This standard specifies the minimum requirements for a two-component, chromated 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, procedure A and ISO 3270. The ability of the material to be used for a specific
application (e.g. alternative substrate, specific drying conditions, etc.) shall be determined by supplementary
tests to confirm that the requirements of this standard are met.
