8、ications. The properties specified in this standard are obtained on defined aluminium alloy test pieces prepared in accordance with EN 3837 Procedure A and IS0 3270 and painted with primer to prEN 2435-02. The ability of the material to be used for a specific application (e.g. alternative substrate,
