ISO 6162-2:2018 and SAE J518-2:2017 code 62 is the same standard for hydraulic flanges with split clamps, one-piece clamps, flanged head, flange port.
Differences between ISO 6162-2 and SAE J518-2 as follows:
ISO 61 62-2:2018 standard is Flange connectors, ports and mounting surfaces for use at
a pressure of 42 MPa (420 bar), DN 13 to DN 76.
SAE J518-2:2017 standard is Hydraulic Flanged Tube, Pipe, and Hose Connections, 4-Screw Flange Connection 42 MPa (Code 62).
This ISO 61 62-2 gives general and dimensional specifications for flanged heads, split flange clamps (FCS and FCSM), one-piece flange clamps (FC and FCM), ports and mounting surfaces applicable to four screw, split and one-piece flange clamp type tube connectors and hose fittings for use at a pressure of 42 MPa (420 bar 1) ). It also specifies the dimensions of the seals to be used, as well as the grooves that house the seals.
This document also recognizes the need to accommodate metric screw fasteners (type 1) (for DN 13 to DN 76), as well as to provide a means to use existing inch screw fasteners (type 2) (for DN 13 to DN 51).
This SAE J518-2 Standard covers general and dimensional specifications for the Code 62 metric (type 1 ) and inch (type 2) flanged heads, flange clamps (FC and FCM), and split flange clamps (FCS and FCSM) applicable to four-screw flange type tube, pipe, and hose connections. Also included are the recommended port dimensions and port design considerations. Type 2 (inch) flange clamps and split flanges are not for new design.
The SAE flanged heads specified are incorporated into fittings having suitable means for attachment of tubes, pipes, or hoses to provide connection ends. These connections are intended for application in hydraulic systems, on industrial and commercial products, where it is desired to avoid the use of threaded connections.
The rated working pressure of an SAE Flange assembly shall not exceed the least of all the component working pressure rated values.
