This standard specifies the basic requirements for a two component, cold curing, chromate-free epoxy or
polyurethane, 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, process A 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.
