| Published By | Publication Date | Number of Pages |
| BSI | 2020 | 145 |
This document applies to superabrasives products containing natural or synthetic diamond or cBN (cubic boron nitride). It includes precision grinding and cutting-off wheels, non-precision cutting-off wheels, diamond wires, mounted points and other superabrasive products for non-precision grinding. It also applies to reconditioned superabrasive cutting-off wheels.
This document specifies requirements and/or measures for the removal or reduction of hazards resulting from the design and application of the superabrasive products.
This document contains also procedures and tests for verification of the compliance with the requirements as well as safety information for use, which will be made available to the user by the manufacturer.
This document does not apply to bonded abrasive products, coated abrasive products, rotating dressing tools, truers or any non-rotating superabrasive products.
