Full title and description

ISO 16132:2024 — Ductile iron pipes and fittings — Seal coats for cement mortar linings. This International Standard specifies requirements for factory-applied seal coatings applied over cement mortar linings to the interior surfaces of ductile iron pipes and fittings, including performance and routine testing criteria for potable, irrigation and other agreed applications.

Abstract

This document defines performance requirements for seal coats used on factory-applied cement mortar linings of ductile iron pipes and fittings. It covers short-term sealing efficiency, long-term durability and behaviour under cyclic pressure, and it sets out routine tests for visual appearance, coating thickness and adhesion. The standard is intended for products for potable and irrigation water and for other uses as agreed between manufacturer and customer.

Scope

Specifies the requirements for seal coatings applied in the factory to surfaces of cement mortar linings on the interior of ductile iron pipes and fittings. The scope includes performance criteria (short-term sealing efficiency, long-term durability and cyclic pressure resistance) and routine production testing (visual appearance, thickness and adhesion). Applicability covers potable and irrigation water systems and other applications where manufacturer and customer agree.

Key topics and requirements

• Definition and intended use of seal coats applied over cement mortar linings for ductile iron pipes and fittings.
• Performance requirements: short-term sealing efficiency, long-term durability, resistance to cyclic pressure.
• Routine factory testing requirements: visual inspection, coating thickness measurement and adhesion testing.
• Application to potable and irrigation water systems and other agreed uses between manufacturer and customer.
• Replaces the previous edition ISO 16132:2016 (life-cycle update to Edition 3, 2024).

Typical use and users

Used by manufacturers of ductile iron pipes and fittings, quality-control and laboratory personnel, water utilities and engineers specifying pipeline materials, procurement teams and certification bodies. It supports product specification, factory quality control and conformity assessment for cement-lined ductile iron pipeline components.
