Flake size as per ASTM A247 and ISO 945

Images of gray cast iron showing different sizes of flakes are submitted for image analysis with respect to ASTM A247 and ISO 945.

Figure 1. Typical field at 100X for graphite size class evaluation.

Figure 2. Typical field at 25X for distribution type evaluation.


Demonstrate the ability of the Clemex Vision image analysis system can evaluate the flake size class and distribution according to ASTM A247 and ISO 945. The methods and operations used are discussed in the report linked at the bottom of this page (click the Download PDF link below).


Measurements were performed on each distinct feature from the field of view. Automated statistics and graphs were generated and would be cumulated if analyzing several images. Final results can be printed directly from Clemex Vision. Raw data are linked to their respective objects for validation purpose. Raw data can also be exported in Excel format allowing to build an automated macro to find the size class.
