The bresle test kit is also known as chloride test kit or salt test kit or bresle patch method from www.caltechindia.com • The bresle method is used to determine concentration of soluble salts on metal surfaces prior to coating application, such as painting. Presence of salts can cause serious adhesion problems. Highly important bresle test kit need to evaluate chlorides or/and salt on surface of blasted cleaned steel surface. • It is essential that the level of contaminants on a surface is measured prior to application of the coating to ensure the quality of the coating and that its optimum lifetime is achieved. If the coating is applied to a contaminated surface, which is not properly prepared, it could fail prematurely resulting in costly re-coating and high maintenance costs • The bresle test will measure contamination of water-soluble salts and corrosion products on blast-cleaned steel. These compounds are almost colorless and are localized at the lowest point of the rust pits. Salts present after painting, chemical reactions can result in blister formation and accumulations of rust that destroy the adhesion between the substrate and the applied protective coating • The bresle kit is also suitable to determine the contamination of abrasives, shots or blast-media in use. This is to prevent the dissolved salts in the recycled abrasive media or water from re-contaminating the surface being cleaned. The bresle test can also be used for testing non-metallic abrasives for water-soluble salts and corrosion products by recording the conductivity of the deionized water using the same procedure under the section taking measurements • Factors are applied to the measured conductivity, depending on what is known or assumed about the salt contamination and various conditions, in order to yield meaningful measurements of contamination. Some of the variables are type of salt, volume of solution based on 2.5ml solution, and surface area of 12.5 cm2, temperature, equipment-specific scaling. • Reference Standards: • ISO 8502-6, Extraction for soluble contaminants for analysis -- The Bresle Method • ISO 8502-9, Field method for soluble salts by conductometric measurement • NACE SP0508-2010: Methods of validating equivalence to ISO 8502-9 on measurement of the levels of soluble salts • ISO 11127-6: Preparation of steel substrates before application of paints and related products. • For further details visit https://www.caltechindia.com/product/... or email us [email protected]
