CEN/TC 203/WG 8 - Coatings for pipes, fittings and accessories

This document specifies the requirements and test methods applicable to factory applied internal lining made of thermoplastic acid modified polyolefin (TMPO) for the heavy duty corrosion protection of ductile iron pipes conforming to EN 545, EN 598 and EN 969. This document also applies to pipes with only socket and spigot ends coated with TMPO. Fittings and accessories are covered separately by EN 14901-2.

This document specifies the requirements and test methods applicable to factory applied extruded polyethylene coatings for the external corrosion protection of ductile iron pipes according to EN 545, EN 598 and EN 969 for use at operating temperatures up to 50 °C.
This document is not applicable to ductile iron pipes protected with thin PE sleeve. Special works at site like drilling, tapping, etc. can influence the corrosion protection properties. Those job steps are intended to be included in the instructions of pipe saddle and accessory manufacturers and all other essential installation instructions. These instructions are not part of this document.

This document defines the requirements and test methods for factory applied thermoplastic acid modified polyolefin (TMPO) coatings used for the protection of ductile iron fittings and accessories according to EN 545, EN 598, EN 969, EN 12842 and EN 14525:
-   conveying water (e.g. potable water, raw water, …) at operating temperature up to 50 °C; or
-   conveying waste water at operating temperature up to 45 °C; or
-   conveying gas at operating temperature up to 50 °C;
-   suitable for external environments, i.e. soils, waters and atmospheres of all common corrosion loads, characterized in D.2.3 of EN 545:2010.
