Eye hooks are critical fittings used with dead-end and suspension clamps to support Aerial Bundled Cable lines. They carry both mechanical load and environmental stress, so every piece must be tested before installation.
Eye hooks hold the entire weight and tension of the cable during and after installation. If one fails, the line can drop or break, creating serious safety risks on site. The Tensile Test ensures the hook can handle this load without bending or breaking. The Galvanizing Test ensures the zinc coating protects the hook from rust and corrosion, keeping it reliable for years in outdoor conditions.
In this blog, you will learn how to perform the Tensile and Galvanizing Tests on eye hooks – the Mechanical (Load) Test as per IS 2486 Part 1 and REC-35, and the Galvanizing Test as per IS 2633.
Note: Please use proper tools, procedures and personal protective equipment to avoid injury.
Tensile Test
Step 1: Mount the eye hook in the tensile testing machine with the load aligned to the hook axis. Tighten the grips and ensure it is securely held in the fixture.
Step 2: Apply the load gradually up to 2000 kg. Hold for 1 minute. The eye hook passes the test if there is no visible deformation, cracking, or fracture.
As you can see, the Axis eye hook successfully passed the test without any visible damage.

Galvanizing Test:
Step 2: Test solution should be prepared as per IS 2633. The specific gravity of the solution shall be 1.186 at eighteen degrees Celsius, plus or minus two degrees. Then immerse the sample completely in the test solution for one minute.
Step 3: Then rinse it in clean running water and wipe it dry with a soft cloth. Repeat this process for 4 successive dips, each lasting for 1 Min.
Step 4: The material passes this test if, at the end of the specified number of dips, when the test piece is finally rinsed and wiped dry, it does not show any adherent red deposit of copper upon the base metal.
Congratulations, you have successfully completed the test.
We hope you now have a clear understanding of how to conduct Tensile and Galvanizing test. At Axis, every eye hook is tested for both mechanical strength and galvanizing quality in our NABL accredited in-house testing lab. We never compromise on quality, which is why millions of Axis AB Cable Accessories are installed across the world.
