Charpy影响测试

1. Functions The instrument is mainly used for the determination of impact toughness of the nonmetal materials including rigid plastic,reinforced nylon,glass steel,ceramics,cast stone,electric insulating materials and so on. It is the ideal testing devices for the departments including the chemical industry,research institutes,universities,quality inspection and so on. 2. standards-compliant 2.1 EN ISO179 Determination of Charpy impact properties 2.2 ISO 9854 thermoplastics pipes for the transport of fluids - Determination of pendulum impact strength by the Charpy method 2.3 GB/T 18743 Thermoplastics pipes for the transport of fluids-Determination of impact by the charpy method 2.4 GB/T 1043plastic- charpy impact test method 3.
