This standard specifies the requirements for a two component, cold curing, chromate-free epoxy or
polyurethane, high corrosion resistant primer which can be used with or without a finish for aerospace
applications.
The properties specified in this standard are obtained on defined aluminium alloy test pieces prepared in
accordance with EN 3837 and ISO 3270. The ability of the material to be used for a specific application (e.g.
alternative substrate, alternative primer, specific drying conditions etc.) shall be determined by supplementary
tests to confirm that the requirements of this standard are met.
