1 Update on SSPC Standards Useful to the Steel Fabrication Industry
2014 North Central States Consortium October 6-8, 2014 Sioux Falls, SD William L. Shoup, SSPC Executive Director

2 Learning Objectives Update status of SSPC standards, certifications, and training programs useful to steel fabrication industry Completed New and Revised Standards Training and Certification MegaRust 2008

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 SSPC-PA 17, “Determining Compliance with Specified Profile Range” (2012)
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 Surfaces prepared by power tool and abrasive blasting are evaluated separately) Surfaces prepared using different power tools or separate blast pots are evaluated separately Number of readings at each location is determined by ASTM Method specified from D4417 or D7127, or minimum of 3 readings if not addressed in ASTM Method

5 SSPC-PA 17, “Determining Compliance with Specified Profile Range” (2012)
Average of readings at each location = location average Average of “location averages” = single “profile measurement” – must be in required range

6 ASTM Profile Measurement Methods
PA 17 references two ASTM standard methods used to determine steel surface profile ASTM D 4417 – used in the field, 3 methods Visual Comparator Depth Micrometer Replica Tape ASTM D7127 – mainly used in laboratory One instrument reads three characteristics – profile, peak count, and maximum peak-to-valley distance

7 Quick Summary of ASTM D 4417 Field Measurement of Surface Profile
Method A – Visual comparator Compare segments of physical standard to surface Method B – Depth micrometer (probe) Record highest of 10 gage readings at each of a specified number of locations Average of highest readings = “measurement” Method C – Replica tape Follow tape manufacturer directions to determine the “reading” on each tape Average of “readings” from 2 tapes = “measurement”

8 D4417 Method A Visual Comparator

9 ASTM D4417 Method B – Depth Micrometer

10 ASTM D4417 Method C – Replica Tape
Obtain 2 measurements per area

11 ASTM D7127 (Measurement of Abrasive Blast Cleaned Surfaces Using a Portable Stylus Instrument)
A second ASTM method for evaluating surface roughness Instrument is rarely used in industrial protective coatings industry Measures surface profile, peak count, and peak-to-valley depth

12 Summary ASTM D7127 – Stylus Profile Tracing Instrument
Take 5 traces of surface 1 inch apart Each trace is ½ inch long measures peak count, profile, and greatest distance from peak to valley Average of profile readings from 5 traces = 1 measurement

13 ASTM D7127 Stylus Profile Tracing Instrument

14 SSPC Guide 19 – “Selecting Coatings for Galvanized Steel” (2012)
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)

15 Recently Revised Standards
Mineral and Slag Abrasives (SSPC-AB 1) Determining Compliance with Dry Coating Thickness Requirements (SSPC-PA 2) – 2012 Field Methods for Extraction and Analysis of Soluble Salts on Steel and Other Nonporous Substrates (SSPC-Guide 15) – 2013

16 2013 Revisions SSPC-AB 1 “Mineral and Slag Abrasives”
Clarifies requirements for Qualification testing (supplier responsible) Conformance testing for verification upon receipt Quality control testing of media in shop or field for oil, conductivity per shift or 12 hour period

17 2013 Revisions SSPC-AB 1 Appendix B (nonmandatory unless specified as requirement) contains many requirements from MIL-A-22262(sh) Friability (must meet CARB requirements) Crystalline silica (must meet Class A –less than 1%) Soluble/total metal content (must meet California Title 22 Division 4 Section ) Status: Published April 2013

18 2013 Revisions to 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

19 PA 2 Options for Specifier
Thickness………. Gage Reading Spot Reading Area Measurement Level 1  Minimum Unrestricted As specified Maximum Level 2  120% of maximum Level 3  DEFAULT (same as current PA 2 requirement) 80% of minimum Level 4 150% of maximum Level 5  

20 Initial Nonconforming 100 ft2 Area
OK STOP Dashed line indicates boundary of area painted during work shift Suspect area preceding a nonconforming spot must be remeasured after corrections are made (Limit of area coated during work shift) MegaRust 2008

21 PA 2 Appendices of Interest to Fabricators
PA 2 is intended for use on large flat surfaces Appendices provide sample protocols for taking measurements on specific configurations such as beams or misc. metal parts Specifiers can reference appendices in project requirements

22 PA 2 Appendices of Interest to Specifiers
2 methods for measuring DFT on steel beams or girders and on miscellaneous metal parts Specify Full or Partial Determination Specify Coating Thickness Restriction Level

23 PA 2 Nonmandatory Appendix Measuring DFT on Steel Beams – Full Determination
Beam divided into 5 sections based on length 1 spot measurement in each of the 5 sections Each of 12 surfaces is measured independently (each side of web, top and bottom of each flange, toes, etc.) Average of 5 spots on each surface must be within specified range


25 PA 2 Nonmandatory Appendix Measuring DFT on Steel Beams – Partial Determination
Beams less than 20 ft long – 2 spot measurements on each surface Beams 20 to 60 ft long – 3 spot measurements on each surface Each spot measurement must conform to specified DFT

26 PA 2 Nonmandatory Appendix Full DFT on Miscellaneous Metal Parts
1 spot measurement on each surface of part If part has fewer than 5 surfaces, take multiple spot measurements on large areas for total of 5 spots If total area of part is over 100 ft2, take 5 spot measurements randomly distributed over each 100 ft2 area of part Specifier determines how many parts to measure and Coating Thickness Restriction Level

27 PA 2 Nonmandatory Appendix Partial DFT on Misc. Metal Parts
3 spot measurements, randomly distributed on part Each spot must conform to specified DFT Specifier determines how many parts to measure and Coating Thickness Restriction Level

28 PA 2 Nonmandatory Appendix Measuring DFT on Edges
