GB/T 17200-2008 formulates technical specifications for tensile, pressure and bending testing machines (constant speed drive) for rubber and plastics. The standard specifies the technical requirements of the testing machine, such as force value accuracy, displacement Measurement accuracy, speed control accuracy, etc., to ensure the accuracy and reliability of the test data. The structural design and manufacturing materials of the testing machine are also stipulated to ensure the Stability and durability of the equipment. At the same time, the installation, commissioning and inspection methods of the equipment are standardized. This standard provides a basis for the production, purchase and use of such testing machines, and helps the rubber and plastics industry to accurately test mechanical properties and promote the mass improvement of products in the industry.
