- Environmental testing
- High Temperature Test: Put it into a 80-degrees drying oven for 12 ساعات, no shape deformation . After drying for 24 hours at normal temperature, there is no oxidation.The characteristic test is in following table:
- Low Temperature Test: Put in into a -40-degrees freezer for 12 ساعات, no shape deformation. After recovering at normal temperature, no oxidation and rust formation. The characteristic test is in following table:
| لا. | Normal temperature performance | High temperature test performance deviation | Low temperature test performance deviation |
