European foreword
This document (EN 1279-3:2018) has been prepared by Technical Committee CEN/TC 129 “Glass in
building”, the secretariat of which is held by NBN.
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 January 2019 and conflicting national standards shall
be withdrawn at the latest by January 2019.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 1279-3:2002.
The main changes compared to the previous edition EN 1279-3:2002 are:
a) the standard has been fully technically and editorially revised;
b) the scope has been changed;
c) Terms and definitions and symbols have been split into two clauses;
d) requirement for gas leakage rate has been significantly changed;
e) the test method of this standard is also applicable to triple glazing units;
f) gas leakage rate can be determined after ageing a minimum two and a maximum four test
specimens. Durability of gas and interaction with IGU components has been added to requirements;
g) precision of the test method has been moved to A.4.8 and updated following a new inter-laboratory
test performed in 2009;
h) "Test report" has been revised adding a full description of the test specimen;
i) “Requirements for other gases” has been changed and moved to EN 1279-5:2018, Annex B: “Effect
