Learning Objectives
• Update status of SSPC standards, certifications, and training programs useful to steel fabrication industry– Completed New and Revised Standards – Training and Certification
![Page 3: 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,](https://reader036.fdocuments.us/reader036/viewer/2022062322/56649cbb5503460f94983044/html5/thumbnails/3.jpg)
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
![Page 4: 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,](https://reader036.fdocuments.us/reader036/viewer/2022062322/56649cbb5503460f94983044/html5/thumbnails/4.jpg)
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
![Page 5: 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,](https://reader036.fdocuments.us/reader036/viewer/2022062322/56649cbb5503460f94983044/html5/thumbnails/5.jpg)
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
![Page 6: 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,](https://reader036.fdocuments.us/reader036/viewer/2022062322/56649cbb5503460f94983044/html5/thumbnails/6.jpg)
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
![Page 7: 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,](https://reader036.fdocuments.us/reader036/viewer/2022062322/56649cbb5503460f94983044/html5/thumbnails/7.jpg)
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”

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
![Page 12: 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,](https://reader036.fdocuments.us/reader036/viewer/2022062322/56649cbb5503460f94983044/html5/thumbnails/12.jpg)
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
![Page 13: 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,](https://reader036.fdocuments.us/reader036/viewer/2022062322/56649cbb5503460f94983044/html5/thumbnails/13.jpg)
