3.1.1

abrasive blast cleaning

surface preparation method that uses an abrasive propelled by air pressure, centrifugal force, or water pressure to clean and usually to profile a surface

3.1.2

application procedure specification

document describing procedures, methods, equipment and tools used for coating application

3.1.3

applicator

contractor or subcontractor having the technical capability, knowledge, equipment, qualified personnel that is approved by the client for the coating processes as required by this document

3.1.4

coat

one layer of protective coating or paint applied to the surface in a single application to form an evenly distributed film when dry

3.1.5

contractor

vendor or company that agrees to furnish materials and/or perform specific project/services to the client

3.1.6

curing

chemical process of developing the intended properties of a coating/polymerized product in the lining system, generally due to a reaction between two or more chemicals (e.g. resin and curative)

3.1.7

client

entity for which professional services are rendered or person that receives a product

3.1.8

dew-point

temperature of a given air/water vapour mixture at which condensation starts, because its maximum water content saturation is reached at that temperature

3.1.9

dry film thickness

thickness of a coat of paint, layer of tape or coating system in its fully cured condition

3.1.10

epoxy

resin containing functional epoxy groups that allow for curing by polymerization with a variety of curatives

3.1.11

grit abrasive

angular or irregularly shaped particles of abrasives

3.1.12

holiday

discontinuity in a lining or contamination in the coating film that significantly lowers the performance of a coating

Note 1 to entry: Examples of discontinuity in a lining are pinhole, void, crack, thin spot, and inclusion of foreign material.

3.1.13

lining

internal coating

Note 1 to entry: The term 'coating' is also used for the purposes of this document.

Note 2 to entry: Internal coating can be applied to the internal surfaces of a tank vessel to serve as a barrier to corrosion and/or product contamination, for example.

3.1.14

novolac

phenol-formaldehyde resin with formaldehyde to phenol molar ratio of less than 1

3.1.15

phenolic

resin of the phenol-formaldehyde type

3.1.16

pinhole

small film defect characterized by small pore like flaws in the lining that would permit corrosion of the substrate under the conditions for which the lining is designed

Note 1 to entry: A pinhole can extend entirely through the film and lead to a holiday.

3.1.17

surface profile

micro-roughness of a surface, generally expressed as the average height of the major peaks relative to the major valleys
