Foreword
This Standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard uses the redraft law to modify and adopt ISO 11491:2017
"Implants for surgery - Determination of impact resistance of ceramic femoral
heads for hip joint prostheses".
The technical differences between this Standard and ISO 11491:2017 are as
follows:
- As for the normative references, this Standard has made adjustments with
technical differences, to adapt to the technical conditions of China. The
adjustments are mainly reflected in Clause 2 “Normative references”. The
specific adjustments are as follows:
 Replace ISO 4288 with GB/T 10610, which is identical to the
international standard;
 Replace ISO 197-1 with GB/T 11086, which modifies and adopts the
