Područje primjene nacrta:

This document specifies a method for the determination of subcritical crack growth parameters of advanced monolithic technical ceramics in the temperature range 15 °C to 30 °C by measuring the dependence of mean flexural strength on the rate of loading.
The method is based on strength test procedures described in EN 843 1.
The applicability of this method is limited by specific requirements for a low scatter of the initial strength of the test pieces and an upper limit of the stress load rate for the data points considered.
This document is not applicable to test pieces with artificially introduced flaws or cracks.
