16、Scope and field of application This standard defines the characteristics of radial mounting retaining rings, in steel, phosphated, for aerospace applications. These retaining rings are used only when EN 3384 cannot be used for installation problems. The phosphating restricts the use at temperatures
17、not exceeding 200 C. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document
