CEN/TC 184 Advanced technical ceramics
Pre Standard
81.060.30 Advanced ceramics
Withdrawn
This Part of ENV 820 describes a procedure for undertaking flexural creep tests at elevated temperatures on advanced technical ceramics, mainly for the purposes of comparison of deformation behaviour of materials under stressed conditions and under any appropriate atmospheric condition.
NOTE This prestandard does not provide a method of acquiring engineering performance data since the stress distribution under flexural loading is indeterminate.
