Where you'll meet this in procurement
You will meet IS 3589 when a buyer, consultant, or mill quote names a governing specification. Confirm which revision applies, what tests the standard requires, and whether the grade on the MTC actually matches the IS 3589 call-out on the RFQ before you lock commercial terms.
