Test Method Statements
Reinforcement Steel Tensile & Bend Test
Testing rebar samples for yield strength, tensile strength, elongation and bend to confirm grade (e.g. Grade 60).
Reference standards: ASTM A370, ASTM A615 / A706
Equipment
- Universal testing machine (UTM)
- Extensometer
- Weighing scale
- Bend mandrel
Procedure
- Take samples (≥ 1 m long) from each diameter per heat or per 25–50 tons delivered, witnessed by the consultant.
- Weigh and measure length to check unit mass against nominal (D²/162 kg/m).
- Mark gauge length (200 mm) and grip the sample in the UTM.
- Load steadily; record yield load, ultimate load and final elongation.
- Bend a separate sample 180° around the specified mandrel and inspect for cracks.
Acceptance criteria
- Grade 60: yield ≥ 420 MPa, tensile ≥ 620 MPa.
- Elongation ≥ 7–9% depending on bar size.
- Unit mass within −6% of nominal; no cracks on the bent surface.
Health & safety
- Wear PPE: helmet, safety shoes, gloves and eye protection.
- Stand clear — bars can whip at fracture.
FAQs
What is the Reinforcement Steel Tensile & Bend Test used for?
Testing rebar samples for yield strength, tensile strength, elongation and bend to confirm grade (e.g. Grade 60).
Which standard does it follow?
It is based on ASTM A370, ASTM A615 / A706. Always follow your project specification where it differs.
Can I print or submit this?
Yes. Use Print / PDF, add your project details and submit it through your normal approval process. Get it reviewed by your engineer or consultant first.
Is it free?
Yes. The library is free to read and print, without an account.
