Which document is signed by an authorized official of a laboratory and shows that a material, product, or system has been tested in accordance with specified requirements, and must have been completed within 3 years of the date of contract award?

• A. Samples
• B. Test Reports
• C. Certificates
• D. Manufacturer's Field Reports

Answer: (B)

A test report is the formal laboratory document that proves testing was performed to the contract’s specified requirements and is signed by an authorized official of the laboratory. It provides the actual test data, methods, equipment, and conditions, and confirms that the material, product, or system meets the contract specs. The requirement that it be completed within three years of the contract award ensures the testing reflects current standards and project needs. This makes it the best choice because it is an independent, lab-issued record of verified testing, not just a sample, a certification, or a manufacturer-produced field note. Samples are simply the material itself; certificates may attest to conformity but often lack the complete test data and lab endorsement; manufacturer’s field reports come from the producer and may not be an independent verification against contract requirements.
