21、rials standards for aerospace applications. The general organisation 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 basic requirements for a
22、 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 specified in this standard are obtained on defined aluminium alloy test pieces prepared in ac- cordance with EN 3837, pro
23、cess A and ISO 3270. The ability of the material to be used for a specific applica- tion (e.g. 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 Th
