1. Context within the Coating Ecosystem SSPC-SP 3: Power Tool Cleaning is not a standalone cleanliness miracle; it is a compromise. In the hierarchy of surface preparation standards (from least to most aggressive): Solvent Cleaning (SP 1) → Hand Tool Cleaning (SP 2) → Power Tool Cleaning (SP 3) → Commercial Blast (SP 6) → Near-White Blast (SP 10) → White Metal Blast (SP 5).
Unauthorized copies often omit the "Notes" section, which contains legally binding clarifications (e.g., Note 5: "The term 'power tool cleaning' does not imply a specific surface profile" – which is critical for defense against adhesion lawsuits). Summary for the Reader SSPC-SP 3 is not "clean steel." It is mechanically abraded, de-dusted, loose-debris-free steel with permissible stains and tight mill scale. Use it only where coatings are forgiving and service environments are mild. For the full legal text, tables, and inspection checklists, purchase the official AMPP/SSPC SP-03 PDF – it is a 6-10 page document that has shaped industrial maintenance painting for over six decades. sspc-sp 3 pdf
