Shenzhen metal impact test is good, I recommend amp detection, worthy of your trust!
Impact test is a test method to determine the safety, reliability and validity of the products when the military or civil equipment is subjected to external force. Impact test in electrical engineering, including the operation impact test, lightning impulse test, steep wave front impact test, test the insulation strength of electrical equipment.
Test classification
Impact test is divided into three kinds: 1, the provisions of pulse test method, using sine wave test; 2, shock spectrum test method; 3, the provisions of the test machine test method.
According to the temperature, the impact test is divided into:
Impact test at room temperature, in the normal temperature test, generally in the range of 23 + 5.
Low temperature impact test; in the low temperature medium to keep a certain time, so that the temperature reached the requirements of the rapid removal after the completion of the impact test.
1 the use of medium can be a mixture of ice water (0 degrees Celsius)
2 other temperature can be used at low temperature, according to different temperatures, can be used for the heat preservation of alcohol or liquid nitrogen.
Main equipment:
(Charpy impact test machine and a drop hammer impact test machine): manual, semi automatic testing machine, automatic impact testing machine.
