ASD-STAN PREN 4476 PDF

This European Standard specifies the requirements for an intermediate coat to be applied over a primer for aerospace applications and with a topcoat for aerospace applications on top.

The properties specified in this standard are obtained on defined aluminium alloy test pieces prepared in accordance with EN 3837 and EN ISO 3270 and painted with primer listed in Table 1. Topcoat listed in Table 1 is to be applied on intermediate coat to this standard. The ability of the material to be used for a specific application (e.g. alternative substrate, alternative primer, specific drying conditions, etc.) should be determined by supplementary tests to confirm that the requirements of this standard are met.
