European Pipe Standards Technical Specifications Considerations
| Pressure Rating (PN) | Calculated using MRS and SDR, adjusted by regional Safety Factor (C) |
|---|---|
| Material Strength | MRS (ISO, 50 yrs) vs. HDB (ASTM, 11 yrs) |
| Stiffness | PS (ASTM, psi or kPa) vs. STIS (ISO/EN, kPa) |
| Safety Factors | C=2-2.5 (UPVC EU/DE), C=1.4-1.6 (MPVC/PVCO), C=1.25-higher (PE) |
| Composition Limits | e.g., min PVC content in structured walls (EN vs AS/NZS), CaCO3 limits in foam core (ASTM F891) |
| European Pipe Coating | FBE, Powder coating, PVC coating, CTE, 3LPE |
| European Pipe Thread Standards | British Standard Pipe (BSP) |
| Dimensional Standard | EN 10220 |
