Safety Requirements for the Construction, Care, and Use of Grinding Machines
This standard applies only to grinding machines, designed primarily for metal removal, that present grinding tools against workpieces, producing change in shape, size, and surface finish by grinding. This standard also applies to these machines when they are grinding materials other than metals such as glass, ceramics, plastics, and rubber. This standard does not apply to portable hand held grinders, machines using loose abrasives, or machines used for concrete cutting on road construction jobs. Excluded from the requirements of this standard are: lens polishing machines; masonry cutting and grinding machines; tumbling machines; others primarily not designed for metal removal.
