The Elcometer 138 Bresle Salt Kits provide all the materials and
equipment required to determine the surface chloride contamination
level.
Chloride salts are extracted from the surface using the Bresle Patch
method and the chloride content of the test solution is measured
a
using the Elcometer 138 Bresle Salt Meter or Elcometer 138
a
Conductivity Meter supplied.
These instructions incorporate two test methods:
Ÿ ISO 8502-6 / ISO8502-9
The Elcometer 138 Bresle Salt Kits can also be used in accordance with ISO 8502-11; AS 3894.6-A and
SSPC Guide 15.
b
For IMO PSPC , the surface salts should be measured and recorded. The Elcometer 138 Bresle Salt
Kits can be used for this.
Note: The Elcometer 138 meters measure aqueous solutions. They are NOT designed to measure solids, organic solvents,
surfactant, oil, adhesive, alcohol, strong acids (pH: 0 to 2) or strong alkalis (pH: 12 to 14). The life of the sensor will be
extremely short if these substances are measured.
Ÿ US NAVY PPI 63101-000 (Rev 27)

2 Apply the patch to the surface pressing firmly around the perimeter of the
patch to ensure a complete seal. If using the Elcometer 135C Bresle Test
Patch, remove the clear protective film cover using the orange tab.
3 As the test is extremely sensitive, clean latex or nitrile gloves should be
worn during the extraction of soluble salts to prevent contamination of the
surface.
4 If necessary, any air can be evacuated into the syringe and allowed to stay above the
water in the syringe. Take care not to re-insert the air during steps 6 and 7.
5 Inject the pure water into the patch. Do not remove the needle.
1 Remove the printed protective backing and foam centre from the Bresle
patch.
3 Fill a syringe with 3ml of pure water.
3.2 TEST PROCEDURE
4 Insert the syringe into the patch through the spongy foam perimeter at an
angle of approximately 30° to the test surface so that it passes through the
foam into the compartment formed by the elastomer film and the test
surface. If the patch is positioned in a difficult position bend the needle as
required.
2 Calibrate the Elcometer 138 Meter, see Appendix A Section A5 on
page en-19.
1 If using the Elcometer 138 Bresle Salt Meter, press the MEAS button to set
the measurement mode to ISO.
