European foreword
This document (EN 13616-1:2025) has been prepared by Technical Committee CEN/TC 393 “Equipment

This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by February 2026, and conflicting national standards shall
be withdrawn at the latest by February 2026.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights other than those identified above. CEN shall not be held responsible for identifying any or
all such patent rights.
This document supersedes EN 13616-1:2016.
a) Clause 2: Normative references were updated;
b) 3.2: The term “initial closure level” was replaced by “initial closure level for two stages closure device
only”;
c) 3.3: The term “final closure level” was replaced by “final closure level for single or two stages closure
final device”;
d) 3.9: New definition was added;
e) 4.2.1 and 4.2.3: Tolerance of ±5 % was added;
f) 5.2: Chemical suitability test was updated;
g) 5.3: Temperature range for final closure simulation was deleted;
h) New subclause 5.5: Subclause relating to pressure surge test was removed from previous subclause
on function test (5.6);
i) New Clause 6: Only FPC (Factory Production Control) aspects were kept according to previous
Clause 6 “AVCP”;
j) Figure B.1: Key was updated;
k) Table C.1: Maximum flow rate values were updated;
l) Annex ZA “Construction products Regulation - CPR” was deleted due to the fact that revision is not
candidate to the harmonization to CPR (but only to ATEX Directive).
An environmental check-list is indicated in the informative Annex D.
