Ductile Cast Iron Piping and Joints – Drinking Water and Sewer Line Systems

Ductile-Iron Pipe

Standard BNQ 3623-085
Ductile Cast Iron Piping and Joints for Drinking Water and Sewer Line Systems – Characteristics and Test Methods

Manufacturers of ductile iron pipe for pressure water pipelines must take a significant number of elements into consideration to ensure to provide a uniform, safe product. Standard BNQ 3623-085 addresses this need by establishing the general and specific requirements related to the physical, mechanical and dimensional properties of ductile iron pipe to be used in pressure water pipelines of a diameter from 75 mm to 1,600 mm for pipes with bell-and-spigot joints and a diameter of 75 mm to 600 mm for pipes with a mechanical seal. BNQ 3623-085 serves as a reference to evaluation of pipe compliance. It also provides indications regarding sampling, testing methods and control methods applicable to ductile iron pipe (control of dimensional properties, testing methods and compliance control) and marking.
