Test Method for Catalyzed Titanium

This test method is for anodes comprised of a titanium substrate to which a mixed metal oxide (MMO) catalytic coating has been applied. This test method accelerates the time-to-failure by operating the anode at higher current than the application's design requirements.

The user should not imply that this test method is mandatory for any application of these anode materials.

Alternatively, the user may elect to use the manufacturer's rating instead of developing the test methodology independently.

Limitations

Accelerated testing should provide conservative results by stressing the anode more severely than normal applications. See Appendix A (Nonmandatory) for further discussion.

All manufacturers' products may not perform identically. Comparing test samples to a correlation curve established for a different manufacturer's product may lead to erroneous results.

The result for a sample run in the accelerated life test may be used to validate its performance at the design current density only if the correlation curve has been established for that material. See Appendix B (Nonmandatory) for development of the correlation curve using this test method.

This test method is not an acceptance criterion. It may be used to develop a test criterion as shown in Appendix C (Nonmandatory).

This test method outlines the test conditions that must be maintained for effective comparisons.

Varying the test conditions may have a significant effect on the sample lifetime, leading to erroneous results.

The test method as described in this standard should not be interpreted as being the only correct test method that may be used.
