Learning Objectives• Update status of SSPC standards

useful to DOTs>Completed new standards>Completed revisions of standards >New standards projects starting in 2013

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

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)

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

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

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)

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

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

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

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)

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

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

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
