Non-metallic tension, pressure, and universal testing machine mainly comprises small load testing machine, testing machine small force value to And leather, paper, rubber, plastics, fiber and other non-metallic materials testing machine.2 CitationsCitation of this Regulation as follows. GB/T 16825.1-2002/ISO 7500-1.1999 "static uniaxial testing machines - the first part of Rally And (or) pressure testing machine measuring system test and calibration " GB/T 2611-1992 "Test General technical requirements" GB/T 17200-1997 "rubber plastic tensile, compression, bending test machine technical requirements" GB/T 13783-1992 "Cotton fibers - Determination of breaking strength of flat bundles" JJG 762-2007 "extensometer test procedures" Should pay attention to the use of this procedure by using the currently valid version of the documents cited.3 Overview3.1 Structure and Principle According to the measurement and drivers of different ways, testing machine may have a different structure and principles of work, the main Afterburner systems, measurement systems, safety devices and other components. How it works. afterburner system applied to the specimen test Force measurement system test force, the specimen deformation and test operation. 3.2 Purpose Tensile testing machine is mainly used in non-metallic materials and products, compression measuring performance. With about accessories, also It can be used to test materials and manufactures bending, shear, bending, peeling and other special properties.4 metering performance requirements4.1 Test force measuring system 4.1.1 Classification and Index test force testing machine shall conform to the technical requirements in Table 1.
