Code and standards of FBE coating,BS EN ISO 8501-1 Surface preparation is the essential first stage treatment of the steel substrates before the application of any coating,and this is generally accepted as being the most important factor affecting the total success of corrosion protection system.The initial steel surface normally comply with rust grades A or B according to BS EN ISO 8501-1.
Surface preparation of steel substrates before application of paints and related products-Visual Assessment of Surface cleanliness.Rust grades and preparation grades of uncoated steel substrates after removal of previous coating.
Code and standards of FBE coating,The Elcometer-142 dust tape kit allows assessment of the quantity and size of dust particles on surface prepared for painting and coating application.(Pressure sensitive tape method).Prior to start testing remove three complete layer of tape from the roll.Take a piece of tape at least 200mm long and placed on the blasted surface,rub with your thumb along the length of the tape three times in each direction at a constant speed using firm pressure.
Pull the tape it away from the test surface,once removed hold the tape by ends only.Place the sticky side of the tape on the reports sheet,after that assess the quantity of dust and size by using 10X magnification glass.
ISO 8502-6 / ISO 8502-9
Measuring salt contamination using the bresle sample patch method accordance with ISO 8502-6 and ISO 8502-9.The test for salt contamination assessment of surface cleanliness- Test Procedure-Apply the sample bresle patch on the surface and pressing firmly around tha patch.Pour approximately 3ml of distilled water into the beaker,suck 3ml water into the syringe.Insert the syringe into the patch through foam at angel of 30 degree to the test surface.Inject the pour water into the patch during a suitable period of time re-inject the solution at least four times.At end of times period,extract as much solution as possible and remove the syringe from the patch.Fill the syringe water into the beaker after that put some solution in the gauge prove,make sure gauge should be calibrated.
