ISO 4427 Plastics Piping Systems Certification
Polyethylene (PE) Pipes & Fittings | Hydrostatic Pressure Testing | Water Supply Standards
Certify polyethylene (HDPE / MDPE) pipes and fittings for municipal water supply and industrial gas distribution with accredited ISO 4427 compliance consulting. We guide pipe extruders and fitting manufacturers through hydrostatic strength testing, melt flow rate (MFR) validation, carbon black dispersion, and international water utility empanelment.
ISO 4427 specifies requirements for piping systems made from polyethylene (PE) intended for human consumption water conveyance, raw water, and general pressure drainage. Our technical team assists in establishing in-house laboratory controls and third-party NABL test verification.

Frequently Asked Questions
-
Both standards govern Polyethylene (HDPE) pipes for water supply; ISO 4427 is the international standard required for export markets and multilateral funded projects (World Bank, ADB), while IS 4984 is the mandatory domestic Indian Standard under BIS.
-
SDR (Standard Dimension Ratio) is the ratio of the pipe's outside diameter to its wall thickness. A lower SDR (e.g. SDR 9 or SDR 11) indicates thicker walls and higher pressure resistance compared to a higher SDR (e.g. SDR 21).
-
OIT measures the thermal antioxidant protection in the pipe material. An OIT >= 20 minutes ensures that the pipe will not degrade during extrusion and will maintain its mechanical strength for 50+ years underground.
-
No, ISO 4427 strictly mandates the use of virgin PE compound or clean in-plant reprocessable material from the manufacturer's own production of the same grade. External post-consumer scrap is completely prohibited.
-
The certificate is valid for 3 years, subject to annual surveillance testing and factory audit.
