Overview of ISI Mark Certification for UPVC Soil & Waste Discharge Pipes (IS 13592)
IS 13592:2013 covers unplasticized PVC-U pipes used for soil and waste discharge systems inside and outside buildings, including ventilation, rainwater drainage, and rainwater harvesting systems. The standard applies to gravity flow applications and does not cover pressurized water supply pipes.
The standard specifies requirements for pipes with nominal outside diameters of 40, 50, 63, 75, 90, 110, 125, 140, 160, 180, 200, 250, and 315 mm. Pipes may be plain-ended or socket-ended and must demonstrate adequate mechanical strength, durability, and joint integrity.
The pipe material shall primarily consist of PVC resin with approved additives only. Pipes must successfully pass dimensional checks, visual appearance, reversion, stress relief, Vicat softening temperature, chemical resistance, impact resistance, and water tightness tests. Products are approved for ISI marking only after passing prescribed type, acceptance, and routine tests under BIS supervision.
