IEEE P7-4.3.2

Revision Standard - Active - Draft.
Additional specific requirements to supplement the criteria and requirements of IEEE Std 603™ are specified for programmable digital devices. Within the context of this standard, the term programmable digital device is any device that relies on software instructions or programmable logic to accomplish a function. Examples include a computer, a programmable hardware device, or a device with firmware. Systems using these devices will also be referred to as digital safety systems in this standard. The criteria contained herein, in conjunction with criteria in IEEE Std 603™, establish minimum functional and design requirements for programmable digital devices used as components of a safety system.

This standard serves to amplify criteria in IEEE Std 603(TM), to address the use of programmable digital devices as part of safety systems in nuclear power generating stations. The criteria contained herein, in conjunction with criteria in IEEE Std 603, establish minimum functional, performance and design requirements for programmable digital devices used as components of a safety system.
