4 | Environmental stress crack resist (F50) | ISO 4599 | Min. 96h |
Physical and Mechanical Properties | |||
1 | Visual appearance | Visual inspection | Ribbed inside & smooth outside surface, free from blisters, shrink hole, flaking, scratches & roughness. |
2 | Outer diameter | FCST | 7.0mm ± 0.1mm |
3 | Wall thickness | FCST | 1.75mm ± 0.10mm |
4 | Inner diameter clearance | Blowing steel ball | A 3.0mm steel ball can be blown freely through the duct. |
5 | Ovality | FCST | ≤ 5% |
6 | Pressurization | 5 minutes @16bar each duct | No damage and leakage |
