22、ndard was prepared jointly by AIA, ASDSTAN, PDES Inc and the PROSTEP iViP Association.The PROSTEP iViP Association is an international non-profit association in Europe. For establishing leadership in ITbased engineering it offers a moderated platform to its nearly 200 members from leading industries
23、, system vendors and research institutions. Its product and process data standardization activities at European and worldwide levels are well known and accepted. The PROSTEP iViP Association sees this standard and the related parts as a milestone of product data technology.PDES Inc is an internation
24、al non-profit association in USA. The mission of PDES Inc is to accelerate the development and implementation of ISO 10303, enabling enterprise integration and PLM interoperability for member companies. PDES Inc gathers members from leading manufacturers, national government agencies, PLM vendors an
25、d research organizations. PDES Inc. supports this standard as an industry resource to sustain the interoperability of digital product information, ensuring and maintaining authentic longevity throughout their product lifecycle.Readers of this standard should note that all standards undergo periodic
26、revisions and that any reference made herein to any other standard implies its latest edition, unless otherwise stated.The Standards will be published under two different standards organizations using different prefixes. ASD Stan will publish the standard under the number EN 9300xxx. AIA will publis

36、t, and all the assembly structure data are contained in the same Submission Information Package (SIP). The assembly may be contained in one file or in a set of files (see Figure 3: archiving overview of the submission information package).5BS EN 9300115:2018EN 9300115:2018 (E)Figure 3 Archiving over
37、view of the submission information package5.1.2 UC2: Bottom up and incremental archivingThe assembly structure is archived subset by subset. The assembly structure files are submitted in different submission information packages. For example, in bottomup archiving, the assembly structure files are s
38、ubmitted from the lower level up to the top level (see Figure 4).Figure 4 Bottom up archiving of the assembly structure6 Essential information for explicit CAD assembly structureThe following list describes the essential information for a CAD assembly structure. The essential information are capture
39、d, verified and validated through the core model and the rules. The core model is described in the Clause 7 “Definition of Core Model for an explicit CAD assembly structure” and the rules are described in the Clause 8 “Verification rules of CAD explicit assembly structure” and Clause 9 “Validation r
