Bresle test

The Bresle method is a method used to determine the concentration of soluble salts on surfaces prior to coating applications to safe your Building, House, home. These salts can cause serious adhesion problems after time.The Bresle method is the industry's standard for determining if a surface can be coated.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.

The bresle test kit also known as chloride test kit or salt test kit is highly important instrument to evaluate chlorides or/and salt on surface of steel surface. Bresle test kit is supplied with all the necessary items including the bresle test patches, syringes, distilled water, calibration solution and conductivity meter to test for soluble salt and surface contaminants on blasted surfaces in compliance with ISO 8502-6 & ISO 8502-9.
Many coatings fail due to salts such as chlorides and salts contaminating the surface prior to the coating application. Importance of chloride and soluble salt is therefore essential test recommended by leading users of oil & gas, marine vessels, offshore, pipe coating, steel structures & other industries. Bresle test can be performed quickly at site, shop and at most locations quickly and simply using the Bristle Test Kit.
Bresle testing cost is highly economical and can be used for production of coated pipes or after surface blasting at number of locations.
The Bresle Patch is attached to the surface, the distilled water is injected with a syringe into the Bresle Patch and then extracted, this is repeated ten cycles of injecting and extracting the liquid in the Bresle Patch. This liquid is then measured with the Conductivity Meter will measure the quantity of salts in both µg/cm2 (ppm) and mg/m2
Complies with ISO 8502-6, which relates to the extraction of soluble contaminants using the bresle patch method and ISO 8502-9, which relates to the conduct metric determination of soluble salts.
The Bresle Method utilizes the difference of conductivity of salts in water, each salt having a different conductivity in water. The correlation between concentration and conductivity can be found in “Handbook of Chemistry and Physics”. This relationship between concentration and conductivity is useful only if the dissolved salt is known. Fortunately, not every salt causes the same increase in conductivity. Sodium chloride, a large component of the salt in sea water, causes a big increase in conductivity with increased concentration.
Salt residue is first dissolved after applying a special patch. This patch has a hollow opening which is, after being applied to the test surface, injected with deionized water. Soluble salts present on the surface are dissolved in the deionized water. The extracted fluid is filled up to a specified volume and the conductivity is measured. From this conductivity the amount of soluble salts measured as sodium chloride can be determined.
Climate Required for Brestle Test
Each generated soluble salts report should include climate conditions and substrate temperature. The ISO 8502-6 standard demands that the test has to be done at 23°C and a relative humidity of 50%. Any deviation from the defined parameters has to be reported and agreed upon by both inspector and customer. Surface temperature also influences the test, meaning that this parameter also needs to be recorded. During arbitration the lack of these recorded value’s also will render the acquired results invalid. A Dewcheck is a recommended method to measure all these conditions.
Although the above show there is a lot of “science” behind proper testing for salt contamination, inspectors can benefit from ready-made test kits which are available on the market, making these kind of tests quite simple.
The recently updated TQC Bresle kit is the first to support this new technique and enables inspectors not only to work faster but also produce more accurate results. The combination of the new technique, high quality gauges and patches makes the kit the ultimate inspection set for arbitration.
