Roughness Test
After the surface is finished by mechanical polishing, the roughness measurement (RA) must be applied in longitudinal direction. Moreover, this measurement must be a matter of agreement with our customers.
We test a sample from the first tube from a batch and compare it to the specimen.
- If the sample passes, continue polishing. Thereafter, all of them must be measured in roughness test.
- If the sample doesn’t pass, readjust the machines, re-polish the sample and re-test.
* This test is for demonstration on web page only! Please be informed that all tests are under ASTM Standard. For more information, please contact us.
