NACE (AMPP)
Thin Film Epoxies:
SP0490-2007
Enter Thickness in Mils

Thickness (mm)
Voltage
EXAMPLE: Epoxy, 0.016" thick
.016"= 16 Mils
sqrt(16) = 4
V = 525x4 = 2,100 volts
Asphalt/Coal Tar:
SP0274-2011
Enter Thickness in Mils
Submit
Thickness (mm)
Voltage
EXAMPLE: Coal Tar, 1/8" thick
1/8" = 0.125" = 125 Mils
sqrt(125) = 11.2
V = 1250x11.2 = 14,000 volts
Legend:
V = Test Voltage
T = Thickness
sqrt = Square Root
1 Mil = .001 inches
