Official basis (Method): ISO 105-A02 evaluates colour change; ISO 105-A03:2019 evaluates staining of adjacent fabrics. These are assessment scales, not laboratory stains.
Procurement note: Keep colour change and transfer/staining endpoints separate. Purchase the scale and exposure consumables required by the exact ISO105 test part.
