Tested under laboratory conditions in accordance with ISO 8502-9, the Elcometer 130 SSP provides equivalent measurements to the Bresle Patch Method.

To show equivalency of measurement between the Bresle Method and the Elcometer 130 SSP it is essential that all parameters are identical except the gauges under test.
For equivalency to be established, both gauges should read a similar value, taking into account the accuracy and resolution of each test.
Working with the School of Materials at the University of Manchester (UK) an automated, repeatable and reproducible doping method was developed to apply a known salt concentration uniformally over a large panel.
Over 200 individual tests were undertaken across a range of concentrations and blast profiles.
Surface salt concentration levels
Testing was undertaken under strict laboratory conditions, with each method tested in accordance with the manufacturer’s instructions.
“The Elcometer 130 SSP measurement equivalency is less than 0.46µg/cm² across all concentrations on smooth and blasted substrates, almost half the background contamination of a Bresle Patch.”
The Elcometer 130 SSP has undergone extensive side by side comparison testing against the Bresle Test Patch Method.
Background (inherent) contamination within the Bresle Test Patch has shown that the Bresle Test Patch has a background contamination range of 0.88µg/cm² (8.8mg/m2).
The variation in readings between the Elcometer 130 SSP and the Bresle Test method are significantly within the background contamination range of the Bresle Patches(0.88μg/cm²); being less than 0.41μg/cm² for concentrations below 8.0μg/cm², and less than 0.46μg/cm² across concentrations below 16.5μg/cm².
