Ductile iron pipes and fittings for pressure and non-pressure pipelines. Cement mortar lining Ingestion-build-232773 DD IEC/PAS 60539-1-1 provides a1 Scope This International Standard specifies the nature, the method of application, the surface condition and the minimum thickness of internal linings of cement mortar for ductile iron pipes and fittings for pressure and non pressure pipelines as defined in ISO 2531 and ISO 7186. It covers cement mortar linings which are used to improve the hydraulic properties of pipes and fittings compared to un lined pipes and fittings and or to prevent corrosion
