JB-300 type impact test machine

bargain

JB-300 type impact test machine used to measure the impact resistance properties of metallic materials under dynamic load, in order to determine the nature of the material under dynamic load. The test machine in accordance with national standards GB / T3808-2002 ( Charpy impact test machine testing ) development and production, according to the national standard GB / T229-2007 ( metal Charpy pendulum impact test methods) of metal material impact test, the maximum impact energy of 300J, and 150J comes with a pendulum, the use of a sample cross section is 10 * 10mm ; testing machine has a larger impact energy, so the main test for greater impact toughness ferrous metals, such as steel and alloys before the use of pendulum impact tester impact after remaining potential energy and potential energy 're just in the dial. on display out of the way, get absorbed energy of the sample.
