3.1.1 The IBS should comply with all applicable
IMO requirements and recommendations. Parts executing multiple operations
should meet the requirements specified for each individual function
they control, monitor or perform.
3.1.2 Each "part" of an IBS should meet the relevant
requirements of resolution A.694(17) and
their associated technical testing standards. In consequence, the
IBS is in compliance with these requirements without further environmental
testing.
Note "part" is meant to be - for example - an individual module,
equipment or subsystem.
3.1.3 A failure of one part should not affect
the functionality of other parts except for those functions directly
dependent upon the information from the defective part.
