Overview

Every mandatory pipe certification test in one lab

Plastic pipe manufacturers are certified against demanding national and international standards — IS 4985 for PVC, IS 4984 for HDPE, IS 15801 for PPR, plus ISO 1167 hydrostatic long-term testing that predicts 50-year performance. Missing even one test method blocks BIS licence renewal.

This solution assembles the complete certification bench a PVC, HDPE, PPR or CPVC pipe producer needs — from hydrostatic pressure and cold impact for finished pipe to MFI, VSP, carbon black content and OIT on incoming resin and finished wall. Manufactured in Mumbai since 1971 and used by pipe plants across India and 50+ export markets.

FAQ

Frequently asked questions

Which BIS standards does IS 4985 relate to for PVC pipes?

IS 4985 is the primary Indian standard for uPVC pipes for potable water; it references hydrostatic (ISO 1167 method), falling weight impact, longitudinal reversion, Vicat softening and specific gravity tests as mandatory.

How long must the 1000-hour hydrostatic test run without interruption?

1000 hours continuous at the specified elevated temperature and hoop stress. Any interruption invalidates the test — professional panels use uninterrupted power and pressure control accordingly.

Do PPR pipes need OIT testing?

PPR long-term specifications require OIT for oxidative-durability verification — the value predicts hot-water service life under stress.

Can one certification bench serve PVC + HDPE + PPR production simultaneously?

Yes — hydrostatic, impact, tensile and thermal testers are common. Only carbon-black and OIT are HDPE-specific and even those are useful across product lines.
