The voltage calculator included in the Elcometer 266 DC Holiday
Detector is programmed with the following standards:
APPENDIX A: STANDARDS
ASTM G6-83
AS3894.1:F3 1991
NACE SP0188-2006
ASTM G62-87
AS3894.1:F4 1991
NACE SP0490-2007
AS3894.1:F1 1991
ANSI/AWWA C213-91
NACE RP0274-04
AS3894.1:F2 1991
EN14430:2004
Other standards which do not derive the test voltage directly from the
coating thickness are not available within the Voltage Calculator
function. Testing to these standards is still possible however, by
setting the test voltage manually - see Section 9.2 ‘Manually Setting
the Voltage’ on page en-18.
The Elcometer 266 DC Holiday Detector can be used in accordance
with the following list of standards and test methods:
