Test Method
Elcometer Testex Tape: ASTM D4417 Method B
In summary, ASTM D 4417 Method C and NACE RP0287-95 require the appropriate tape to be
rubbed onto the surface.
The thickness of the tape, when the thickness of the backing has been subtracted, gives the peak-to-
valley height of the surface.
Measurements should be made at an agreed series of locations, which characterise the surface.
