18、coding system for marks, the processes used to produce these marks, as well as the general marking requirements for the identification of aerospace engine items. This document is applicable to items whose engineering drawing or design folder refers to EN 4301 for all issues that are not in contradic

19、tion with specific indications appearing on the engineering drawing or in the design folder. This document is not applicable to items requiring an identification plate. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated referen

20、ces, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
