CT10. Breaking news from ASTM Standardization Committee

CT10 – Digital Corrosion Rater

AD Systems provided an update on the progress of the field test of the CT10 Digital Corrosion Rater. The presentation is attached. This presentation was very well received. Sub Committee D02.14 decided that CT10 could be used in parallel to the visual rating during the ASTM Official ILS (Inter Laboratory Study) to establish the correlation between the NACE TM0172 and the D7548 test methods. The technicians who will visually rate the specimens will not have access to the CT10 ratings to avoid bias.

The Chairman of the D02.14 Committee and the entire audience seemed very excited to see the CT10 ILS results and finally get a method where subjectivity is completely removed from the test method and a Precision Statement is established. Many of the members proclaimed this technique would be the technique of the future for D7548 as well as D665 and NACE TM0172. The results of the ILS study should be detailed at the next ASTM D02 meeting in December in San Diego, CA – USA.
