適用范圍：This part of ISO 8434 specifies general and dimensional requirements for the design and performance of37° flared connectors that are suitable for use with ferrous and non-ferrous tubes with outside diameters from6 mm to 50,8 mm, inclusive. These connectors are for use in fluid power and general applications within thelimits of pressure and temperature specified in this part of ISO 8434.They are intended for the connection of tubes and hose fittings to ports in accordance with ISO 6149-1,ISO 1179-1, ISO 9974-1 and ISO 11926-1. (See ISO 12151-5 for related hose fitting specification.)These connectors provide full-flow connections with metal-to-metal sealing in hydraulic systems operating tothe working pressures shown in Table 1. Because many factors influence the pressure at which a systemperforms satisfactorily, these values shall not be understood as guaranteed minimums. For every application,sufficient testing will need to be conducted and the results reviewed by both the user and manufacturer toensure that required performance levels 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 5.5.Both metric and inch tubing can be accommodated by changing the sleeve (see Figure 7). In the past, theseconnectors have been used predominantly with inch tubing. For new and future designs, the use of metrictubing is preferred.This part of ISO 8434 also specifies a performance and qualification test for 37° flared connectors.
