scope:

This Standard specifies the single mode and two population parameter Weibull statistics which is a method for determining the shape parameter (Weibull coefficient) and scale parameter of the instant break strength data obtained from the bending strength test and tensile strength test of fine ceramics at room temperature and elevated temperature.

NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 20501 : 2003 Fine ceramics (advanced ceramics, advanced technical ceramics)-Weibull statistics for strength data (MOD)

The symbols which denote the degree of correspondence in the contents in the corresponding International Standard and JIS are IDT (identical), MOD (modified) and NEQ (not equivalent) according to ISO/IEC Guide 21-1.
