Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identif
24、ying any or all such patent rights. This document supersedes EN 9132:2006.

BS E
26、N 9132:2017EN 9132:2017 (E) 5 Rationale This standard has been revised to clean up the general text/content and to reformat the document to the latest format/style guide. This standard was created to provide for uniform quality and technical requirements relative to metallic parts marking performed
27、within the aviation, space, and defence industry. This standard can be invoked as a stand-alone requirement or used in conjunction with EN 9100-series standards (i. e., EN 9100, EN 9110, EN 9120). Foreword To assure customer satisfaction, the aviation, space, and defence industry organizations must
28、produce and continually improve safe, reliable products that meet or exceed customer and regulatory authority requirements. The globalization of the industry, and the resulting diversity of regional/national requirements and expectations, has complicated this objective. End-product organizations fac
29、e the challenge of assuring the quality of, and integrating, product purchased from suppliers throughout the world and at all levels within the supply chain. Furthermore, suppliers and processors, within the industry, face the challenge of delivering product to multiple customers having varying qual
30、ity expectations and requirements. The aviation, space, and defence industry established the International Aerospace Quality Group (IAQG) for the purpose of achieving significant improvements in quality and safety, and reductions in cost, throughout the value stream. This organization includes repre
31、sentation from companies in the Americas, Asia/Pacific, and Europe. This document standardizes data matrix quality requirements for parts marking for the industry. The establishment of common requirements, for use at all levels of the supply-chain by organizations, should result in improved quality
32、and safety, and decreased costs, due to the elimination or reduction of organization-unique requirements and the resultant variation inherent in these multiple expectations. BS EN 9132:2017EN 9132:2017 (E) 6 1 Scope This standard defines uniform quality and technical requirements relative to metalli
33、c parts marking performed using “data matrix symbology” within the aviation, space, and defence industry. ISO/IEC 16022 specifies general requirements (e. g., data character encodation, error correction rules, decoding algorithm). In addition to ISO/IEC 16022 specification, part identification with
34、such symbology is subject to the requirements in this standard to ensure electronic reading of the symbol. The marking processes covered by this standard are as follows: Dot Peening; Laser; Electro-Chemical Etching. Further marking processes will be included, if required. Unless specified otherwise
35、in the contractual business relationship, the company responsible for the design of the part shall determine the location of the data matrix marking. Symbol position should allow optimum illumination from all sides for readability. This standard does not specify information to be encoded. 1.1 Conven
36、tion The following conventions are used in this standard: The word “shall” indicates mandatory requirements; The word “should” indicates requirements with some flexibility allowed in compliance methodology. Producers choosing other approaches to satisfy a “should” shall be able to show that their ap
37、proach meets the intent of the standards requirement; The words “typical”, “example”, “for reference” or “e. g.” indicate suggestions given for guidance only; Appendices to this document are for information only and are provided for use as guidelines; Dimensions used in this document are as follows.

41、angular within ECC 200 requirements (see ISO/IEC 16022). Square is preferred for easier reading. c) Quiet zone: The quiet zone (margin) around the matrix shall be equal to or greater than one module size. d) Round surface: If the marking is made on a round/curved surface, the symbol coverage shall b
42、e equal to or less than 16 % of the diameter or 5 % of circumference. e) Symbol size: To facilitate electronic reading of the symbol, the overall symbol size should be less than 25,4 mm (1 000 inch), outside dimension, longest side. Irrespective of matrix size used, the requirements included in this
43、 standard shall be applied. f) Angular distortion of the symbol: Angular deviation of 90-degree axes between row and column shall not exceed 7 degrees (see Figure 1). Key 1 Angle of Distortion Figure 1 Angle of distortion 3.2 Dot peening 3.2.1 Description of process a) Dot-peen marking technology ty
44、pically produces round indentations on a parts surface with a pneumatically or electromechanically driven pin, otherwise known as a stylus. Critical to the readability of dot-peen marked symbols are the indented dots shape, size, and spacing. The dot size and appearance are determined mostly by the
45、stylus cone angle, marking force, and material hardness. The BS EN 9132:2017EN 9132:2017 (E) 8 indented dot created should be suitable to trap or reflect light and large enough to be distinguishable from the parts surface roughness. It should also have spacing wide enough to accommodate varying modu
46、le sizes, placement, and illumination (see Figure 2). Determine minimum module size according to the surface texture. See Table 1, Figure 3 (inch), or Figure 4 (mm). Calculate dot size with regard to the above minimum module size in choosing stylus angle (i. e., 60, 90, or 120) depending on maximum
47、depth allowed by engineering design requirements (see Table 2 for the optimum dot size). Determine matrix size depending on the information coded in the matrix (reference tables presented in Appendix A for minimum matrix size based on available marking area) Set up machine (e. g., height, air pressu
48、re, force) for desired dot geometry) Figure 2 Instructions for determination of marking parameters b) The issues involved in marking and reading dot-peen-marked symbols on metals are different than symbols printed on paper. The first fundamental difference is that the contrast between dark and light
49、 fields is created by artificial illumination of the symbol. Therefore, the modules shape, size, spacing, and part surface finish can all affect symbol readability. c) The key to a successful dot-peen marking and reading project is to control the variables affecting the consistency of the process. Symbol reading verification systems can provide feedback of the process parameters to some extent. Marking system operating and maintenance procedures shall be establis
