This Chloride Test on steel or Salt Test on
steel using the Bresle Patch method will help to prevent coating failure
due to salts such as chlorides and sulphates contaminating the surface
prior to the coating application. This contamination can be tested
quickly and simply using the Bresle Method to ensure the correct surface
cleanliness.
The Bresle Patches used in the Bresle Kit are manufactured to the
highest quality with new materials that contain no chlorides, and are
guaranteed to adhere to blast-cleaned surfaces and not leak (samples
available on request).
Complying with International Standards: ISO 8502-6 and ISO 8502-9.
Easy to use, pour 10mls of distilled water into the beaker and
determine the conductivity using the Conductivity Meter. Take a Bresle
Patch and apply to the test surface. Fill the syringe with 2.5mls of
test water and insert through the adhesive foam into the test chamber.
Inject the contents, then extract back into the syringe. Repeat ten
cycles of injecting and extracting, then transfer the test water back
into the beaker. Measure the test water with the Conductivity Meter and
deduct the initial conductivity reading from the result. Multiply the
readings by 0.4 to give the quantity of salts in µg/cm² also known as
ppm, or by 4 for the quantity of salts µg/m².
The maximum permissible surface density of salts on the steel
surface prior to surface treatment depends on the type of paint to be
applied and what the finished material or product is to be used for.
Surface treatment specifications must, therefore, state the highest
permissible surface density of salts for each particular application.
Additional packs of Bresle Patches can be purchased to carry out further tests using this kit.
When high adhesion strength patches are required for testing on very
corroded or coarse-grade blasted steel, the Bresle Patches Plus are
available as an alternative to the standard Bresle Patches.
Supplied in an Industrial Foam-Filled Carrying Case with 50 Bresle
Patches (Standard Adhesion), 50 Bresle Patches Plus (High Adhesion),
Conductivity Meter, Calibration Solution, 3 × 5ml Syringes, 25ml Beaker
and 500ml Distilled Water.
