ASME B5.8:2001(R2016)

Annotation of standard text ASME B5.8:2001(R2016) :

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 applies to chucks for use on engine lathes, tool room lathes, turret lathes, and automatic lathes and fit American Standard Spindle Noses of ANSI-B5.9-1967. They may be used on other applications for which they are suitable (see pages 4 and 5 of ANSI-B5.9-1967). It is within the scope of this Standard to establish: (a) duty classes; (b) standard chuck diameters; (c) top jaw interchangeability; (d) mounting interchangeability (USA-Standard Spindle Noses); (e) draw-bar interchangeability for power chucks; (f) identification code for body, master jaws, top jaws dimensions, where interchangeability of chucks may be involved; and (g) nomenclature.
