6.5 Surface Preparation (Including Touch-Up Preparation)
Immediately prior to priming, blasted surfaces shall be inspected by the following methods to
verify that the specified surface preparation has been achieved:
1. The anchor pattern shall be verified using Press-O-Film tape as described in ASTM D 4417
Method C. The measurements shall be recorded on COM-EF-844.
2. The degree of cleanliness shall be verified by comparison to SSPC-VIS 1. The cleanliness
shall be recorded on COM-EF-844.
6.6 Coating Application
1. Dry film thicknesses shall be measured using a Microtest Magnetic Film Thickness Gauge or
Purchaser-reviewed equal in accordance with SSPC-PA 2.
2. The dry film thickness gauge shall be calibrated to the Purchasers satisfaction at the
beginning of coating work and thereafter, regularly and whenever the Purchaser requests
recalibration.
3. Calibration of the film thickness gauge shall be made using the procedures in SSPC-PA 2.
Record the thickness for each coat as work proceeds as well as the total thickness of eachfinished coating system on COM-EF-844.
4. The entire surface of internal linings shall be inspected for holidays per NACE RP0188. When
testing hard-to-get-at locations around appurtenances and nozzles, a small sponge attachment
shall be used.
5. Areas containing holidays shall be locally sandblasted to bare metal, recoated with the same
system and retested for holidays. Detected holidays, correction and final holiday-free
inspection shall be recorded on the COM-EF-844.
6. The entire surface of splash zone coatings shall be inspected for holidays using a Purchaser-
reviewed high voltage spark type detector. The voltage setting shall be determined based on
Table 1 from NACE RP0188.
7. Areas containing holidays shall be locally sandblasted to bare metal, recoated and reinspected.
8. Areas found to contain runs, overspray, pinholes, sags and/or other signs of improper
application shall be repaired in accordance with the manufacturers recommendations at the
Suppliers expense.
6.7 Inspection by Purchaser
1. Work shall be subject to Purchaser inspection.
2. The Purchasers inspectors shall be given at least two days notice prior to the start of surface
preparation or coating application so that they can witness the work.
3. Work shall not proceed past each of the inspection hold points defined below without the
approval of the Purchasers inspectors.
a. Completion of surface preparation, prior to primer application
b. Completion of application of each coat (primer, intermediate and top-coat)
