A Material Test Report (MTR), also known as a Mill Test Report (MTR), Certified Mill Test Report (CMTR), or Certificate of Test, is a quality assurance document commonly used in the metals industry. It certifies that a material, typically made of metal such as steel, aluminum, brass, or other alloys, meets the required physical and chemical properties and complies with relevant standards set by international organizations like ANSI, ASME, or ASTM. The MTR serves as proof that a material adheres to specific quality and performance standards, ensuring its suitability for critical applications.
