Overview
Portable socket-outlets according to this standard belong to the so-called "HNA installation material", the standardization of which was started by the "Commercial Ship Standards Committee" in the 1920s. They consist of housing with a screw cap to close the unused socket opening, in which a contact insert to DIN 89320 is mounted. They are used, for example, for the construction of cable extensions and can be used under harsh operating conditions, for example, outdoors and in the engine room of ships. Due to the asymmetrical contact arrangement, they can be used in DC and AC voltage systems. Two- and three-core cables can be connected, for example rubber sheathed cables according to DIN EN 50525-2-21 (VDE 0285-525-2-21). The plugs according to DIN 89267 fit into this portable socket-outlet. The "old" DIN 89267 from 1993 contains several invalid reference standards and obsolete material designations which have been corrected. Requirements and tests have been formulated more precisely in some cases. The present standard has been prepared by NA 132-03-52 AA "Installationsmaterial" ("Installation material") at DIN.
