PVCu pipe and fittings – Pressure water supply and distribution

Pipes pvcu

Standard BNQ 3624-250
Unplasticized Polyvinyl Chloride [PVC-U] Pipe and Fittings - Rigid Pipe for Pressurized Water Supply and Distribution

This standard specifies the characteristics and test methods applicable to unplasticized polyvinyl chloride (PVC-U) socket ended pipe and injection moulded elastomeric gasketed fittings having nominal diameters of between 100 and 1500 mm, for use in drinking water systems and designed for pressurized water supply and distribution. These pipes and fittings may also be used in sewage backsiphonage systems.

Although this standard also concerns non-socket ended pipes assembled by fusion of the pipe ends on site, it does not specify such pipe assembly. This standard also provides information concerning pipe classifications and designations, pipe and fitting testing, quality control as well as marking and handling methods.

This standard does not apply to oriented polyvinyl chloride [PVC-O] pipe.

Manufacturers may ask the BNQ to recognize the conformance of their pipes and fittings with BNQ 3624-250. To obtain certification of their products, the manufacturers must prove they comply with the standard’s requirements.

General requirements:

  • Requirements related to thermoplastic (PVC)
  • General characteristics of the pipes and fittings
  • Assembly

Special requirements:

  • Dimensional characteristics
  • Mechanical characteristics (internal pressure, crush and shock resistance, tightness of joints)
  • Verification of the PVC extrusion quality of the pipes 
  • Verification of the moulding quality of PVC fittings 
  • Solar radiation protection
  • Characteristics of moulded fittings, manufactured from pipe ends and machined sleeves
  • Marking and handling

This certification program is accredited by the Standards Council of Canada.
