Grates, Covers, Frames, Catch Basin Traps and Valve Boxes — Grey-Iron and Ductile-Iron Castings
Standard BNQ 3221-500 Grates, Covers, Frames, Catch Basin Traps and Valve Boxes — Grey-Iron and Ductile-Iron Castings for Civil Engineering Work — Characteristics and Test Methods
The standard BNQ 3221-500 includes the cast iron parts most used in the municipal sewer and drinking water distribution networks in Québec. The quality and uniformity of these products depend on standardization.
The standard specifies the physical, mechanical and dimensional characteristics of grates, covers, frames and catch basin traps made of grey iron or ductile iron, installed on manholes or catch basins, and valve boxes made of grey iron or ductile iron installed on drinking water conduit valves.
The standard BNQ 3221-500 serves as a reference for conformity assessment activities.
