IS 16172 rebar coupler testing
The Indian standard for the couplers that join reinforcing bars — required on metro, bridge and building projects.
IS 16172, for buyers
Coupler makers, contractors and project consultants
That the joint is as strong as the bar, doesn't slip, and survives repeated and earthquake-like loading
Results as soon as each test ends; the report within a working day.
IS 16172
The Indian Standard for mechanical couplers that splice reinforcing bars — static strength, slip, cyclic tensile, and high- and low-cycle fatigue.
DSRI runs the IS 16172 series on its 2,500 kN and 2,000 kN machines, including large-diameter bar, reported under the NABL symbol.
Typical products. Mechanical rebar couplers and splices, on the customer's own bar.
NABL accredited testing laboratory vide certificate no. TC-12060 (ISO/IEC 17025:2017). Lines below are in the scope of accreditation and are reported under the NABL symbol; tailored profiles and methods outside the scope can usually still be run and are reported as non-accredited.
