New Standard from Last Update.

NATIONAL FOREWORD

‘This Indian Standard which is identical with ISO 20501 : 2019 ‘Fine ceramics (advanced ceramics, advanced technical ceramics) - Weibull statistics for strength data’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Ceramicware Sectional Committee and approval of the Division Council’.

This Indian Standard covers the reporting of uniaxial strength data and the estimation of probability distribution parameters for advanced ceramics which fail in a brittle fashion. The failure strength of advanced ceramics is treated as a continuous random variable. Typically, a number of test specimens with well-defined geometry are brought to failure under well-defined isothermal loading conditions. The load at which each specimen fails is recorded. The resulting failure stresses are used to obtain parameter estimates associated with the underlying population distribution.
