Purpose: To identify the purpose and applicability of this document and the exclusions from the scope.<\/p>\n

Rationale: The scope excludes requirements for functional safety. Functional safety is addressed in IEC 61508-1. Because the scope includes computers that may control safety systems, functional safety requirements would necessarily include requirements for computer processes and software.<\/p>\n

The requirements provided in IEC 60950-23 could be modified and added to IEC 62368 as another \u2013X document. However, because of the hazardbased nature of IEC 62368-1, the requirements from IEC 60950-23 have been incorporated into the body of IEC 62368-1 and made more generic.<\/p>\n

The intent of the addition of the IEC 60950-23 requirements is to maintain the overall intent of the technical requirements from IEC 60950-23, incorporate them into IEC 62368-1 following the overall format of IEC 62368-1 and simplify and facilitate the application of these requirements.<\/p>\n

Robots traditionally are covered under the scopes of ISO documents, typically maintained by ISO TC 299. ISO TC 299 has working groups for personal care robots and service robots, and produces for example, ISO 13482, Robots and robotic devices \u2013 Safety requirements for personal care robots.<\/i><\/p>\n
