I write the alloy lot’s ISO class (ISO 22674) right on the work ticket before casting; it’s kept me from grabbing a batch labeled “Type 4” that didn’t meet the flex spec, and if the CoA’s vague I call the supplier to confirm. Anyone else run into this mismatch?

, those end-of-day remakes: I taped a tiny ISO 22674 cheat card to the burnout oven and only pour from a scrap bin tagged ‘Type 4’ + lot#, with a QR to the alloy’s datasheet — it’s stopped me from grabbing a ‘Type 4’ that wasn’t compliant. Small caveat: some suppliers say Type 4 without listing ISO 22674:2016 on the COA, so I verify the proof strength on their sheet or this summary page: https://www.iso.org/standard/73016.html.
