This Standard is a revision of the ASME Standard B29.100-2002 Precision Power Transmission, Double-Pitch Power Transmission, and Double-Pitch Conveyor Roller Chains, Attachments, and Sprockets, achieved by consolidation of two of its three constituent Standards: ASME B29.3 Double-Pitch Power Transmission Roller Chains and Sprockets and ASME B29.4 Double-Pitch Conveyor Roller Chains, Attachments, and Sprockets. (The third constituent Standard B29.1 Precision Power Transmission Roller Chains, Attachments and Sprockets was earlier revised and published as a separate Standard B29.1-2011 with its title unchanged). No changes were made to dimensional limits or capacities formerly listed in B29.3M and B29.4M; however, some text and several Tables were merged to eliminate redundancies.
