Caltech Engineering Services offers bresle test kit. The bresle test kit is also known as chloride test kit or salt contamination test kit, salt test kit or bresle patch method. Highly important bresle test kit need to evaluate chlorides or/and salt on surface of blasted cleaned steel surface. The Bresle method is used to determine concentration of soluble salts on metal surfaces prior to coating application, such as painting or coating.
Bresle test kit is best to determine salt contamination test for surfaces. 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 and NACE SP0508 Standards..
Many paint and coatings fail due to salts such as chlorides and salts contaminating the surface prior to the coating application. These salts can cause serious adhesion problems after time, therefore Importance of chloride and soluble salt is therefore essential to test and 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 bresle test kit.
Highly economical cost and easy method of bresle testing or salt contamination test can be used for production purpose of prior to coating applications immediately 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, and 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. Easy conversions for measuring chlorides. User manual gives easy conversions and conversions.
A test patch should be as clean as possible. Contamination of a patch can influences the results significantly. Bresle patches ensures adhesion and washability.
Bresle test kit complies with ISO 8502-6, which relates to the extraction of soluble contaminants using the bresle patch method. Bresle Patch Test also complies with ISO 8502-9 and NACE SP0508 which relates to the conductometric determination of soluble salts.
ISO 8502-6: Extraction for soluble contaminants for analysis – The Bresle Method
ISO 8502-9: Field method for soluble salts by conductometric measurement.
SP0508-2010: Methods of validating equivalence to ISO 8502-9 on measurement of the levels of soluble salts.
