For the purpose of this Standard, the following definitions
apply:
2.1
Crude oil tanker is as defined
in Annex I of MARPOL 73/78.
2.2
Dew point is the temperature
at which air is saturated with moisture.
2.3
DFT is dry film thickness.
2.4
Dust is loose particulate 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.
2.5
Edge grinding is the treatment
of the edge before secondary surface preparation.
2.6
"GOOD" condition is the condition
with minor spot rusting as defined in the International Code
on the enhanced programme of inspections during surveys of bulk carriers
and oil tankers, 2011 (2011 ESP Code)
(resolution A.1049(27)). for assessing
the ballast tank coatings for tankers.
2.7
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. This
can be either inorganic or organic.
2.8
NDFT is the nominal dry film
thickness. 90/10 practice means that 90% of all thickness measurements
shall be greater than or equal to NDFT and none of the remaining 10%
measurements shall be below 0.9 x NDFT.
2.9
Primer coat is the first coat
of the coating system applied in the shipyard after shop primer application.
2.10
Shop primer is the prefabrication
primer coating applied to steel plates, often in automatic plants
(and before the first coat of a coating system).
2.11
Stripe coating is painting of
edges, welds, hard to reach areas, etc., to ensure good paint adhesion
and proper paint thickness in critical areas.
2.12
Target useful life is the target
value, in years, of the durability for which the coating system is
designed.
2.13
Technical Data Sheet is the
paint manufacturer's Product Data Sheet which contains detailed technical
instruction and information relevant to the coating and its application.
