PVCu pipe – Subsurface disposal of effluent

Standard BNQ 3624-050
Unplasticized Polyvinyl Chloride [PVC-U] Perforated Pipe and Fittings - Pipes of 150 mm in Diameter or Smaller for Underground Dispersion of Effluents

Standard BNQ 3624-050 sets out the requirements relating to the dimensions, properties and testing methods for perforated pipe and its rigid fittings, manufactured from PVC compositions and used in gravity flow subsurface effluent disposal. It applies to rigid, smooth interior and exterior wall pipe and fittings, equipped with sockets for glued assembly. More specifically, it deals with rigid pipe and fittings used for the treatment of effluent from septic tanks by soil infiltration.

 

Certification Offer 

Manufacturers may ask the BNQ to recognize the conformance of their pipes and fittings with BNQ 3624-050. 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, including the location and dimensions of the perforations
  • Mechanical characteristics (rigidity, crush and shock resistance, quality of fusion bonding of co-extruded multiple smooth wall pipes)
  • Chemical resistance
  • Solar radiation protection
  • Verification of the PVC extrusion quality of the pipes
  • Verification of the moulding quality of PVC fittings 
  • Marking and handling

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