EN 2535:2011 (E) 5 1 Scope This European Standard defines the method for depositing cadmium layers according to the vacuum deposition process, for use in aerospace construction. According to this process, cadmium metal is vaporised under vacuum and deposited directly on the base material with an interlayer. The coating produced in this way is ductile and electrically conductive. This standard should be applicable whenever referenced. 2 Normative references The following referenced documents are indispensable for the application of this document.
