TMT & Rebar Manufacturing
IS 1786 compliance testing — chemical, mechanical, and bend.
How QML Serves This Industry
TMT rebar manufacturers must demonstrate compliance with IS 1786 for every production lot. QML provides the complete suite of IS 1786 acceptance tests — chemical analysis, tensile, yield, elongation, mass per metre, bend, and rebend — with test reports that are accepted by quality inspectors, project consultants, and NABL-aware certification bodies.
Testing Scope for TMT & Rebar Manufacturing
Every testing requirement matched to what QML does and the applicable standard.
| Testing Requirement | What We Do | Standard |
|---|---|---|
| Chemical composition compliance | OES analysis — C, Mn, Si, S, P, Cr, Ni, Cu, CEQ calculation per IS 1786 | IS 8811 / ASTM E415 |
| Tensile & yield strength | UTS, yield stress, 0.2% proof stress on full-section or machined specimens | IS 1608-1 / IS 1786 |
| Elongation (% EL) | Percentage elongation on gauge length per IS 1786 Table 3 limits | IS 1608-1 |
| Mass per metre | Weighing on calibrated balance — actual vs. nominal mass comparison | IS 1786 |
| Bend test | Cold bend over mandrel — no crack / split on outer surface | IS 1599 / IS 1786 |
| Rebend test | Bend, ageing at 100 °C, rebend — surface crack inspection | IS 1786 |
| Rib geometry & surface condition | Visual inspection and optical measurement of rib pattern per IS 1786 | IS 1786 |
