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.

21、s of this document, the following terms and definitions apply. 3.1 marking action of affixing one or more marks on a medium 3.2 mark physical information, composed of legible characters on the item or its packaging 3.3 permanent mark mark produced by means of a marking process whose characters can o
22、nly be eliminated by removing material (machining) 3.4 temporary mark mark produced by means of a marking process whose characters can be easily removed 3.5 character each of the elements which compose the mark: letter, figure, symbol, separator, etc. 3.6 design authority person or corporate body wh
23、o is in charge of the design definition 3.7 design definition creative activity which, starting from expressed needs, existing means, and technological possibilities, results in the design of a product meeting these needs and industrially feasible BS EN 4301:2009EN 4301:2009 (E) 5 3.8 manufacturer p

25、 out the provisions stated therein 3.10 production source person or corporate body who is responsible, with respect to the manufacturer, for manufacturing and inspecting a cast or forged, pre-machined, finished item or material. This may involve a subcontractor or an accessory manufacturer. To the e
26、xtend that he is given the order, he becomes a producer 3.11 subcontractor person or corporate body who carries out, on behalf of and under the responsibility of a supplier, all or part of the business venture, contract, or order concluded by the customer NOTE In the case of Public Contracts, a sing
27、le subcontractor is not allowed to execute the entire contract entered into by the customer. 4 Symbols and abbreviations O.C.R. Optical Character Recognition 5 Arrangement of marks 5.1 General Marks are to be made in the same order as that shown by the combinations for the standard arrangements (alp
28、habetical code) identified by numerical codes given in Table 2 or in accordance with a particular combination indicated in the note on the drawing. 5.2 General arrangement character height = h; minimum distance between two marks on the same line: 3 h; minimum distance between two successive lines: 1
29、,4 h; first character on all lines: aligned on the left; any marking placed to the right of the manufacturers identification number should be at a distance of at least 15 mm from it.
