4.1.1 Physical Transverse Criteria should be defined for normal, abnormal and emergency
operating conditions of the systems on board a submarine, e.g. internal pressure
affected by the accidental release of a gas.
4.1.2 Physical Transverse Criteria may act in combination and have a cumulative effect.
Possible interactions are to be considered in the design of the submarine, systems,
equipment and components.
4.1.3 The impact of Physical Transverse Criteria on embarked personnel is to be understood
and suitable limits defined.
4.1.4 The systems, equipment and components are to be verified as being effective and safe
for the full range of Physical Transverse Criteria.
4.1.5 The restrictions Physical Transverse Criteria may place on submarine operation is to
be documented in the operational envelope for the submarine.
