ISO 29845:2011建立并定义了各种复杂程度的产品、设备和装置规范文件中所需的文件类型。它涉及所有工程领域中从概念阶段到成品所使用的各种文档类型。 ISO 29845:2011的目的是促进（数据建模）产品数据管理系统的结构，促进文件的搜索和检索，建立文件类型，以便参与文件交换的各方更好地沟通和理解，并满足ISO 7200:2004中关于文件类型字段的要求。

ISO 29845:2011 establishes and defines the types of documents required to be in the documentation for the specification of products, equipment and plants at all levels of complexity. It deals with the range of document types used from the conceptual phase to finished product, in all engineering fields. The purpose of ISO 29845:2011 is to facilitate a structure for (data modelling) product data management systems, to facilitate searching and retrieval of documents, to establish document types for the purpose of better communication and understanding between parties involved in document interchange, and to fulfil the requirement in ISO 7200:2004 regarding document type fields.
