21、T+00:00 2006, Uncontrolled Copy, (c) BSI 4 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 4385. Definition of s
22、ubcase 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 which can be used with or without a finish for aerospace applications. The properties spec
23、ified 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 (e.g. alternative substrate, alternative primer, specific drying conditions etc.) shall be determi
24、ned 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. For dated refer- ences, only the edition cited applies. For undated references, the latest edition o
