The Elcometer 138/2 Surface Contamination Kit provides materials to
collect a sample of contamination from a surface in accordance with
ISO 8502-6 (Bresle Method).
A solution is produced from the test surface using the Bresle method
and the pH, chloride concentration and iron concentration are then
measured using single-use test strips.

3 TEST PROCEDURE
The test procedure consists of two stages:
Stage 1: Produce a solution
Stage 2: Test the solution for chloride, iron or pH as required
3.1 BEFORE YOU START
1 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 or sample.
2 Ensure that all parts which come into contact with the test
solution are clean; the beaker, the syringe and the needle. Rinse
with pure water if necessary.
3.2 PRODUCING A SOLUTION
1 Remove the printed protective backing
and foam centre from the Bresle
patch.

R
a Pure water is available from Elcometer or your local Elcometer supplier, see Section 5 ‘Spares &
Accessories on page en-7.
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.
2 Apply the patch to the surface pressing
firmly around the perimeter of the patch to
ensure a complete seal and remove the
clear protective film cover using the
orange tab. a
3 Pour approximately 3ml of pure water into
the beaker, by eye. Fit a needle into the
syringe and suck 3ml into the syringe.
Throw away the remaining water in the
beaker, do not put the pure water back into
the bottle.
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 .
7 At the end of the period, extract as
much solution as possible and remove
c
the syringe from the patch .
8 Transfer the contents of the syringe
into the beaker.
9 Test the solution for chloride, iron or
pH as required - see Sections 3.4, 3.5
and 3.6.

3 TEST PROCEDURE (continued)
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.
3 Rinse all components of the test kit, other than the patch, in fresh,
pure water. The components can then be used again.
3.4 TESTING FOR CHLORIDE
1 Remove a titrator from the plastic bottle
marked ‘Chloride’ and replace the cap on
the bottle immediately.
 The test strips included in the kit have a
shelf life determined by the manufacturer.
Before using a test strip, always check that
the expiry date has not been exceeded.
The expiry date is marked on the test strip
container. Further information concerning
the use of test strips can be found in the
manufacturers’ instructions included in the
test strip container.
2 Insert the lower end of the titrator into the
solution. Do not allow the solution to
reach the yellow band at the top of the
titrator. Fluid will rise up the wick inside
the titrator by capillary action.
3 Allow the solution to completely saturate
the titrator wick; complete saturation is
indicated by the yellow band at the top of
the titrator changing to a dark blue colour.
4 Note the position on the numbered scale of the tip of the white
column which has become visible; this represents the Quantab
unit value.
5 Refer to the table on the bottle to convert the Quantab unit value
to chloride concentration; mg/L or ppm.
2
Note: The solution contains salt in a 3ml sample taken from a 12.5cm area.
Estimated salt / area as Sodium Chloride (according to ISO 8502-5):
2 2
µg/cm = 0.4 x concentration in ppm; mg/m = 4.0 x concentration in ppm

3.5 TESTING FOR IRON
1 Remove a test strip from the metal bottle
marked ‘Iron Test’ and replace the cap on
the bottle immediately.
 The test strips included in the kit have a
shelf life determined by the manufacturer.
Before using a test strip, always check
that the expiry date has not been
exceeded. The expiry date is marked on
the test strip container. Further
information concerning the use of test
strips can be found in the manufacturers’
instructions included in the test strip
container.
2 Insert the lower end of the test strip
into the solution (pH 1 to 7, 15°C to
25°C) for 1 second.
3 Remove the test strip from the solution
and shake off excess liquid from the strip.
4 Wait 10 seconds.
5 Compare the test strip with the scale on the metal bottle.
Determine which of the scale colours coincides most exactly with
that of the test strip. 2+
6 Read off the corresponding result in mg/I Fe or, if necessary,
estimate an intermediate value.
3+
For determination of Fe and should any other colour changes occur,
refer to the manufacturers’ instructions included with the test strip
container.
Note: The colour of the reaction zone on the test strip may continue to change after
the specified reaction time (10 s) has elapsed. This must not be considered as a
measurement.
If the colour of the reaction zone is equal to or more intense than the darkest
colour on the scale, repeat the measurement using fresh samples diluted with
2+
pure water until a value of less than 500mg/l Fe is obtained. This must then be
multiplied by the corresponding dilution factor.
The reading will be the concentration of iron in 3ml of water. To compare this
reading with that of another collection method, scale the volume of water.
2
The sample is taken from an area of 12.5cm . To compare with another
collection method, scale the area.

3.6 TESTING FOR pH
1 Remove a test strip from the plastic
container marked ‘pH 0 - 14’ and replace
the lid on the container immediately.
 The test strips included in the kit have a
shelf life determined by the manufacturer.
Before using a test strip, always check that
the expiry date has not been exceeded.
The expiry date is marked on the test strip
container. Further information concerning
the use of test strips can be found in the
manufacturers’ instructions included in the
test strip container.
2 Insert the coloured end of the test strip into
the solution to a depth sufficient to cover
all coloured squares.
3 Remove the test strip from the solution
and shake off excess liquid.
4 Holding the test strip as shown, compare the test strip with the
coloured scale on the paper insert inside the plastic container.
Determine which of the scale colour groups coincides most with
that of the test strip.
5 Read of the corresponding pH value (0 to 14).
Note: For weak solutions, leave the test strip immersed in the solution for a period of
up to 10 minutes until there is no colour change, then proceed to step 3 above.
