The main part of standards on software engi-
neering is devoted to the description of software
(SW)lifecycle processes (supply and purchase,
requirement analysis, design, coding and testing,
integration, operation and maintenance, docu-
mentation, configuration management, quality
assurance, verification and validation, project
management). Moreover, a part of standards de-
scribe specific functions of software engineering:
terminology development, specification of data
and reports, measurement of SW characteristics,
use and reuse of commercial products, application
of instrumentation and formal methods.
IEEE standards form their own system inad-
equate to IEC standards. In particular, IEC focuses
on important to safety systems, IEEE focuses on
safety systems. It notes in (Johnson, 2002), that the
collection of IEEE and IEC standards have some
overlap, but in many cases cover significantly dif-
ferent topics. For example, IEEE standards go to
great depth covering environmental qualification

of many specific types of components, while IEC
covers the topic only at the general level. Con-
versely, certain IEC standards deal with specific
instrumentation and control functions, a topic area
where IEEE standards are largely mute.
Collaboration between IEC with IEEE was
realized as follow: two high level agreements
signed in 2007 and 2008 between the IEC and the
IEEE; technical collaboration started in 2009 be-
tween IEC/SC45A and IEEE/NPEC; publication
of IEC/IEEE standards on condition monitoring
took place in 2011 (IEC/IEEE, 2011). Drafts of
new IEC/IEEE standards include:

• Nuclear Power Plants: Electrical equip-
ment for safety systems- Qualiication.
• Nuclear Power Plants: Control rooms-
Computer based procedures.
• New Direction of Common Work: IEC/
IEEE standard, devoted to post-accident
monitoring.
