Die Annotation des Normtextes ASME B17.1:1967(R2017) :

This standard is being maintained under Stabilized Maintenance. Stabilized maintenance is an option for maintenance of a standard that requires status review every 10 years rather than revision or reaffirmation every 5 years. The Standards Committee shall consider all requests and recommendations for change to standards maintained under the stabilized maintenance option from any materially affected and interested party. The request shall be made in writing and should include the rationale for the particular request in order to facilitate review by the Committee.
This Standard establishes a uniform relationship between shaft size and key size for parallel and taper keys retaining similar basic sizing as found in the withdrawn B17.1-1943 Standard. This Standard covers the size, type and tolerances of parallel and taper keys and keyseats, and their relationship to shaft diameters and bore diameters. The sizes and tolerances contained in this Standard are intended for single key applications only. Key strength and steel analysis entering into the makeup of stock for keys is not within the scope of this Standard. Shaft diameters are listed for identification of various key sizes and are not intended to establish shaft dimensions, tolerances or selections.
