What is BS EN 4804 - 4 holes aerospace swivel flanges about?

The flange coupling is a driving coupling placed between rotating shafts. These shafts comprise a flange fixed on each shaft end, and are held and bolted together using a ring of bolts that complete the drive. These couplings are designed to seal two tube ends in a flush manner. BS EN 4804 specifies the characteristics of swivel flanges, 4 holes, for flange couplings in nickel alloy for inch series aerospace applications. BS EN 4804 determines the nominal pressure to be up to 21 000 kPa, depending on associated seal, tube material, tube diameter, and tube wall thickness in the assembly which can be seen in EN 4814
