JIS R1621-2008《精细陶磁的室温弯曲疲劳试验方法》

This Standard specifies a testing method for four-point bending fatigue of fine
ceramics that are carried out in the air at room temperature (5 ℃ to 35 ℃).
NOTE : The International Standard corresponding to this Standard is as follows.
ISO 22214:2006 Fine ceramics (advanced ceramics, advanced technical
ceramics)--Test method for cyclic bending fatigue of monolithic ceramics
at room temperature (MOD)
In addition, symbols which denote the degree of correspondence in the
contents between the relevant International Standard and JIS are IDT
(identical), MOD (modified), and NEQ (not equivalent) according to ISO/
IEC Guide 21.
