Steel Testing Lab in Bengaluru — Physical & Chemical Analysis

V2 Civil Diagnostics is a NABL accredited steel testing lab on Bagalur Main Road, Yelahanka, Bengaluru. We test TMT bars of all grades (Fe 415, Fe 500, Fe 500D, Fe 550D) per IS 1786.

IS 1786 requires tensile strength, yield strength, percentage elongation, and bend test for every lot of TMT bars. Chemical analysis (carbon, sulphur, phosphorus) is also required for grade compliance. Many QA/QC specifications additionally require the rebend test.

As per IS 1786, a minimum of three samples per diameter per heat/lot is required. Each sample should be at least 600mm long. Our team can advise on sampling based on the lot size.

Yes. We use optical emission spectrometry for accurate chemical composition analysis of carbon, sulphur, and phosphorus in steel samples.

Fe 500D has tighter chemical composition limits (lower carbon, sulphur, phosphorus) and a higher elongation requirement, making it more ductile. Our tests verify whether bars meet the specific grade's IS 1786 requirements.

Physical tests (tensile, bend, rebend) are typically completed within 2-3 working days. Chemical analysis results are usually available within 3-5 working days.
