The Elcometer 138 Bresle Kit and Patches provides 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 using
a conductivity meter.
These instructions incorporate two test methods:
 ISO 8502-6 / ISO8502-9
 US NAVY PPI 63101-000 (Rev 27)
The Elcometer 138 Bresle Kit and Patches can also be used in
accordance with ISO 8502-11; AS 3894.6-A and SSPC Guide 15.
a
For IMO PSPC , the surface salts should be measured and recorded.
The Elcometer 138 Bresle Kit and Patches can be used for this.

Note: The Elcometer 138 Conductivity Meter included in the test kit measures the
conductivity of aqueous solutions. The meter is 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.

3.1 BEFORE YOU START
1 Calibrate the conductivity meter, see Section .5 on page . 5 en-10
2 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.
3.2 TEST PROCEDURE
1 Remove the printed protective backing
and foam centre from the Bresle
patch.
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 Fill a syringe with 3ml of pure water.
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.
5 Inject the pure water into the patch.
Do not remove the needle.
 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.
b
6 During a suitable period of time ,
without removing the needle, suck and
re-inject the solution at least four
c
times .
3 TEST PROCEDURE: ISO 8502-6 / ISO 8502-9

R
b On un-pitted blast-cleaned areas, a period of 10 minutes has been found to be satisfactory, though this
time should be agreed by the interested parties.
c During steps 6 and 7, it is essential that no solution is lost. If any solution is lost, the test shall be rejected.

3 TEST PROCEDURE: ISO 8502-6 / ISO 8502-9 (continued)
7 At the end of the period, extract as
much solution as possible and remove
c
the syringe from the patch .
8 Measure the conductivity of the
solution using the Elcometer 138
Conductivity Meter, see Section 5.6 on
page en-11. Inject the sample directly
into the sensor cell. Rinse the sensor
cell several times with the solution to
be measured before taking the
reading.
3.3 AFTER TEST
1 Record the temperature of the solution.
2 Remove the patch from the surface and clean the surface. If
required, any adhesive residue from the patch left on the test
surface can be removed by wiping with a cloth moistened with a
suitable solvent. Ensure that the solvent will not damage the
surface before use.
