invoke for these conditions:
9.1.7.2.
All aluminum components shall be fabricated from grades of aluminum
which show resistance to salt spray and moist conditions; e.g., Al-Mg base
alloys.

associated steelwork of the equipment shall be hot-dip galvanized according
to ASTM A 123. The thickness of the zinc shall be at least 100µm on
average, but the minimum thickness shall be not less than 90µm.
If dimensional or functional requirements do not allow hot-dip galvanizing,
steel parts will be electrolytically zinc plated to a minimum measured
thickness of 20µm.
9.1.7.6.
Components such as sleeves or bushings which may be fabricated having
an inner face of one metal and a supporting outer face of another, or
conductors which are used with connectors of a dissimilar metal are to have
their exposed interfaces protected against moisture.
