Aerospace series. Laser surface marking by discoloration Ingestion-build-117251 Forced convection unit air coolers1 Scope This European Standard specifies the marking rules for aerospace products, semi finished products, and ready to use parts, which need surface marking by discoloration using a laser source to identify the part and or enhance its traceability. This type of marking can be used on a wide range of materials (both metallic and non metallic) and coatings (paints, varnishes). It is in line with the part definition.
