European foreword
This document (EN 15659:2019) has been prepared by Technical Committee CEN/TC 263 “Secure
storage of cash, valuables and data media”, the secretariat of which is held by BSI.
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 2020, and conflicting national standards shall
be withdrawn at the latest by February 2020.
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 15659:2009.
Compared with EN 15659:2009, the following changes were made:
— The protection levels were renamed from LFS 30 P and LFS 60 P to LFS 30 and LFS 60;
— that customers know the difference between this fire resistance standard and the fire resistance
standard EN 1047-1, the scope of the standard was adapted;
— as the standard could lead to different interpretations in different test houses regarding the choice
of test specimens a new Clause 5 and an Annex A have been added as well as Clause 6.1 has been
adapted;
— due to testing knowledge gained since the publication of the standard EN 15659 in 2009 it could be
seen that the depth is not as critical as the width of a specimen. Therefore, the tolerance on the depth
was changed from ± 15 % to ± 20 %;
— the fire exposure time now starts from the beginning of the test (7.4.2);
— the requirement for the 3 % wall tolerance has been updated in clause 5.1 (for series production)
and 6.2 (for the test specimens);
— a shrinking tube for the measuring device cables is not needed anymore (7.3.3), the testing
laboratory doesn't need to turn of the flames after 30 min or 60 min (7.4.2) and the photographic
record shall now also include details of the interior of the test specimen. (7.4.3);
— references to the standards have been updated;
— editorial changes have been made in 3.1, 3.2, 4.1, 4.2, 6.1, 6.2 and 7.4.1.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, 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 the United
Kingdom.
Introduction
The testing conditions given in this document provide a basis for simulating fires to determine, in a
reproducible way, the fire resistance of light fire storage units at various protection levels. The protection
levels enable a comparison to be made of the resistance against fire provided by different constructions.
The threshold value for the maximum temperature increase of 150 K at every measuring point in the
protection levels LFS 30 and LFS 60 for light fire storage units from a starting temperature of (21 ± 1)°C,
as defined in this document, refers to the relatively short-term stress due to high temperatures during a
fire test. It is not normally experienced by paper media stored in light fire storage units in the normal and
correct way.
1 Scope
This document specifies requirements for light fire storage units providing protection against fire.
The method of test is specified to determine the ability of light fire storage units to protect paper media
from the effects of fire. Two levels of fire exposure periods (LFS 30 and LFS 60) are specified using the
maximum temperature increase permitted within the storage space of the light fire storage unit.
Protection after the fire exposure of 30 min (LFS 30) or 60 min (LFS 60) is not ensured by this document,
but by European Standard EN 1047-1. Requirements are also specified for the test specimen, the technical
documentation for the test specimen, correlation of the test specimen with the technical documentation,
preparation for type testing and test procedures.
A scheme to classify the light fire storage units from the test results is also given (see Table 1).
