3.2.1 Hardware should be suitably designed to
withstand supply voltage variations and transients, ambient temperature
changes, vibration, humidity, electromagnetic interference and corrosion
normally encountered in ships.
3.2.2 The design of the hardware should ensure
ease of access to interchangeable parts for repairs and maintenance.
3.2.3 Each replaceable part should be simple to
replace and should be constructed for easy and safe handling. All
replaceable parts should be so arranged that it is not possible to
connect them incorrectly or to use incorrect replacements. Where this
is not practicable, the replaceable parts, including their means of
electrical connection, should be clearly marked.
