What information should a rebar material test report include?

• A. Bar size, grade, manufacturer, lot number.
• B. Coating status and test results.
• C. Bar size, grade, manufacturer, lot number, coating status, and test results.
• D. Delivery date and color of coating.

Answer: (C)

A rebar material test report must provide complete identity, traceability, and performance data for each batch. The most complete report lists bar size, grade, manufacturer, lot number, coating status, and test results. Bar size and grade identify the exact reinforcement used and its mechanical properties, which are essential for matching the material to the design requirements. Manufacturer and lot number establish traceability to a specific production run, so any issues can be traced back and linked to the corresponding test data. Coating status matters for epoxy-coated or other coated bars because the coating affects corrosion protection and bonding behavior, and inspectors need to verify it is present and in acceptable condition. Test results give the actual measured properties the material achieved, confirming it meets the applicable specs and project requirements (such as strength, ductility, and any coating quality criteria). Without all of these elements, you can’t reliably verify compliance or trace material back to its quality records. The combination of identity, traceability, coating information, and test data provides a complete picture for quality control and compliance.
