ASD-STAN prEN 9208属于与项目管理规范相关的EN 9200文件。本文件的目的如下:明确/提醒（需求）技术规范（N）TS的概念；定义制定、批准、使用和更新a（N）TS的原则和条件；提出一个（N）TS模板。该模板确定了（N）TS中涉及的主题和相关要求的类型，而不是完全详尽或强制性的。它应该像检查表一样进行分析，并根据感兴趣产品的类型、涉及机构的背景和合同细节进行定制。制定a（N）TS的原则既适用于有形产品，也适用于无形产品（e。 g、 服务）。这些原则处理的客户/供应商关系也可能适用于单个组织。本文件讨论了客户和供应商的概念，不区分内部关系和外部关系。本文件实施并适应EN 16271标准，以满足航空领域的具体需求，以及更广泛地满足其他领域的需求。本文件更明确地阐述了ISO/IEC/IEEE 29148文件中专门用于需求工程的某些方面，例如在合同基础上制定a（N）TS的责任，以及在计划内制定a（N）TS的过程（阶段和里程碑）。 它还补充了ISO/IEC/IEEE 29148提出的技术规范框架，尤其是与操作安全和结果保证相关的要求。附录A中给出了功能性能规范（FPS）和（N）TS之间存在的需求表达关系。

ASD-STAN prEN 9208 belongs to the documents going along with the EN 9200 relating to Project Management Specification.The aims of this document are as follows:to specify/remind the concept of (Need) Technical Specification (N)TS;to define the principles and conditions for drawing up, approving, using and updating a (N)TS;to propose a template of (N)TS.The template identifies topics and types of related requirements to be covered in a (N)TS without being completely exhaustive or mandatory. It should be analysed like a check-list and tailored according to the type of the product of interest, the context of the bodies involved and the contractual details.The principle of drawing up a (N)TS applies to both tangible and intangible products (e.g. services).The customer/supplier relationship addressed by these principles may also apply within a single organisation. The concepts of customer and supplier are discussed in this document without distinction between internal or external relationship.This document implements and adapts to the context the EN 16271 standard, in order to meet the specific needs of the aeronautical field and more generally the needs of other fields.This document is more explicit about certain aspects of the ISO/IEC/IEEE 29148 document dedicated to requirements engineering, such as the responsibility for drawing up a (N)TS on a contractual basis and also the process of drawing it up within a programme (stages and milestones). It also supplements the technical specification framework proposed by ISO/IEC/IEEE 29148, in particular with requirements relating to safety of operation and result assurance.The relationships existing between Functional Performance Specification (FPS) and (N)TS for expression of needs are given in Annex A.
