All relevant essential safety requirements of the European legislation for pressure equipment applicable to valves have been taken into consideration and are addressed in this standard.

The Annex ZA will be deleted from EN 593 and reference will be made to EN16668 Annex ZA, The Overview document provides more information about the content and has been prepared by Ron Strang and Martin Greenhalgh of BVAA.
