Scope

This European Standard defines the requirements and test methods for factory applied thermoplastic acid modified polyolefin
(TMPO) linings and coatings used for the corrosion protection of ductile iron fittings and accessories conforming to EN 545,
EN 598, EN 969, EN 12842, EN 14525, for:
— conveying water (e.g. potable water) at operating temperature up to 50 °C excluding frost; or
— conveying waste water at operating temperature up to 45 °C excluding frost; 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.
