How to Ensure Accurate Dry Film Thickness Readings
SSPC-PA 2 was originally published as a temporary standard 40 years ago in 1973 (73T) as “Measurement of Dry Coating Thickness with Magnetic Gages.” The standard referenced gages like the one shown in Fig. 1, which are now all but obsolete. The standard has been updated on multiple occasions. … See more SSPC-PA 2 addresses two types of DFT gages, both of which are supplied by a variety of manufacturers. Magnetic pull-off gages are … See more To help assure the reliability of the coating thickness measurements, ASTM D 7091 describes three operational steps that must be performed before taking the measurements. These steps are (1) gage calibration, (2) … See more The accuracy of Type 1 (magnetic pull-off) gages is verified by placing the gage probe onto a certified coated thickness standard (Figs. 4 and 5). A one-point or two-point accuracy … See more To guard against measuring with an inaccurate gage, SSPC-PA 2 requires that gage accuracy be verified (at a minimum) at the beginning and end of each work shift according to the procedures described in ASTM D … See more WebA lower DFT of the zinc-containing primer provides less anode material (zinc dust), while a high-er DFT provides more anode material. Al-though the electrochemical potential (volt) between the zinc and steel remains the same, the size of the anode deter-mines the electrochemical capacity (am-pere-hours).
