15+ Test TypesTensile, hardness, impact, bend, torque, and corrosion — complete mechanical characterisation of metallic materials on calibrated, traceable equipment.
Tensile & Deformation Tests
Tensile Strength
IS 1608 / ASTM E8
Maximum load per unit area before fracture. Primary structural property.
Yield Strength
IS 1608 / ASTM E8
Elastic limit of the material; onset of permanent deformation.
0.2% Proof Stress
IS 1608
Stress at 0.2% plastic offset — standard yield for non-ferrous and austenitic alloys.
0.5% Proof Stress
IS 1608
Stress at 0.5% total extension under load.
1% Proof Stress
IS 1608
Stress at 1% total extension — specified in some IS standards.
Elongation
IS 1608 / ASTM E8
Percentage increase in gauge length at fracture — ductility measure.
Bend Test
IS 1599 / ASTM E290
Ductility and surface integrity when bent over a mandrel to specified radius.
Rebend Test (TMT Bar)
