Every batch of ISI Marked Rigid uPVC Conduits are tested at our inhouse laboratory as per the Scheme of Testing and Inspection laid down by the Bureau of Indian Standards under IS 9537 (Part 1) 1980 and IS 9537 (Part 3) 1983. Testing of the conduits are regularly conducted at CIPET / Central Electrical Testing Laboratory (Both Government of India Laboratories) for 3 rd party certifications.
FRLS properties of the conduits are regularly conducted at CIPET/ CPRI (Both Government of India Laboratories) for 3rd party certifications.
Material Test Certificates are issued with every supply along with the invoice, which mentions Quality date, Invoice number and place of supply.

Thickness
- The wall thickness in PVC conduits is available in ranges from 1.2mm, 1.5mm, 1.8mm, 2.0mm, 2.2mm upto 3.28mm according to the diameter and as per IS specification.
- M.S.conduits are available in wall thickness of 20g / 18g / 16g and 14g
Comparison between PVC and Metal Conduits
Cost
- Low Cost:
- PVC conduits are less costlier than M.S conduits by about 130 % approx. They are light in weight, Can be joined permanently with leak proof installation by applying PVC solvent easily in no time and less labour resulting in substantial cost savings and also helps in early completion of time bound projects. If required PVC conduits also can be threaded easily.
- High Cost:
- Due to the base price of Mild Steel, Weight, Transportation (from Punjab) and Labour element, the cost of M.S/GI Conduits is much higher. Threading and installation requires high amount of labour and time resulting in high cost.
Physical / Chemical Properties
- Inner and outer surface of PVC Conduits are smooth, free from burrs, flash and similar defects
- F.R.L.S :- Fire retardant, Low Smoke and Rat retardant PVC conduits are also available. PVC is self extinguishing and does not promote fire. PVC Conduits have good mechanical and thermal properties as well.
- PVC conduits are available in various colours for colour coding of wiring to have a distinct identification.
- Tensile Strength : 492 / 562 Kg/cm2.
- Specific Gravity : 1.35 – 1.45 g/ml
- Metal fissures are likely to damage the cables and wires.
- M.S Conduits are Fire and Rat Retardant, having good mechanical and thermal properties
- Metal conduits are available only in black stove enameled colour and some conduits are not painted on the inner surface leading to early corrosion.
- Tensile strength: Good
- Specific Gravity : Not known
