WG 7

Cooperative multiple systems in connected home environments - Functional safety of electrical/electronic safety-related systems - AAL aspects

This Working Group specifies AAL specific functional safety requirements of electrical/electronic (E/E) safety-related systems for cooperative multiple systems that are operated together in a connected home environment. The AAL specific functional safety requirements are: - AAL specific Safety Integrity Level (SIL) definitions that account for different types of AAL users; and - a risk assessment procedure using the AAL specific SIL. These cooperative multiple systems may be installed and operated by AAL users, including operators who are not fully trained. The requirements are specified in accordance with the principles of the basic standard for functional safety, IEC 61508 (Functional safety of electrical/electronic/programmable electronic safety-related systems), and the other related standards including ISO/IEC 14762 (Information technology -- Functional safety requirements for Home and Building Electronic Systems (HBES)) and IEC 63044 series (Home and Building Electronic Systems (HBES) and Building Automation and Control Systems (BACS)).
