shoes, the flexion angle is different, and the clamping distance is determined according to the shoe size.
Through actual testing, the standard method has the following advantages:
(1) This testing standard is applicable to any type of shoes, such as children's shoes, men's shoes, women's shoes, sandals or boots, flat or uneven bottoms, laced or unlaced shoes, with a wide range of applications.
(2) The shoe flexural test is back-lifting (the heel is upward), which is the same as when the heel is lifted up when a person is walking, so that the effect of a person's walking can be more realistically imitated.
(3) When testing children's shoes, men's shoes, and women's shoes, the test distance and the test angle of each number are different. The test distance for children's shoes is relatively short; the test angle is also relatively small. The test distance of the corresponding men's shoes is relatively long, and the angle is also relatively large. The method is more scientific.
(4) At present, the detection equipment that meets the standard of this method has less noise and is more suitable for use in places where noise is afraid of interference. In addition, a protective cover is installed on the top of the instrument to help protect the safety of test personnel.
In the test process, it is concluded that the method has the following shortcomings:
(1) When testing, first draw a line, then determine the clamping distance according to the standard, and then adjust the required test angle. The test angle of each sample is the same, so the test angle must be re-adjusted each time, which is more cumbersome.
(2) The detection speed of this method is relatively slow, and its supporting instruments are currently used in departments, especially not many manufacturers, and not many companies that understand the standard. The instrument is relatively expensive.
