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

• Determining Compliance with Specified Profile
  (SSPC-PA 17)

  (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

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

11
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

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

14
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

15
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)
