52 - APPENDIX A - SPEED CONVERSION TABLE

Specifies requirements for the design and construction of abrasive wheels and the manufacture and installation of abrasive wheels and ancillary equipment. Particular requirements are given for the construction of guards for all equipment fitted with abrasive wheels and for the construction of flanges for use with abrasive wheels. Includes sections covering standard (normal) maximum operating speeds for all types of wheels. The Standard is extensively illustrated.

This standard sets out requirements for the design and construction of abrasive wheels (excluding natural sandstones) and includes requirements for safety guards, flanges, chucks, and revolving cups. Requirements for the proper storage, handling, and identification of abrasive wheels are also included. Application and operating requirements are included in AS 1788.2.
