IEC GUIDE 127:2026

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'. (See ISO/IEC Directives, IEC Supplement:2021, A.1.1.)
