Which DFT statistics should be recorded in a daily inspection report, and why are they relevant to a good coating QC record?

From Carl Havemann of www.corrosioneducation.co.za on July 18, 2011:
     A record of the coating thickness is necessary to verify conformance to the specification and must include: (i) Max, Min, Mean and Standard Deviation. Standard deviation is useful in providing data on thickness consistency during application. (ii) State the DFT measurement standard used ie SSPC-PA 2 (iii) State the calibration method ie "calibrated on smooth disc with no correction factor for blast profile" (iv) Record the blast profile data (v) State the DFT instrument used and include a copy of the Calibration Certificate.

From Shabbir Mansoori of National Contracting Co.(INTAP) on June 20, 2011:
     Checking and drafting of dfts as per relavant standard, which prescribes minimum, maximum and average readings according to types of surfaces. This is strong evidence of applied coating/painting for QC records.

From jack wu of shanghai on June 20, 2011:
 Max Reading, Min Reading, Average Reading and surface profile(correction factor)

From gijo dominic of national contracting company on June 19, 2011:
      Lowest, highest, and average values for dft, each square meter or piece. This dft needs to be inconformance with manufacturer's recommendations.  So this must be recorded for the future reference.
