| Ceramics Saddles Testing Rule |
1.Fragmentation
Disqualification if more than 30% of the rings in a batch were broken; Disqualification if more than two places of a ring were broken.
2.Interstice
Disqualification if the interstice was wider than 0.8mm; Disqualification if there’s more than two interstices in a ring.
3. Chromatism
Disqualification if there’s more than 50% of rings in a batch had chromatism or smutch.
4. Felt
Disqualification if the rings felt together; Numbers of rings felt together should not above 0.5% of the package.
5. All the disqualified rings should not above 10% of the package.
6.Eyewinker, shiver and dust should not above 1% of the package.
7. Size
Length + width + height should be in the standard area, thickness also should be in the standard area, either of the above mentioned two items exceed the standard area should not above 20% |
