It is good practice for the NACE Inspector to have instrument calibration certificates available:

Due to a previous premature coating failure the owner has required the original coating applicator to return to remove and replace 10,000 square feet of a failed three coat system at the applicator's cost. Due to the financial implications of another failure, the owner has offered you the job as the NACE CIP Level 1 Coating Inspector and explained that he expects you to be his "insurance policy" for this job. You have never been involved in a warranty job before and are unfamiliar with the coating system.
Your preferred FIRST course of action is to:

You are the NACE Inspector on a job where the Owner's specification requites you to perform a twice daily check of blast pressure at the nozzle. It is now day 30 on the job and all of your readings have been within compliance. The Contractor complains that these checks taking up much time and in view of the compliant results they are unnecessary.
Your FIRST preferred course of action is to:

A single application coating film has a measured dry film thickness (DFT) between 4 and 5 mils (between 100 and 125 microns). The volume solids of the coating immediately before application were 67%, What wet film thickness (WFT) was applied?

Excess moisture during holiday testing can cause erroneous indications by creating a path across the surface of the coating to pinholes previously detected, or directly to the signal return connection.
