1范围 ISO 13209的本部分规定了一种标准化的、独立于测试人员的、基于XML的数据交换格式，用于诊断测试序列的文档和正式描述。该格式用于支持在电子系统供应商、车辆制造商和服务经销商/维修车间之间传输诊断测试序列逻辑的要求。 ISO 13209的这一部分介绍了ISO 13209背后的基本原理。它概述了文档集和结构，以及用例定义和供所有后续部分使用的公共资源集（定义、参考）。

1 Scope This part of ISO 13209 specifies a standardized, tester-independent, XML-based data exchange format for the documentation and formal description of diagnostic test sequences. The format serves to support the requirements of transferring diagnostic-test-sequence logic between electronic system suppliers, vehicle manufacturers and service dealerships/repair shops. This part of ISO 13209 provides an introduction to the rationale behind ISO 13209. It gives an overview of the document set and structure along with the use case definitions and a common set of resources (definitions, references) for use by all subsequent parts.
