Title:Marine Push-Pull Control Cables
Issuing Committee:Marine Technical Steering Committee
Scope:This SAE Standard covers dimensions and nomenclature of a push-pull control cable used in inboard marine engine applications. The dimensions are representative of existing design practice prevalent in the industry. The flexible push-pull cable is a common motion transfer device for the remote operation of the throttle and clutch levers (hydraulically applied clutches) on marine propulsion units. Satisfactory function of remote controls depend upon observing the limitations of this cable and providing adequate connection to the propulsion unit. This standard, therefore, establishes nomenclature, dimensions, and installation recommendations for marine push-pull control cables.【英文标准名称】:StandardGuideforUseofSpectralSearchingbyCurveMatchingAlgorithmswithDataRecordedUsingMid-InfraredSpectroscopy
