It is the UK implementation of EN 14620-4:2006. This standard, together with BS EN 14620-3:2006,supersedes BS 7777-3:1993 which is withdrawn.The UK participation in its preparation was entrusted to Technical CommitteePVE/15, Storage tanks for the petroleum industry. A list of organizations represented on PVE/15 can be obtained on request to itssecretary.This publication does not purport to include all the necessary provisions of acontract. Users are responsible for its correct application. Compliance with a British Standard cannot confer immunity fromlegal obligations.Amendments issued since publication  Amd.
