标准摘要
[中文适用范围]： 本文件描述了如何通过ISO 16739-1（工业基础类，IFC）和EN 17549-2标准，由建筑服务产品制造商向建筑服务系统设计者交换产品目录数据。本文件规定了如何使用数据字典中存储的定义来建立产品目录的结构和内容。本文件的适用范围包括：——产品目录的提供和交换流程；——产品的几何表示规则；——使用IFC表示产品、产品类别、端口、进出口、组件和附件；——在IFC中表示属性，并使用IFC约束表示产品变体；——参数化几何的表示以及为选定变体生成IFC几何；——文章编号的计算。生成的产品目录可用于设计人员选择所需产品，并将其集成到建筑服务系统的模型中。本文件的目标读者包括建筑环境领域的软件提供商，以及在该领域内创建或通过软件工具使用产品目录的专业人士。本文件不涉及数据字典中属性的表示，数据字典的使用方法在ISO 16757-4中进行了描述。 [外文原描述]： This document describes how product catalogue data for building services products is exchanged by means of ISO 16739-1 (Industry Foundation Classes, IFC) and EN 17549-2 from manufacturers to designers of building services systems. This document specifies how the product catalogue structures and content are set up using the definitions stored in a data dictionary. In scope of this document are: — processes for the provision and exchange of product catalogues; — rules for the geometrical representation of products; — representation of products, product classes, ports, in/outlets, components and accessories by using IFC; — representation of properties in IFC and the use of IFC constraints for the representation of product variants; — representation of parametric geometry and the generation of IFC geometries for selected variants; — calculation of article number. The resulting product catalogue can be used by designers to select the desired products and integrate them into their model of the building services system. The expected audience of this document are software providers for the built environment sector and professionals working in the sector who create product catalogues or use product catalogues by means of software tools. Not in scope of this document is the representation of properties in data dictionaries. The use of data dictionaries is described in ISO 16757-4.
