Details. You are purchasing a downloadable pdf of this standard covers the requirements for power tool cleaning of steel surfaces. Power too. SSPC-SP3 Power Tool Cleaning. Removes all loose mill scale, loose rust, loose paint, and other loose detrimental foreign matter by power wire brushing, power. SSPC-SP3 power tool cleaning is frequently used when contamination to adjacent areas is a concern by sandblasting (SSPC-SP 5 & SSPC-SP 10) or is not.

D also considers the two methods interchangeable during the surface cleaning phase of the process. The standard also contains unique procedures for use on galvanized steel including inspection for a passivation treatment and wet storage stain.

Also, avoid excessively roughening or slicking the surface as that may also lead to premature paint failure.

The standard then requires oil, grease, and dust to be removed from the zp3 and the work inspected. A allows uncoated areas to be power-tool cleaned before repair with zinc rich paints in areas of less critical field exposure conditions. After a galvanized surface has been acceptably cleaned of oil, grease, and similar products, this brush blasting can be applied in order to create an acceptable profile.

Using good cleaning practices are essential to avoiding paint failure. The specification lists several different ways in which solvent cleaner may be applied to the surface including wiping or scrubbing the sspd with solvent, spraying solvent directly onto the surface, vapor degreasing, immersion, alkaline cleaners, and steam cleaning. The size and type of abrasive media to be used depends on the profile specified by the coating system to be used.

The ASTM specifications relevant to the hot-dip galvanizing industry often reference these surface preparation standards. However, A uses the white metal blast as the surface preparation standard for repairing a zinc coating using sprayed zinc.

D does not specifically call out this standard, but the procedure is very similar to that of D Therefore, the degree of ssppc tool cleaning can also be identified through the conditions system provided in the SSPC visual consensus references. Power abrading tools also acceptably remove mill scale according to the standard.

Materials and work areas shall be accessible to the inspector. The standard requires the surface to be free from all visible oil, grease, dirt, dust, rust, coating, oxides, mill scale, corrosion products, and other foreign matter when viewed without magnification. They are considered interchangeable in their use of smoothing the coating and removing zinc high spots before the zinc coating is further prepared.

Removing all weld slag and stratified rust with impact tools, using non-impact methods such as scraping to remove all non-adherent materials, and feathering an adherent paint coating, are all hand tool cleaning methods accepted by this standard. We will be updating and growing this site with more and more of industrial inspection related articles.

Power tool cleaning has less particulate contamination than other forms of cleaning, such as abrasive blasting. We are a non-profit group that run this website to share documents.

Mill scale, rust, and paint are considered adherent if they cannot be removed by lifting with a dull putty knife. However, some rust remaining at the bottom of pits is acceptable if the surface was pitted to begin with.

SSPC Surface Preparation Standards

D specifically calls out this standard with a condition that the water pressure be below psi. This fact makes power-tool cleaning an acceptable method for surface preparation of a hot-dip galvanized coating after it has been cleaned.

A, however, does not specifically call sapc SSPC-SP3 for the preparation of a damaged coating for repair by zinc rich paints. It provides photograph references for seven conditions of the surface, four unpainted and three painted surfaces. Notes Notes are not requirements of this standard. May 1, Authored by Daniel Barlow.

SSPC Surface Preparation Standards | American Galvanizer’s Association

The SSPC documents identify four conditions defined as conditions E, F, G, and H provide information on the previously painted surfaces that will undergo power tool cleaning for wp3. SSPC-SP3 requires power tools to be used in a manner that prevents the formation of burrs, sharp ridges, and sharp cuts. RustPaintProcurementSafetyBusiness. Thank you for interesting in our services.

Ssspc, it is best not to apply the same consensus reference photographs and the SSPC surface preparation standards for all projects because they will all vary based on the steel conditions and cleaning operations. D states that painting should be performed as soon as possible after power-tool cleaning or surface grinding. Through the use of impact or abrasion from these power tools, non-adhesive particles are removed in a faster and less expensive manner than some other cleaning methods. The table below lists the subjects discussed relevant to power tool cleaning and the appropriate Commentary Section.

We need your help! Oil, grease, and dust must be removed both before and after the cleaning procedure.
