For the purpose of this Standard, the following definitions
apply:
2.1
Dew point is the temperature
at which air is saturated with moisture.
2.2
DFT is dry film thickness.
2.3
Dust is loose particle matter
present on a surface prepared for painting, arising from blast-cleaning
or other surface preparation processes, or resulting from the action
of the environment.
2.4
Edge grinding is the treatment
of edge before secondary surface preparation.
2.5
“GOOD” condition is
the condition with minor spot rusting as defined in the Guidelines
on the enhanced programme of inspections during surveys of bulk carriers
and oil tankers (resolution A.744(18)).
2.6
Hard coating is a coating that
chemically converts during its curing process or a non-convertible
air drying coating which may be used for maintenance purposes. It
can be either inorganic or organic.
2.7
NDFT is the nominal dry film
thickness. 90/10 practice means that 90% of all thickness measurements
should be greater than or equal to NDFT and none of the remaining
10% measurements should be below 0.9 x NDFT.
2.8
Primer coat is the first coat
of the coating system applied in the shipyard after shop primer application.
2.9
Shop primer is the prefabrication
primer coating applied to steel plates, often in automatic plants
(and before the first coat of a coating system).
2.10
Stripe coating is painting of
edges, welds, hard to reach areas, etc., to ensure good paint adhesion
and proper paint thickness in critical areas.
2.11
Target useful life is the target
value, in years, of the durability for which the coating system is
designed.
2.12
Technical Data Sheet is paint
manufacturers’ Product Data Sheet which contains detailed technical
instruction and information relevant to the coating and its application.
2.13
Totally enclosed space is a
space which has no means of access and no ventilation.
2.14
Void space is an enclosed space
below the bulkhead deck, within and forward of, the cargo area of
oil tankers or the cargo length area of bulk carriers, excluding:
-
.1 a dedicated seawater ballast tank;
-
.2 a space for the carriage of cargo;
-
.3 a space for the storage of any substance (e.g.,
oil fuel, fresh water, provisions);
-
.4 a space for the installation of any machinery
(e.g., cargo pump, ballast pump, bow thruster);
-
.5 any space in normal use by personnel; and
-
.6 a double-side skin space of bulk carriers of
150 m in length and upwards which shall comply with the Performance
standard for dedicated seawater ballast tanks in all types of ships
and double-side skin spaces of bulk carriers adopted by resolution MSC.215(82).
For the purpose of this regulation, “cargo area”
and “cargo length area” are as defined in resolution A.744(18).
