How to decipher a Certificate of Analysis ( COA)/MTR report?

Deciphering a COA report may pose a challenge, especially for those not frequently engaged with such documents. Complicating matters, COA formats lack a standardized structure, and the documents are commonly translated from other languages, adding an extra layer of complexity. However, amidst these challenges, when navigating a Certificate of Analysis/Mill Test Report, it's reassuring to know that the verification of the material's physical and chemical composition remains a consistent aspect, irrespective of the document's origin.

Reading an COA/MTR/MTC – Step 1

The initial examination of an MTR commences with a physical assessment of the material either on the shop floor or within the warehouse. Verification involves confirming the presence and clear identification of the heat number on the material's surface. A comparison between this number and the corresponding MTR is conducted to ensure alignment. Basic surface and edge measurements are then performed to affirm that the material adheres to project specifications based on physical dimensions and thickness.

Reading an COA/MTR/MTC – Step 2

Moving to subsequent inspection steps, individuals need to consult the relevant ASME/ASTM/EN standards section corresponding to their project's material requirements. Here, the chemical composition table is located, and a comparison is made between the percentage values presented in the MTR and the acceptable range specified in the table. Common elements include Carbon (C), Chromium (Cr), Copper (Cu), Manganese (Mn), Molybdenum (Mo), Nitrogen (N), Nickel (Ni), Phosphor (P), Sulphur (S), and Silicon (Si).

Reading an COA/MTR/MTC – Step 3

Following the examination of the chemical analysis, attention is directed to the mechanical property table associated with the same specification. A parallel process is undertaken, comparing the measured values in the MTR with the acceptable range outlined in the mechanical properties section.
