The surface, when viewed without magnification, shall be free of all oil, grease, dirt, visible mill scale, rust, corrosion products, oxides, paint, or any other foreign matter. SA1. SA2. Blasted Steel Surfaces Those issued by independent organ - isations • ISO +2 (surface cleanli-ness) • STG Guide No.
(pressure water jets) • SSPC-VIS 4/NACE VIS 7 (waterjetting–visual) • SSPC-SP 12/NACE No. 5 (waterjetting–written) • SSPC-VIS 5/NACE VIS 9 (wet abrasive blast cleaning) spects of surface quality are becoming. Lightly rusted, uncontaminated, uncoated steel surfaces with no tight mill scale are the easiest steel surfaces to abrasive blast.
All of the following affect abrasive blasting production. Rust pitting and heavy corrosion will require additional cleaning effort, especially in cleaning the pits. Initial surface condition. Structural steel elements in new structures are usually either hot rolled sections or fabricated plate girders.
The initial steel surfaces normally comply with rust grades A or B according to BS EN ISO Material that is pitted, i.e. rust grades C or D, should be avoided if possible, since it is difficult to clean all the corrosion products from the pits during.
Demanding circumstances require specialist equipment. The Airblast ranges of abrasive blasting and painting equipment offer increased performance, operator safety, and reduced operational costs.
Sand blasting, shot blasting, dustfree vacuum blasting, slurry blasting and water blasting all have specific applications where environmental, operator, and access concerns are present.
(texture) of abrasive blast cleaned steel. The complete set includes an illuminated, hand-held magnifier and three metal discs replicating surfaces cleaned with various grades of grit, sand.
Here is a list and brief summary of the surface preparation standards used in the hot-dip galvanizing industry with a brief summary of each. SSPC-SP1 Solvent Cleaning. The method of solvent cleaning is intended to remove all visible oil, grease, soil, drawing and cutting compounds, and all other soluble contaminants from steel surfaces.
Steel with the millscale layer intact and very minor, or no Class 1 (SP-7/N4) Very light, whip over blast clean with removal of loose surface contaminants.
Rust Grade B. Steel with spreading surface rust, and the millscale commenced flaking. Blast Class 2 (SP-6/N3). SSPC VIS 1 Visual Standards for dry abrasive blast, revision Febhas over 50 full-colour photos of previously-coated and uncoated rusted steel before and after dry abrasive blast.
Also includes a selection of white metal, near white, commercial and brush-off finishes. Steel specimens ( mm wide x mm long x 3 mm high) were coated with a commercial epoxy primer (red-brown) to clearly distinguish the blast-cleaned surface and the non-cleaned steel.
The coated specimens were blast cleaned to a White Metal finish (SSPC-SP 5 or Sa 3) with the abrasive flow rate adjusted through the abrasive me-tering valve. D Steel surface on which the mill scale has rusted away and on which considerable pitting is visible to the naked eye.
Preparation grades. Scraping and wire-brushing It is assumed that prior to treatment the steel surface has been cleaned of dirt and grease, and that the heavier layers of rust have been removed by chipping. This visual standard includes a series of 92 pictorials, covering both primary and secondary preparation (in before and after shots of the same surface) of new primary surface preparation, differentation is given according to abrasives used and levels of surface secondary.
Standard for Surfaces of New Steel Airblast Cleaned with Sand Abrasive," NACE Standard TM; and as described below. New SSPC/NACE wet abrasive blast cleaning (WAB) standards were approved in August The standards define five degrees of cleaning that are created using a mixture of abrasive and water.
The mixture is created in one of three ways: water is injected into the dry abrasive blast stream, abrasive is injected into a pressurized water stream, or. Near-white metal blast cleaning is to be used to clean unpainted or painted steel surfaces prior to applying a new protective coating or lining systems.
SSPC-SP 10/NACE No. 2 removes all dust, coating, and mill scale. The limit of staining permitted for near-white metal blast cleaning is no more than five percent of each unit area of the surface.
Abrasive blasting won’t remove oil and grease – it just smears them over the surface, causing premature coatings failure. Visible deposits of oil, grease and dirt must be spot cleaned prior to abrasive blast cleaning. SP 1 is a prerequisite to the other SSPC abrasive blasting specifications.
"Abrasive Blasting Respiratory Protective Practices" --and referenced hereaft er as lithe NIOSH surveyll --indicate that abrasive blastillf. is used most often to clean iron and/or steel surfaces. Other surfaces commonly treated by abrasive blastL~gtec~~iquesinclude maso~ry(brick, stone, concrete.
ISO is the "visual standards for cleanliness", and this cannot be equated to surface roughness because it is a visual standard for cleanliness and not a roughness standard. We gave an analogous example that strawberries can be clean or dirty irrespective of the size of the slices.
D A Bayliss FlCorrT, FTSC, in Plant Engineer's Reference Book (Second Edition), Structural steel (thickness greater than 5 mm) Abrasive blasting Abrasive blasting is generally the most suitable and reliable method of obtaining a visually clean surface and a satisfactory surface profile.
Dry abrasive blast cleaning should be used on new steelwork where the main contaminant is.

2) Steel Structures Painting Council. ISO is a pictorial standard relating to surface cleanliness, amongst other methods, though abrasive blasting. The original condition of steel surfaces prior to blasting are depicted in various stages of corrosion as follows: Grade A Steel surface largely.
SSPC STANDARDS Standards, technology reports, guides, and qualification procedures are the cornerstones of the SSPC mission. As the foundation for all SSPC training conducted globally, they serve to ensure the highest degree of quality, productivity, and safety in the protective coatings industry.

They are developed through consensus collaboration of SSPC technical committee. Scope. This standard covers the process and materials required for the abrasive blasting of aircraft and missiles components. Process description.

E. st Street, Suite A Broken Arrow, OK () DESCRIPTION. The following informational data is provided as an estimating tool for dry abrasive blast operation in the preparation of steel and concrete substrates.the degree of rusting before cleaning and the degree of cleaning of steel surfaces prior to painting.
Three methods for visual standards have evolved be-cause of differences in the practice of using visual standards throughout the world.
In Europe, the visual standards (Method A) are used as the primary means of determining the degree of.
