This Standard is drafted in accordance with the rules given in GB/T 1.1-2009. This Standard replaces YY 1137-2005 ?€?General technique requirements for orthopaedics saw?€?. As compared with YY 1137-2005, the main technical
changes are as follows.
- ADD YY/T 0294.1 and ASTM F899 standards for ?€?chemical composition?€?
(SEE 4.2), and EXPAND the range of materials used;
- MAKE corresponding adjustments to appearance (SEE 4.3) and
performance (SEE 4.4) requirements of the former standard;
- CHANGE the former standard?€?s Rockwell hardness to Vickers hardness
(SEE 4.5);
- ADD bending resistance (SEE 4.8 and Appendix A);
- DELETE the content of inspection rules (SEE Chapter 6 of YY 1137-2005). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. The issuing authority of this document shall not be held responsible for identifying any or all such patent rights.
