What is BS EN 4814 - Aerospace flange couplings up to 21 000 kPa 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 4814 specifies the required characteristics, inspection and test methods, quality assurance, and procurement requirements for inch series, pipe couplings, swivel flanges, for temperature ranges from type II to type V according to ISO 6771, and nominal pressure up to 21000 kPa (classic D according to ISO 6771).
BS EN 4814 also specifies in addition to the requirements of this technical specification, the coupling assemblies shall be qualified in accordance with equipment or component specification requirement.
