BIS ISI Certification for HDPE Pipes for Potable Water Supplies – IS 4984
BIS ISI certification is mandatory for High Density Polyethylene (HDPE) pipes used for potable water supplies in India as per Indian Standard IS 4984:1995. HDPE pipes play a crucial role in drinking water distribution systems due to their superior durability, flexibility, corrosion resistance, and chemical stability. Without a valid BIS ISI license, manufacturers and importers are not legally permitted to manufacture, import, or sell HDPE pipes for potable water applications in India.
IS 4984:1995 ensures that HDPE pipes meet stringent quality and safety requirements through rigorous testing of parameters such as density, tensile strength, elongation at break, hydrostatic pressure resistance, impact strength, and environmental stress cracking resistance. These tests ensure long-term performance and safe delivery of drinking water under varying pressure and environmental conditions.
BIS ISI Mark certification enhances product credibility, ensures statutory compliance, and builds confidence among government authorities, water supply boards, infrastructure developers, and end users across India.
