2.1 Anode is an electrode through which direct
current enters an electrolyte.
2.2 Ballast tank is a tank which is used for water
ballast and includes segregated ballast tanks, ballast double bottom
spaces and peak tanks.
2.3 Cathodic protection is a way of protecting
a steel surface from corrosion by installing sacrificial anodes, in
contact with the steel in the electrochemical seawater corrosion cell.
2.4 Dew point is the temperature at which air
is saturated with moisture.
2.5 DFT is the nominal dry film thickness.
2.6 Hard coating is a coating which chemically
converts during its curing process, normally used for new constructions
or non convertible air drying coating which may be used for maintenance
purposes. Hard coating can be either inorganic or organic.
2.7 LEL is the lower explosive limit.
2.8 Light colour is a colour of coating easily
distinguishable from rust.
2.9 Primer coat is the first coating applied in
the shipyard (to differentiate it from shop-primer).
2.10 Ship-primer means prefabrication thin primer
coating applied to steel plates, often in automatic plants.
2.11 Solvent means a volatile liquid capable of
completely dissolving a given binder.
2.12 Thinner means a volatile liquid that does
not necessarily dissolve the binder, but which is capable of reducing
the viscosity of the binder solution (vehicle), for example in reducing
the viscosity of a paint to spraying consistency.
2.13 TLV means threshold limit value.
