Which of the following is NOT typically included on supplier Material Certifications?

• A. Manufacturer, material type, lot/batch numbers, compliance with specs, test results, date, and authorized signature.
• B. Supplier contact name and phone number.
• C. Date, and authorized signature.
• D. Lot/batch numbers and test results.

Answer: (B)

Material Certifications focus on proving material identity, compliance with specs, and traceability. A valid cert should identify who produced the material, what the material is, the corresponding lot or batch, indicate compliance with the required specifications, include relevant test results, show the date, and bear an authorized signature. These elements allow you to trace the material back to its source and verify it meets quality requirements. A supplier contact name and phone number is not typically part of the certification content itself; it’s more of a procurement or vendor-record detail, not essential for verifying material quality. Therefore, the contact information is the item not typically included on supplier Material Certifications.
