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.
One of the most advanced kits avalible. 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 mg/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.
