1 Scope

This document specifies the general functional safety requirements for products intended to be integrated into HBES and BACS.

In addition, this document defines the functional security requirements for device interfaces intended to connect to the HBES/BACS network. This document does not...

An interface suitable for connecting to other networks.

Note 1.Another example of a network is the dedicated ICT network covered by IEC 62949.

This document does not provide functional safety requirements for safety-related systems.

Note 2.Appendix C provides examples of non-security-related HBES/BACS applications.

This document does not provide requirements regarding data protection and security.
