AD Systems CT10 for NACE Spindle Corrosion Test
CT10 BREAKING NEWS FROM STANDARDIZATION COMMITTEE
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.
Automated CT10 Digital Specimen Rater for NACE TM0172, ASTM D665, ASTM D7548
The corrosivity of petroleum products (gasoline and other distillates) must be determined before transportation through pipelines in order to control the internal corrosion of pipelines. The NACE TM01721 test for “Determining Corrosive Properties of Cargoes in Petroleum Product Pipelines” is considered a reference test and is the most widely used laboratory test for this purpose. The CT10 can rate NACE specimens and specimens from ASTM D665 and ASTM D7548.
The CT10 Digital Specimen Rater performs an objective and accurate rating of the test specimen
A new instrumental approach for measurement of corroded surface area has been developed by AD Systems in which the exact percentage of corroded area is accurately determined by an automatic instrument reducing test subjectivity. The innovative CT10 instrument provides a digital image of the surface of the specimen. Operation is based on a homogeneous lighting source, CCD camera, specimen rotation system, and specially designed Windows CE® application software. The test can be run unattended, which reduces labor costs.
The CT10 test is simple and straightforward. The specimen is prepared according to the specified corrosion test procedure and is placed in the test chamber of the CT10. The operator enters sample information, using an intuitive graphical interface with touch screen panel, and starts a specimen scan. Specific light is emitted onto the surface of the specimen. The specimen is rotated and images are taken. The software builds a flat image of the specimen surface, calculates the percentage of the corroded area and then translates that information into a NACE or ASTM rating. A detailed test report is ready in less than 5 minutes.
The CT10 is a versatile instrument for both research and routine applications at locations where NACE corrosion performance is evaluated:
• Inspection Laboratories
• Pipelines and Terminals
•Development of Rust and Corrosion Inhibitors
•Turbine Oil Condition Monitoring
• Research and Development
• Quick, accurate and objective rating
• Automatic specimen diameter verification
• Compact design, robust construction, installed in minutes
• The results are saved in an internal database and can be printed,transferred to a USB memory stick and/or sent to a LIMS
• Every test is fully documented and traceable
The CT10 strictly follows the test method removing the subjectivity inherent to the manual test and significantly improving repeatability and reproducibility with a final evaluation which eliminates disputes between the shipper and receiver of the product.
Note: Specifications subject to change.
