EN 2436-002:20064 0 Introduction This standard is part of a series of EN non-metallic materials standards for aerospace applications. The general organ
20、isation of this series is described 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 requirements for a two component, cold curing, chromate-free epoxy or polyurethane, h
21、igh corrosion resistant primer 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 and ISO 3270. The ability of the material to be used for a specific
22、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
