Polymer, Pipes & Fittings Testing FAQs
Which BIS IS standards apply to polymer pipes and fittings?
- UPVC pipe — IS 4985
- SWR pipe — IS 13592
- Casing/Screen pipe — IS 12818
- PVC Sewerage (non‑pressure) — IS 15328
- HDPE (water supply) — IS 4984
- HDPE Sewerage (up to 20–2500 mm) — IS 4984
- HDPE Sewerage (> 2500 mm) — IS 14333
- PPR — IS 15801
- CPVC — IS 15778
- CPVC fittings — IS 17546
- PVC‑U fittings (water supply) — IS 7834
- SWR fittings (PVC‑U) — IS 14735
Note: For gravity sewer applications, PVC‑U (IS 15328) and HDPE (IS 14333) are both used depending on client specifications and site conditions.
What key tests are required for BIS compliance?
- UPVC (IS 4985) — Dimensions; Hydrostatic (ambient/elevated); Opacity; Heat reversion; Impact (TIR); Flattening; VST.
- SWR (IS 13592) — Dimensions; Impact; Heat reversion; VST; Joint water‑tightness; Visual.
- Casing (IS 12818) — Dimensions; Hydrostatic; Collapse; Tensile of threaded joints; Impact; Thread gauging.
- PVC Sewerage (IS 15328) — Dimensions; Ring stiffness/flexibility (as applicable); Impact; Heat reversion; VST; Joint water‑tightness.
- HDPE (IS 4984) — Dimensions/SDR; Hydrostatic (20 °C and elevated); Density; MFR; Carbon black content/dispersion; OIT; ESCR; Tensile; Visual.
- HDPE Sewerage (IS 14333) — Dimensions; Density; MFR; Carbon black; OIT; Leak‑tightness; ESCR; Visual.
- PPR (IS 15801) — Dimensions; Hydrostatic at multiple temperatures (20–95 °C as grade/class); MFR; Thermal stability (e.g., OIT); Longitudinal reversion.
- CPVC (IS 15778) — Dimensions; Hydrostatic (ambient/elevated); VST; Heat reversion; Impact (as applicable); Visual.
- CPVC fittings (IS 17546) — Sustained and burst pressure; Thermal cycling/leak‑tightness; Dimensions/marking.
- PVC‑U fittings (IS 7834) — Dimensions; Hydrostatic/leak tightness; VST; Heat reversion; Impact; Visual.
- SWR fittings (IS 14735) — Dimensions; Impact; VST; Heat reversion; Water‑tightness; Visual.
Which testing machines do you supply for these standards?
- Hydrostatic Pressure Test Apparatus (multi‑station) with temperature control
- Falling Weight Impact Tester (TIR) for PVC/CPVC/HDPE
- Ring Stiffness/Flexibility Test Rigs (non‑pressure sewer pipes)
- Heat Reversion and Oven aging setup
- Vicat Softening Temperature (VST) Tester
- Melt Mass‑Flow Rate (MFR) Tester
- Carbon Black Content Furnace and Dispersion kit (microscopy)
- DSC for Oxidation Induction Time (OIT)
- Universal Testing Machine (UTM) for tensile/ESCR fixtures
- Leak‑tightness/Joint testing rigs (solvent weld, rubber ring, butt/electrofusion)
Why are ESCR, OIT and Carbon Black tests critical for HDPE?
They assess long‑term performance: ESCR checks resistance to slow crack growth; OIT measures antioxidant stability; Carbon black content/dispersion ensures UV resistance and uniformity — all essential for durability in service.
What is the difference between SWR (IS 13592) and sewer pipes (IS 15328)?
IS 13592 covers PVC‑U SWR pipes for soil/waste/rainwater within building plumbing, emphasizing impact/VST/reversion and watertight joints. IS 15328 covers non‑pressure sewerage/drainage pipes, adding ring stiffness/flexibility for underground loads.
