EN 2436-001:20064 0 Introduction This standard is part of a series of EN non-metallic materials standards for aerospace applications. The general organisation of this series is descri
20、bed in EN 4385. This standard is a level 3 document as defined in EN 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, corrosion resistant primer
21、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 ac-cordance with EN 3837, process A and ISO 3270. The ability of the material to be used for a specific applica-tion (e.g.
22、alternative substrate, alternative primer, specific drying conditions etc.) shall be determined by sup-plementary 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.
