标准范围
This part of ISO 8434 specifies the general and dimensional requirements for 24° cone connectors usingcutting ring and O-ring seal cone (referred to as DKO) suitable for use with ferrous and non-ferrous tubes withoutside diameters from 4 mm to 42 mm inclusive. These connectors are for use in fluid power and generalapplications within the limits of pressure and temperature specified in this part of ISO 8434.They are intended for the connection of plain end tubes and hose fittings to ports in accordance withISO 6149-1, ISO 1179-1 and ISO 9974-1. (See ISO 12151-2 for related hose fitting specification.)These connectors provide full-flow connections in hydraulic systems operating to the working pressuresshown in Table 1. Because many factors influence the pressure at which a system performs satisfactorily,these values are not to be understood as guaranteed minimums. For every application, sufficient testing willneed to be conducted and reviewed by both the user and manufacturer to ensure that required performancelevels are met.NOTE 1 For new designs in hydraulic fluid power applications, see the requirements given in 9.6. Where therequirements of the application allow for the use of elastomeric seals, connector designs that conform to InternationalStandards and incorporate elastomeric sealing are preferred.NOTE 2 For use under conditions outside the pressure and/or temperature limits specified, see 5.4.This part of ISO 8434 also specifies a performance and qualification test for these connectors.
