Ductile-Iron Pipe and Compact Fittings, and Gray-Iron or Ductile-Iron Castings for Civil EngineeringWorks – Certification Protocol
The purpose of this document is intended to establish a certification protocol for ductile-iron pipe
and compact fittings, and gray-iron or ductile-iron castings (manhole frames, grates, covers,
cesspool traps and valve boxes) for civil engineering works, according to the requirements of
Standards AWWA C153, NQ 3221-500 and NQ 3623-085.
NOTE — Standard AWWA C153 on ductile-iron compact fittings is only published in English. Standard
NQ 3221-500 on gray-iron or ductile-iron castings (manhole frames, grates, covers, cesspool traps and
valve boxes) for civil engineering works is only published in French. Standard NQ 3623-085 on ductileiron
pipe for water pressure piping systems is published in both French and English. In case of
incompatibility, the French version prevails.
This document is for manufacturers seeking to have the conformity of their products recognized by
the Bureau de normalisation du Québec (BNQ).
It is important to note that at the time of publication of this protocol, the document Certification
