This standard BS EN 2435-004:2006 Aerospace series. Paints and varnishes. Corrosion resistant chromated two component cold curing primer is classified in these ICS categories:

• 49.040 Coatings and related processes used in aerospace industry

This standard defines the requirements for a two component, chromated epoxy or polyurethane, high corrosion resistant primer with a high degree of resistance to aggressive hydraulic fluids and improved tolerance to the standard of surface preparation 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 or B or C or D 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.
