Update on SSPC Standards Useful to the Steel Fabrication Industry

2014 North Central States ConsortiumOctober 6-8, 2014

Sioux Falls, SDWilliam L. Shoup,

SSPC Executive Director

Learning Objectives

• Update status of SSPC standards, certifications, and training programs useful to steel fabrication industry– Completed New and Revised Standards – Training and Certification

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

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

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

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

Quick Summary of ASTM D 4417Field 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”

D4417 Method AVisual Comparator

ASTM D4417Method B – Depth Micrometer

ASTM D4417Method C – Replica Tape

Obtain 2 measurements per area

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

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

ASTM D7127Stylus Profile Tracing Instrument

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)

Recently Revised Standards

• Mineral and Slag Abrasives (SSPC-AB 1) - 2013• 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

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

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 66261.24)

• Status: Published April 2013

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

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

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

PA 2 Nonmandatory AppendixMeasuring 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

PA 2 Nonmandatory AppendixMeasuring 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

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
