协作安全系统安全相关风险评估与降低指南

[中文适用范围]： IEC指南127:2026提供了关于编写标准的建议，旨在将安全因素纳入其中，以应对人类、机器和操作环境之间的相互关联，从而通过在标准中提供保护措施来降低风险。该文件补充了ISO/IEC指南51和IEC指南116，指定了与协作安全相关方面有关的额外建议。该文件特别补充了安全防护和辅助保护措施（第2步），并可能包括用户采取的保护措施（例如提供和使用额外的防护装置），如IEC指南116:2018图5所示。该文件不适用于与医疗器械相关的出版物的编写，这由ISO/IEC指南63[1]涵盖。注1：IEC指南116包括了可能对人类造成伤害的网络攻击的安全影响。注2：IEC标准化管理委员会（SMB）决定，此类指南可以包含强制性要求，所有开展属于指南范围内的技术工作的IEC委员会都必须遵循这些要求，同时也可以包含建议性内容，这些内容可能遵循也可能不遵循。本指南中的强制性要求通过使用“shall”来标识。仅用于建议的陈述则通过使用动词“should”来标识。（参见ISO/IEC指南，IEC补充：2021，A.1.1。） [外文原描述]： IEC GUIDE 127:2026 provides recommendations on drafting standards so as to include safety aspects where humans, machines, and the operational context mutually associate to mitigate risk by providing protective measures in standards. This document supplements ISO/IEC Guide 51 and IEC Guide 116 by specifying additional recommendations relevant to collaborative safety-related aspects in standards. This document supplements, in particular, the safeguarding and complementary protective measures (Step 2) and can include protective measures taken by the user (e.g. provision and use of additional safeguards), both illustrated in IEC Guide 116:2018, Figure 5. This document is not applicable for the development of publications related to medical devices, which is covered by ISO/IEC Guide 63 [1]. NOTE 1 The safety implications of a cybersecurity attack that has potential to cause harm to humans are included in IEC Guide 116. NOTE 2 The IEC Standardization Management Board (SMB) has decided that Guides such as this one can have mandatory requirements which shall be followed by all IEC committees developing technical work that falls within the scope of the Guide, as well as guidance which may or may not be followed. The mandatory requirements in this Guide are identified by the use of "shall". Statements that are only for guidance are identified by using the verb "should".
