NF ISO 6162-2
Hydraulic fluid power - Flange connections with split or one-piece flange clamps and metric or inch screws - Part 2 : flange connectors, ports and mounting surfaces for use at a pressure of 42 MPa (420 bar), DN 13 to DN 76
ISO 6162-2:2012 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 ). It also specifies the dimensions of the seals to be used, as well as the grooves that house the seals. ISO 6162-2:2012 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). These connections are intended for application in hydraulic systems on industrial and commercial products where it is desired to avoid the use of threaded connectors. Surges of pressure higher than the nominal ratings will reduce the ability of the flange connections to retain the hydraulic fluid. This needs to be taken into account in the design of the hydraulic system.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
