Petroleum, petrochemical and natural gas industries. Flexible couplings for mechanical power transmission. Special-purpose applications Ingestion-build-65808 This edition of the standard1 Scope This International Standard specifies the requirements for couplings for the transmission of power between the rotating shafts of two machines in special purpose applications in the petroleum, petrochemical and natural gas industries. Such applications are typically in large and or high speed machines, in services that can be required to operate continuously for extended periods, are often unspared and are critical to the continued operation
