Dear All,

While checking the DFT of finished painting on pipe spool (NPS 1/2" to 1") which required DFT range of minimum 275 microns to maximum 400 microns as per the client specification and standard, and the DFT reading encountered some measured individual gauge reading 253, 221, 237, 249, 252, 239 microns and average of some spot reading 246 microns which are less than minimum range 275 microns,

Kindly give you valuable feedback is plus or minus 20% as per SSPC PA 2, can be applied to this minimum 275 and maximum 400 microns, when a minimum and maximum DFT prescribed in the client Specification.
