  1. SSPC Update North Central States Consortium October 8-9, 2013Omaha, Nebraska William L. Shoup, SSPC Executive Director

  2. Learning Objectives • Update status of SSPC standards useful to DOTs • Completed new standards • Completed revisions of standards • New standards projects starting in 2013

  3. What is SSPC? • SSPC is a not-for-profit organization that provides industry standards for “good practice” in industrial painting • Resource for training and certification • Resource for current industry information • Exclusive focus on protective coatings

  4. New Standards Issued 2012 • Waterjet Cleaning of Metals - 4 Standards (formerly SSPC-SP 12/NACE No. 5) • SSPC-SP WJ-1/NACE WJ-1, Clean to Bare Substrate • SSPC-SP WJ-2/NACE WJ-2, Very Thorough Cleaning • SSPC-SP WJ-3/NACE WJ-3, Thorough Cleaning • SSPC-SP WJ-4/NACE WJ-4, Light Cleaning • Determining Compliance with Specified Profile (SSPC-PA 17) • Guide to Selecting Coatings for Galvanized Steel (SSPC-Guide 19)

  5. Joint Waterjetting Standards • SSPC-SP 12/NACE No. 5 now 4 separate standards based on level of cleanliness • WJ 1 – Clean to Bare Substrate • WJ 2 – Very Thorough Cleaning • WJ 3 – Thorough Cleaning • WJ 4 -- Light Cleaning • May be an alternative to dry blast cleaning for maintenance work

  6. WJ 2 Definition • Free of all visible oil, grease, dirt, rust, and other corrosion products except for • randomly dispersed stains of rust and other corrosion products • tightly adherent thin coatings • other tightly adherent foreign matter

  7. 2012 ChangesWaterjetting Standards • 2 new non-mandatory appendices for assessing levels of flash rust • wipe test (based on NSRP Flash Rust Evaluation Guidelines) • tape pull test (based on ISO dust level test) • Added distribution clarification in WJ-2 and WJ-3: Staining or tightly adherent matter limited to no more than • 5% of each 9 in2 area of surface (WJ-2) • 10% of each 9 in2 area of surface (WJ-3)

  8. SSPC-PA 17, Determining Compliance with Specified Profile Range • Take readings at minimum of 3 locations on each surface prepared by an individual piece of equipment used during a work shift or 12- hour period • Number of readings at each location is determined by ASTM Method specified from D 4417 or D 7127, or minimum of 3 readings if not addressed in ASTM Method • Average of readings at each location= location average • Average of “location averages” = single “profile measurement” – must be in required range

  9. Example: Determining Profile Compliance Assume ASTM D 4417 Method C (tape), and 1 blast pot and 1 power tool used on shift • Profile verified separately for each tool used • Identify three 6 x 6-inch locations for areas prepared by power tool and three 6 x 6-inch areas prepared by blast pot in which to take readings • Prepare two tapes in each of three locations prepared by blast pot, and three locations prepared by power tool cleaning • Average of readings in each of the 6 locations must comply with specified profile range

  10. PA 17 Extent of Nonconforming Areas • Similar to PA 2 procedure • Determine averages for locations spaced at 5-ft. intervals radiating in 4 equally-spaced directions from non-conforming area • Each location average must comply with project requirements • Stop measuring in a given direction when 2 consecutive locations are in compliance • Document location of nonconforming areas

  11. Dashed line indicates boundary of area prepared by single tool during work shift OK OK OK OK NO OK OK STOP STOP STOP STOP 5 ft 5 ft 5 ft 5 ft Initial Nonconforming Location OK OK 5 ft 5 ft 5 ft (Limit of area prepared during work shift)

  12. SSPC-PA 17 Process Control Option (if specified) • Appendix B provides option for specifying number of measurements • Based on process changes following acceptance of a project-specific “field standard” • Contractor prepares a 2 x 2 area at jobsite, documents list of process parameters listed in appendix (nozzle size, nozzle pressure, compressor size, hose length, etc.) after acceptance • Contractor must confirm profile remains in compliance if any of above process parameters occurs during production work • Measurements to determine compliance also required after completion of production work • Status: Published September 2012

  13. Guide 19 - Selecting Coatingsfor Galvanized Steel • Contains recommendations for selecting coatings for galvanized steel based on • Service environment (buried, marine, immersion, insulated, atmospheric • Condition of galvanized surface (new, weathered, deteriorated) • Extent of area being coated (repair, topcoat) • Status: Published November 2012

  14. Revised Standards Issued2012 to date • Mineral and Slag Abrasives (SSPC-AB 1) • Determining Compliance with Dry Coating Thickness Requirements (SSPC-PA 2) • Power Tool Cleaning to Bare Metal (SSPC-SP 11) • Commercial Grade Power Tool Cleaning(SSPC-SP 15) • Field Methods for Extraction and Analysis of Soluble Salts on Steel and Other Nonporous Substrates (SSPC-Guide 15)

  15. 2013 Revisions SSPC-AB 1 • Clarifies requirements for • Qualification testing (supplier responsible) • Conformance testing for verification upon receipt • Quality control testing of media in field for oil and conductivity • Appendix B (nonmandatory unless specified as requirement) contains many requirements from MIL-A-22262(sh) • Status: Published April 2013

  16. Additional AB 1 Requirements when Appendix B is Invoked • Friability (CARB test) – meet CARB requirements • Radioactivity (Gross Cobalt-60) – no more than 20.0 picoCuries per gram • Specific Cobalt-60 concentration less than 0.05 picoCuries per gram • Crystalline Silica Content (NIOSH Method 7603) – must be Class A • Hazardous material content (TCLP test) – non-hazardous

  17. 2012 Revisions SSPC-PA 2 • “Procedure for Determining Conformance to Dry Coating Thickness Requirements” • Options for specifying more or less stringent compliance requirements • Clarified process for defining extent of nonconforming areas • Added appendices with info on measuring DFT on edges, pipe exteriors • Status: Published May 2012

  18. PA 2 Options for Specifier
