EN 2434-002:2010 (E) 4 Introduction This European Standard is part of a series of EN non-metallic materials standards for aerospace applications. The general organisation of this series is described in EN 4385. This European Standard is a level 3 document as defined in EN 4385. Definition of subcase numbering in Table 2 to Table 5 is given in EN 7000-9. 1 Scope This European Standard specifies the requirements for a two component polyurethane finish to be applied over a primer for interior and exterior aerospace applications, where maximum resistance to normal operational fluids is required. The properties specified in this European Standard are obtained on defined aluminium alloy test pieces prepared in accordance with EN 3837 Procedure A and EN 23270 and painted with primer to EN 2435-002. 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. 2 Normative references The following referenced documents are indispensable for the application of this document.
