20、, Sweden, Switzer-land and the United Kingdom. EN 2436-004:20064 0 Introduction This standard is part of a series of EN non-metallic materials standards for aerospace applications. The gen-eral organisation of this series is described in EN 4385. This standard is a level 3 document as defined in EN

21、4385. Definition of subcase numbering in Tables 2 to 5 is given in TR 7000-9. 1 Scope This standard specifies the basic requirements for a two component, cold curing, chromate-free epoxy or polyurethane, high corrosion and fluid resistant primer with improved tolerance to the standard of surface pre

22、paration 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 D and ISO 3270. The ability of the material to be used for a specific application

23、 (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.
