The equipment is mainly used to test the tensile strength performance of the helmet strap, and can control and measure the loading and displacement in the test. Conform to standard EN13087, GB811: 2010 and QCVN 02: 2008/BKHCN. It is widely used in the domestic and foreign helmet manufacturing industry and safety supervision and testing department.
