This European Standard was approved by CEN on 8 February 2019.
CEN members are bound to ply with the CEN/CENELEC Internal Regulations which stipulate the conditions for givingthis European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN-CENELEC Management Centreor to any CEN member.
This European Standard exists in three official versions (English French German). A version in any other language made by translation under the responsibility ofa CENmember into its own language and notified to the CEN-CENELECManagement Centre has the same status as the official versions.
CEN members are the national standards bodies of Austria elgium Bulgaria Croatia Cyprus Czech Republic Denmark Estonia Finland France Germany Greece Hungary Iceland Ireland Italy Latvia Lithuania Luxembourg Malta Netherlands Norway Poland Portugal Republic of North Macedonia Romania Serbia Slovakia Slovenia Spain Sweden Switzerland Turkey and United Kingdom.
