Specifies the manufacturing requirements, dimensions, and testing methods for high-density polyethylene (HDPE) pipes used in potable water supply systems. The 2016 revision phases out PE 63, emphasizing PE 80 and PE 100 materials, and formally aligns pressure ratings (PN) with Standard Dimension Ratios (SDR).
Specifies requirements for HDPE pipes used for conveying potable water.
Quick Reference Values
carbon black content2.0% to 2.5% by mass
mrs pe 10010 MPa (Minimum Required Strength)
mrs pe 808 MPa (Minimum Required Strength)
design coefficient c1.25 minimum for water at 20°C
melt flow rate deviation± 20% max deviation from raw material
standard length of straight pipes6 m or 12 m (unless supplied in coils)
Key Formulas
SDR = dn / en (Standard Dimension Ratio = Nominal Outside Diameter / Nominal Wall Thickness)
PN = (10 * MRS) / (C * (SDR - 1)) (Relationship between Nominal Pressure, Minimum Required Strength, Design Coefficient, and SDR)
Practical Notes
PE 63 is considered obsolete for potable water applications in the 2016 revision; always specify PE 80 or PE 100.
A lower SDR corresponds to a thicker pipe wall and a higher pressure rating (PN).
Blue colored pipes or black pipes with blue longitudinal stripes are the standard identification for potable water lines.
Pipes supplied in coils are typically limited to smaller diameters (up to 110mm) depending on SDR, to prevent kinking.
