What is BS EN 843-5 - Weibull distribution of monolithic ceramics about?

BS EN 843 is a European standard series that discusses advanced technical ceramics. BS EN 843-5 is the 5 th part on the mechanical properties of monolithic ceramics at room temperature. BS EN 843-5 specifies a method for statistical analysis of ceramic strength data in terms of a two-parameter Weibull distribution using a maximum likelihood estimation technique. BS EN 843-5 assumes that the data set has been obtained from a series of tests under nominally identical conditions. Note 1: In principle, Weibull analysis is considered to be strictly valid for the case of linear elastic fracture behaviour to the point of failure, i.e., for perfectly brittle material, and under conditions in which strength limiting flaws do not interact and in which there is only a single strength-limiting flaw population. Note 2: BS EN 843-5 does not provide a method for dealing with censored data. Note 3: If subcritical crack growth or creep deformation preceding fracture occurs, Weibull analysis can still be applied if the results fit a Weibull distribution, but numerical parameters may change depending on the magnitude of these effects.
