Actual strategies for high temperature testing and standardisation
Over the past years mechanical testing at high temperatures has evolved considerably. This has been fuelled by the industrial interest in structural application of a number of new, advanced materials such as monolithic ceramics and ceramic matrix composites (CMC) with higher temperature capability, and by the increased need to reduce the time-cycle from laboratory experiment to design use of mechanical property data. Also the trend towards total quality management in the field of mechanical testing represents a strong driving force for upgrading of existing and developing new standards. Standardization has not followed this evolution at the same pace and indeed now lags behind in three main areas. The first is the upgrading of existing standards to allow for closer tolerances on a number of testing parameters which may be required for reliable testing of the new generations of high temperature materials. The second area is that of testing methods which are routinely applied in laboratories, but for which a standard has not been developed yet. The third is related to the post-test activities such as evaluation and presentation of test results. In this paper, standardization issues in mechanical testing at high temperatures will be discussed and current efforts will be highlighted.
