60079-14 IEC –
9.1.2 Avoidance of damage
Cable systems and accessories should be installed, so far as is practicable, in positions that
will prevent them being exposed to mechanical damage and to corrosion or chemical
influences (for example solvents), and to the effects of heat (but see also 126.96.36.199 for
intrinsically safe circuits). Where exposure of this nature is unavoidable, protective measures,
such as installation in conduit, shall be taken or appropriate cables selected (for example, to
minimize the risk of mechanical damage, armoured, screened, seamless aluminium sheathed,
mineral-insulated metal sheathed or semi-rigid sheathed cables could be used).
Where cable or conduit systems are subject to vibration, they shall be designed to withstand
that vibration without damage.
