Downloaded from https://www.everyspec.com MIL-STD-31000B component produced in accordance with this data will be essentially identical to the original item or component. 3.1.19 Fully annotated model. A 3D CAD dataset, in which all necessary features to fully define the item (i.e. full design disclosure to include dimensions, tolerances, materials, notes, surface finishes, etc.) are included in a readily viewable form. (See ASME Y14.41) 3.1.20 Limited design disclosure model. A 3D CAD dataset sufficiently defined to provide a visual understanding of the item, but which does not contain full design disclosure.
Generally external interface characteristics and features such as weight and center of gravity will be sufficiently defined for the intended purpose. Sometimes referred to as an envelope model, shrink-wrap model or cosmetic model. 3.1.21 Metadata. Data that provides information about other data. For the purpose of this standard, metadata is defined to be data about a design and/or engineering design documents. (Part number, drawing number, nomenclature, revision, date approved, approved by, used on, etc., are examples of metadata). Metadata is used by the design and procuring activities to store, manage, and provide access to TDP elements. 3.1.22 Model Based Definition (MBD).
The practice of using 3D datasets containing the exact solid representation, associated 3D geometry and 3D annotations of a product’s dimensions, tolerances, materials, finishes and other notes to specify a complete product definition. (See ASME Y14.41) 3.1.23 Non-Government standardization document (a.k.a. Industry Standards). A standardization document developed by a private sector association, organization or technical society which plans, develops, establishes or coordinates standards, specifications, handbooks or related documents. These documents are available for purchase or free of charge to the general public.
Company standards are not considered as non-Government standardization documents. 3.1.24 Performance specification. A specification that states requirements in terms of the required results with criteria for verifying compliance, but without stating the methods for achieving the required results. A performance specification defines the functional requirements for the item, the environment in which it must operate, and interface and interchangeability characteristics. (MIL-STD-961) 3.1.25 Procuring activity.
The Government or private organization which establishes the requirements for an end item, service or set of data, and is responsible for the issuance of a contract or solicitation for these goods or services. 3.1.26 Product Lifecycle Management (PLM). The process or system used for managing product- related design, production and maintenance information. PLM systems are typically software applications designed for the purpose of lifecycle management of a product. 3.1.27 Quality Assurance Provisions (QAP). Documented requirements, procedures and criteria necessary for demonstrating that products conform to design requirements. 3.1.28 Reference documents.
Documents referred to in a TDP element, which contain information necessary to meet the information content requirements of that TDP element. 3.1.29 Software specification. A type of program-unique specification that describes the requirements and verification of requirements for the automatic acquisition, storage, manipulation, 7
