1. COATING STANDARD
Primary surface preparation
- Blasting and profile: Sa ½ (profile: ㎛) (average?) – ISO
* restriction: humidity 85% or above, surface temp. below 3℃ - ISO /3
* surface cleanliness and roughness profile check before application
- Salt limit(NaCl): ≤ 50 mg/㎡ (ISO Conductivity test)
- Shop primer:
* Inhibitor free zinc silicate based or equivalent
* Compatibility with main coating system: shall be confirmed by coating manuf.

2. COATING STANDARD
Secondary Surface Preparation(SSP): Steel condition - Edge Grinding
The steel surface should be prepared so that the coating selected can achieve an even distribution at the required NDFT and have an adequate adhesion by removing weld spatter and any other surface contamination in accordance with ISO grade P2.
Edges to be treated to a rounded radius of minimum 2mm, or subjected to three pass grinding or at least equivalent process before painting.
The amount grinding activities will tremendously be increased at block assembly stage.
A strong necessity for development of a grinding tool or process to mitigate the huge burden for labor and progress management.

3. COATING STANDARD
SSP – surface treatment
At block assembly stage
Damaged surface of shopprimer and welds: SIS Sa 2½ ( ISO )
Compatible intact surface of shopprimer: Sweep blasting, high pressure water washing or equivalent method. (cf. compatible zinc silicate shop primer - cross over with other epoxy coatings: appdx. 1)
Intact shop primer not compatible with the main coat: Sa 2 (70% removal)
After erection
Butts: SIS St 3 or better or Sa 2½ where practicable. (ISO )
Small damages up to 2% of total area: St 3
Contiguous damages over 25m2 or over 2% of the total area of the tank: Sa 2½ (definition of damage, calculation of damaged area?, 순차적인 덧칠로 해결?)
Block division, erection procedure, working process should be take into account the limit of the amount of coating damages, erection butts to avoid the application of the blasting after erection.

4. Sampling of Current Standard for DUST grade
COATING STANDARD
i Dust grade “1” for dust size class “3” to “5” by means of adhesive tape test (ISO )
Ii Dust size classes “1” and “2”: shall be removed if visible
(naked eye)
SSP - DUST
Dust Size (ISO )
0 : Particles not visible under x10 magnification
1 : Particles visible under x10 magnification but not with normal or corrected vision(usually particles less than 50㎛ in diameter)
2 : Particles just visual with normal or corrected vision (usually particles between 50㎛ and 100㎛ diameter)
3 : Particles clearly visible with normal or corrected vision(particles up to 0.5mm in diameter)
4 : Particles between 0.5mm and 2.5mm in diameter
5 : Particles lager than 2.5mm in diameter

COATING STANDARD
ISO : Extraction methodology (Bresel only ?)
ISO : Assessment of soluble salt by conduct metric
Soluble salt limit
≤ 50 mg/m2 of NaCl (Pre-washing is not explicitly required)
A test result for the comparison of the content of Sodium Chloride in Total Dissolved Salt

8. ANNEX 3 DFT measurements
The following verification check points of DFT are to be taken:
.1 one gauge reading per 5 m2 of flat surface areas;
.2 one gauge reading at 2 to 3 meter intervals and as close as possible to tank boundaries,
but not further than 15 mm from edges of tank boundaries;
.3 longitudinal and transverse stiffener members:
One set of gauge readings as shown below, taken at 2 to 3 meters run and not less than
two sets between primary support members;
Note: Arrows of diagram indicate critical areas and should be understood to mean indication for both sides.
.4 Three(3) gauge readings for each set of primary support members and 2 gauge readings for each set of other members
as indicated by the arrows in the diagram;
.5 for primary support members (girders and transverses) one set of gauge readings for 2 to 3 meters run as shown in
figure 3 above but not less than three sets;
.6 around openings one gauge reading from each side of the opening;
.7 five gauge readings per square meter (m2) but not less than three gauge readings taken at complex
areas (i.e. large brackets of primary support members); and
.8 Additional spot checks to be taken to verify coating thickness for any area considered necessary by the coating inspector.
