ASME B5 Committee on Machine Tools recognized the need for an industry standard on metric-dimensioned chucks This Standard was developed after reviewing currently available national and international standards, which were used as its foundation B5.60.1 and B5.60.4 were completed in November 1999 and submitted to ASME The standard titled, Workholding Chucks: Jaw Type Chucks, comprises six parts, with each covering a specific aspect of workholding chucks, as follows: ASME ASME ASME ASME ASME ASME B5.60.1: B5.60.2: B5.60.3: B5.60.4: B5.60.5: B5.60.6: ASME ASME ASME ASME ASME B5.60.1 B5.60.3
