DIN EN 843-3-2005 高级工业陶瓷.室温下整体陶瓷的机械特征.第3部分:恒定应力速度挠曲强度试验中亚临界断裂增长参数的测定
Advanced technical ceramics - Mechanical properties of monolithic ceramics at room temperature - Part 3: Determination of subcritical crack growth parameters from constant stressing rate flexural strength tests; German version EN 843-3:2005
This European Standard specifies a method for the determination of subcritical crack growth parameters of advanced monolithic technical ceramics in the temperature range 15 ?to 30 ?by measuring the dependence of mean fracture strength on the rate of loading. The method is based on strength test procedures specified in EN 843-1. This European Standard is not applicable to test pieces with artificially introduced flaws or cracks.
