4.1.1

application procedure specification

APS

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

4.1.2

applicator

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

4.1.3

C glass

glass fibre that provides greater resistance to chemicals and is used in advanced composites, mainly used in the form of surface tissue in the outer layer of laminates used in chemical and water pipes and tanks

4.1.4

caulking

the process of applying a 98 % to 100 % solid catalysed epoxy material (caulking compound) on tank internal surfaces to fill pores/pits or to cover weld seams, lap joints, large projections, connections, etc.

Note 1 to entry: This is to provide a uniform gradual transition and smooth surfaces.

4.1.5

client

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

4.1.6

coat

paint, varnish or lacquer applied to surface in a single application (one layer) to form an evenly distributed film when dry

4.1.7

contractor

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

4.1.8

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 curing compound)

4.1.9

dew point

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

4.1.10

dry abrasive blasting

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

4.1.11

dry film thickness

DFT

thickness of a coat or coating system in its fully cured and dry condition

Note 1 to entry: The dry film thickness of coating is measured by film thickness calibrated gauge and expressed in mils or microns (1 000 microns is equivalent to 40 mils).

4.1.12

E glass

glass containing not more than 1 % by mass of alkali (calculated as Na₂O) and used for the manufacture of glass fibre

4.1.13

epoxy

resin containing epoxide functional groups that allow for curing by polymerization with a variety of curing agents

4.1.14

fibreglass lining

cold curing resin linings to repair and/or add strength to tank bottoms with fibre mat

Note 1 to entry: Examples are pure epoxies, phenolic epoxies, polyesters, vinyl esters being chemically cured with curing agents.

4.1.15

fibreglass reinforced lining

resin linings, usually polyester, vinyl ester or epoxies, into which layers of fibreglass are incorporated to enhance the lining’s structural capability, corrosion and chemical resistance performance

4.1.16

fibre mat

woven glass fibre that is used as reinforcement of the thermosetting resin (e.g. epoxy) lining to repair and/or add strength to tank bottoms

Note 1 to entry: Fibre mat is typically applied to a wet resin at about 450 g/m² area.

4.1.17

gel coat

final coat applied over the fibreglass lining laminate to seal the laminate surface and enhance water and hydrocarbon resistance

4.1.18

holiday

discontinuity in a lining (e.g. pinhole, void, crack, thin spot, and inclusion of foreign material) or contamination in the coating film that significantly lowers the dielectric strength of the coating

4.1.19

lining

material applied to the internal surfaces of a tank to serve as a barrier to corrosion and/or product contamination

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

4.1.20

manufacturer

company responsible for the manufacture of coating material(s)

4.1.21

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 may extend entirely through the film to the substrate and lead to a holiday.

4.1.22

pre-production trial

PPT

application of coating and inspection/testing of its properties, to confirm that the APS is able to produce a coating with the specified properties

4.1.23

surface profile

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

Note 1 to entry: It is typically Ra/Ry/Rz value.
