ISO/IEC 14762:2009（E）根据功能安全基本标准IEC 61508的原则，规定了HBE的一般功能安全要求。本国际标准规定了家用和建筑电子系统（HBES）产品和系统的功能安全要求。HBES是一种多应用总线系统，功能通过公共通信过程分散、分布和连接。如果该设备或系统没有特定的功能安全标准，则该要求也可能适用于家庭或建筑控制系统中连接的任何设备的分布式功能。 本国际标准仅针对HBES产品。本国际标准中的HBES和HES产品适用于非安全相关应用。

ISO/IEC 14762:2009(E) specifies the general functional safety requirements for HBES following the principles of the basic standard for functional safety IEC 61508. This International Standard sets the requirements for functional safety for Home and Building Electronic Systems (HBES) products and systems, a multi-application bus system where the functions are decentralised, distributed and linked through a common communication process. The requirements may also apply to the distributed functions of any equipment connected in a home or building control system if no specific functional safety standard exists for this equipment or system. This International Standard only addresses HBES products. HBES and HES products in this International Standard are for non-safety related applications.
