Frequently asked questions
Is TCR Engineering BIS-accredited for rebar coupler testing?
Yes. TCR Engineering is the first BIS-accredited commercial laboratory in India for IS 16172 rebar coupler testing, covering all diameters from 8 mm to 40 mm (BIS reference LRMD/LRS/OSL-7103506). The coupler scope spans tensile strength, disengagement, elongation, slip, cyclic tensile and fatigue testing.
Which coupler tests does TCR perform under IS 16172?
The laboratory performs coupler tension and uniform elongation, slip measurement, cyclic tension-compression reversal, and low- and high-cycle fatigue under IS 16172. TMT rebar from the same splice assembly is tested for tensile, elongation, bend and re-bend properties per IS 1786, and bond by pull-out test per IS 2770 Part 1.
Does the BIS-recognised scope cover materials beyond couplers?
Yes. The BIS-recognised civil scope also covers reinforcement bar per IS 1786 and IS 16651, structural steel per IS 2062, carbon-steel sheet per IS 513 and IS 1079, and water and sewage pipe per IS 3589. High-tensile strand for high speed rail and bridges is tested per ASTM A416 and IS 14268.
