Material test report or Mill test report certifies that the chemical analysis and mechanical properties are in conformance with the specified specification. An MTR certifies a material’s compliance with the standard specification such as ASME Section II Part A and B or ASTM. Sep 28,  · A Mill Test Certificate (MTC), or Mill Test Report (MTR), is issued by a manufacturer to certify the chemical and mechanical features of a product and its compliance to the applicable norms and technical specifications. Typically, Mill Test Certificates conform to the EN standard and are related to steel products.


What is a Mill Test Report?


Material test report or Mill test report certifies that the chemical analysis and mechanical properties are in conformance with the specified specification. The MTR is supplied from the material manufacturer such as plate manufacturer, casting manufacturer, forging manufacturer, etc. When the steel plate is in its molten condition, a sample is drawn out from the batch for analysis of its chemical composition.

This plate is given a particular identification number known as heat number. The heat number provides a way to trace back the steel plates to its production units and process conditions. Several plates might have identical heat number, and this is normal since that indicates both plates made from the same batch of mill test report material.

Assume you have assigned for inspection of pressure vessel plate material at the pressure vessel manufacture shop. The vessel manufacturer provides you with MTR for purchased plate material from his supplier. Following Mill test report provided to you, mill test report. This is just for example; the MTR header has been removed. You will walk on the shop floor and make a visual inspection.

With this checking, you make sure your MTR is the one generated for this plate. Based on the project requirement, you might also run a visual inspection on plate edges, plate surface and also make dimensional inspection especially thickness measurement. Locate the chemical composition table and compare the percentage values in the MTR with the acceptance range in the table e.

Locate the mechanical property table in the same specification, mill test report. It generally comes after chemical composition table. Similarly, compare the measured value in the Mill test report with the acceptance range in the mechanical properties table.

For this example, you need to check yield strength, tensile strength, elongation, mill test report, reduction in area and hardness. If the result of all verification on all these 3 steps were satisfactory, then the result of MTR review will be satisfactory.

When you review the project specification even the inspection and test plan occasionally you might see that project requires the material test report being provided either in conformance with EN 3, mill test report. The material certificate is provided and certified by the material manufacturer. Besides, material manufacturer an independent inspection agency also shall authenticate the MTR.

You typically need to see two stamps and signatures, one from the material manufacturer and the second one from inspection agency. The inspection agencies usually assign an inspector to witness the chemical composition analysis test and mechanical testing. The third party inspector verifies test result with acceptance criteria and also checks heat numbers and test specimens. If all items met the requirements, the inspector would sign off the MTR.

mill test report

 

Material test report or Mill test report certifies that the chemical analysis and mechanical properties are in conformance with the specified specification. An MTR certifies a material’s compliance with the standard specification such as ASME Section II Part A and B or ASTM. The Certified Mill Test Report is a tool used to ensure that received raw material matches the engineering and purchase order requirements. A Certified Mill Test Report (CMTR) is a quality assurance document generated by the raw material manufacturer and provided with the material to intermediate suppliers and ultimately to a finished goods.
