EN 9300 is split into different separate standard parts to make the standard applicable for different business requirements and extendable for
14、 further long term archiving formats. Structure and content of EN 9300 standard parts are detailed in this document. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated ref
15、erences, the latest edition of the referenced document (including any amendments) applies.

16、ard, the terms, definitions and abbreviations given in EN 9300-007 apply. 4 Applicability 4.1 General EN 9300 is a standard for long term archiving and retrieval of digital technical product documentation. Since technical product documentation, such as design documents, are generated, exchanged and
17、used digitally, architecture, technology, processes, data formats, rules and regulations need to be adapted to enable digital retention and long term archiving. EN 9300 closes this gap as the European standard for digital long term archiving. Long Term means long enough to be concerned with impacts
18、of changing technologies, including support for new media and data formats, or with a changing user community. The terms retention and long term archiving are explained in EN 9300-003. Different legal, certification, business and process requirements influence retention and archiving. The main requi
19、rements are explained in EN 9300-002. EN 9300 considers two main requirements aspects. Legal and certification aspects Technical aspects All its concerned parts (see clause 5). prEN 9300-001:20055 4.2 Legal and certification aspects Laws, their applicability and their interpretation vary from countr
20、y to country, and are most likely to change over the period of time when this standard is in use. EN 9300 considers requirements coming from legal and certification rules and regulations on long term archiving of technical documentation. The standard defines architecture, processes and data formats
21、to fulfil these requirements. It does not provide means for the proof of digital technical documentation in cases of action on law or for certification. Different legal and certification rules exist worldwide and they have been not completely harmonized in Europe. There are still different rules of
22、various airworthiness authorities. Some examples for rules and regulations are given on example by the German and European law. Product Liability Law: According to the German product liability law, from 1990-01-01 the manufacturer of defective products is bounded to pay compensation in the case that
23、 somebody was killed, suffered or something was damaged by use of this product. This case is represented through an absolute liability. Normally the aggrieved party has to prove the cause of failure and detriment, but it may happen that the manufacturer has to provide evidence which proves that the
24、product was developed and manufactured according the standards, norms and knowledge valid at that times. The ability to claim compensation expires 10 years after the product rollout. Product liability according “823 BGB”: Everybody who injures somebodys health, body, freedom, possession is bounded t
25、o pay compensation. This case involves the placing on the market of defective products by a manufacturer. The manufacturer has to prove the absence of defects and the correctness of the product. The claim for compensation expires 30 years after the damaging event. European Union Directive 99/93/EG:
26、The directive 99/93/EG became effective on the 19thof January 2000. The directive defaults had to be realized within national guidelines by July 19th2001. Throughout the directive a common and comparable pan-European standard for offering and using signature proceedings shall be established. The dir
27、ective rules the legal frameworks and third party certification, intended for the smooth functioning of the single European market. The main difference to the until then existing German signature law is the introduction of a sophisticated signature as well as a qualified certificate. If both are pre
28、sent within an electronic business case, the electronic signature must be put on par with the hand written signature and more important, the electronic signature must admitted into evidence in case of a lawsuit. (Art. 5, 99/93/EG) European Union Directive 98/37/EC: The Machinery Directive1came into
29、force on January 1st, 1993 and has become mandatory since January 1st, 1995. This means that from that date, no machine can be placed on the EU single market or installed if it does not bear the CE Marking. Before drawing up the CE declaration of conformity, the manufacturer, or his authorised repre
30、sentative in the Community, shall have ensured and be able to guarantee that the documentation listed below is and will remain available on his premises for any inspection purposes: a) technical construction file b) for series manufacture, the internal measures that will be implemented to ensure tha
31、t the machinery remains in conformity with the provisions of the Directive. The manufacturer must carry out necessary research or tests on components, fittings or the completed machine to determine whether by its design or construction, the machine is capable of being erected and put into service sa
32、fely. The technical documentation must be stored for at least 10 years after the fabrication of the last unit of the product Patent law: To avoid unwarranted demands based on royalties a manufacturer has to provide evidence that he has not infringed a patent. A demand for violating of copyrights can
33、 be notified retrospective for 30 years. Additional to the general legal demands, there are aerospace industry established standards, company specific rules and recommendations regarding documentation and archiving of digital documents. prEN 9300-001:20056 The duration of retention differs for the d
34、ifferent types of documents. For CAD and PDM data there are differences for Design and Type Design Data. Regarding JAA-Recommendations (JAR 21.55, JAR 21.105) the type design data have to be retained three years after the “product type certificate has been completely withdrawn or as agreed with the
35、relevant authority”2. In the aerospace industry this can lead to archiving durations more than 70 years. In general it can be said, that keeping of documents for the future have to take place in such a way that they are usable mainly for the proof of: Legal and certification constraints Contractual
36、constraints Re-use of data belonging information Manufacturing processes Modifications on products and documents EN 9300-01x, EN 9300-1xx and EN 9300-2xx define in more detail auditable processes, data definitions and formats for long term archiving for supporting legal and certification requirement
37、s. 4.3 Technical aspects Long term archiving of CAD data has meant so far archiving of 2D drawings as paper drawings, digital images (e.g. as TIFF), paper or aperture card documents. Because of the continuous development of technical product documentation EN 9300 has to consider the changes of metho
38、ds and tools, which are used for design, manufacturing, customer support and archiving. The history of changes for each method is categorized and listed within four main categories: before 1980: Mainly manual paper drawings and a minor number of 2D CAD drawings; between 1980-1995: Mainly 2D CAD draw
39、ings, a minor number of manual paper drawings and additionally 3D surface CAD design; The usage of 3D solid Afterwards the usage of 3D solid & assemblies with extended GD&T design information might be implemented. The following figure shows that an integration of 3D Technologies and GD&T will become
40、 an important topic along the complete product documentation lifecycle of design, manufacturing, customer support and long term archiving. 1970 1975 1980 1985 1990 1995 2000 2005 2010 ffDesign(Methods & tools)2Dpaper3DSurf.+2D2D+3DSOL.GD&TManufacturing(Methods & tools)Customer Support 2DLTA Technolo

46、shape of a product, DMU and manufacturing. 2D drawings are generated directly from 3D models and are no longer fully dimensioned. All necessary views are available within the 3D model. Therefore at least a combination of product structure, 3D and 2D information together is needed to describe a produ
47、ct completely. The current situation is characterized by a large number of 3D geometric models, which are kept write-protected in databases in their native formats. With the continuing change of CAD technology, this data should be checked and migrated regularly in order to conserve the required geom
48、etric model quality. The native formats of CAD and PDM systems change frequently compared with the legal requirements for archiving periods due to technical developments in the products or to changes in the hardware and operating systems. After each migration the native formatted data shall be check
49、ed for consistency and completeness. There is no guarantee that the data has not changed after the first release process. A conversion of the native product data into a more stable format is essential. EN 9300 does not require regular migration of data, but it provides processes, formats and rules to guarantee data quality and content in order to support legal, certification and business requirements. The data quality and conversion of data into a neutral, standardized archive format are the basis for this standard. EN 9300 def
