Fitting Physical Properties
| Items | Property | Demand |
| 1 | Extension Rate at Break, % | ≥350 |
| 2 | Longitudinal Reversion (100°C), % | ≤3 |
| 3 | Oxidation Induction Time (210°C), min | ≥20 |
| 4 | Melt Mass-Flow Rate | The change rate of pipes and raw materials shall not exceed 25% |
| 5 | Static Hydraulic Pressure Test | 20°C, 100h PE100, 12.0Mpa; No crack or leakage |
| 80°C, 165h PE100, 5.4Mpa; No crack or leakage | ||
| 80°C, 1000h PE100, 5.0Mpa; No crack or leakage | ||
| Note: The static hydraulic pressure test at 80°C for 165 hours only considers brittle failure. If ductile failure occurs during the test time, select the lower ring stress according to the standard and retest according to the corresponding minimum failure time. | ||
