Secure storage units - Classification and methods of test for resistance to fire - Part 1: Data cabinets and data inserts

This document specifies requirements for fire resisting data cabinets and diskette inserts.
Two methods of test are specified to determine the ability of fire resisting data cabinets to protect temperature and humidity sensitive contents from the effects of fire: a fire endurance test and a fire shock and impact test. Two levels of fire severity (S 60 and S 120) based upon time of fire exposure; and three protection classes (P, D and DIS) are specified using the maximum temperature increases and humidity values permitted within the storage space of the data cabinet.
Diskette inserts (DI 60 P/DIS and DI 120 P/DIS) are installed in data cabinets of protection class S 60 P or S 120 P, respectively, and subjected to a fire endurance test (see 5.1.2).
Requirements are also specified for test specimens, 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 fire resisting data cabinets and diskette inserts from the test results is also given (see Table 1).
Diskette inserts are only installed in data cabinets having the same design as the series of protection class S 60 P and S 120 P, respectively, in which the insert has been tested in using methods defined in 5.1.2. Where several inserts are installed, they are built in one beside the other or one above the other from bottom to top, respectively. The volume and total height of the installed inserts do not exceed 50 % of the total internal volume or 50 % of the internal height, respectively, of the data cabinets into which they are installed. The dimensions of the insert can be adapted by increasing the width and depth to the corresponding dimensions of the data cabinets. A reduction of these dimensions as well as a change of the height is only admitted within the specified tolerance.
The temperature increases during type-tests on data cabinets and diskette inserts will be considered in deciding the permitted diskette insert installations. For a permitted installation, the temperature increase of the intended data cabinet ( ) does not exceed the temperature increase of the tested data cabinet ( ) in which the diskette insert has been type-tested by more than the difference between the maximum value for the diskette insert ( ) and the maximum admissible temperature increase (30 K), i.e   (See example in Annex B).
A description of the installation of the diskette inserts can be given in the technical documentation of the manufacturer.

Wertbehältnisse - Klassifizierung und Methoden zur Prüfung des Widerstandes gegen Brand - Teil 1: Datensicherungsschränke und Disketteneinsätze

n Datensicherungsschränke und Disketten¬einsätze zum Schutz gegen Brände fest.
Zwei Prüfverfahren dienen der Ermittlung der Widerstandsfähigkeit von Datensicherungsschränken, temperatur- und feuchtigkeitsempfindliches Füllgut vor Brandeinwirkung zu schützen: eine Feuerwider-standsprüfung und eine Feuerstoß- und Sturzprüfung. Zwei Stufen der Beflammungsdauer (S 60 und S 120) und drei Güteklassen (P, D und DIS) sind vorgesehen, die unter Berücksichtigung der im Innenraum des Datensicherungsschrankes maximal zulässi¬gen Temperaturerhöhungen und Feuchtigkeits¬werte definiert werden.
Disketteneinsätze (DI 60 P/DIS und DI 120 P/DIS) werden in einem Datensicherungsschrank der Güteklasse S 60 P bzw. S 120 P eingebaut und einer Feuerwiderstandsprüfung unterzogen (siehe 5.1.2).
Außerdem sind Anforderungen für die Probekörper, die Technische Dokumentation des Probekörpers, die Übereinstimmung von Probekörper mit der Technischen Dokumentation, die Vorbereitung der Typprüfung sowie die Prüfverfahren definiert.
Ferner wird ein Schema zur Klassifizierung von vor Brandeinwirkung schützenden Datensicherungsschränken und Disketteneinsätzen nach ihrem Prüfergebnis gegeben (siehe Tabelle 1).
Disketteneinsätze sind nur in Datensicherungsschränke der baugleichen Serie der Güteklasse S 60 P bzw. S 120 P eingebaut werden, in der der Einsatz nach den Anforderungen nach 5.1.2 typgeprüft worden ist. Beim Einbau mehrerer Einsätze sind diese neben- bzw. übereinander von unten nach oben eingebaut werden. Das Volumen und die Höhe der eingebauten Einsätze darf 50 % des Gesamt-Innenvolumens bzw. 50 % der Innenhöhe der Daten¬sicherungsschränke, in die sie eingebaut werden, nicht überschreiten. Die Abmessungen des Einsatzes können durch Vergrößerung in der Breite und der Tiefe den entsprechenden Abmessungen der Datensicherungsschränke angepasst werden. Eine Verringerung dieser Abmessungen sowie eine Änderung der Höhe sind nur im Rahmen der festgelegten Toleranz zulässig.
Die Temperaturerhöhungen bei Typprüfungen der Datensicherungsschränke und Disketteneinsätze können bei der Entscheidung über die Einbaugenehmigung berücksichtigt werden. Die Temperaturerhöhung eines Daten¬sicherungsschrankes (ΔT_a∙ K), in den der Disketteneinsatz eingebaut werden soll, darf die Temperaturerhöhung des geprüften Datensicherungsschrankes (ΔT_b∙ K), in dem der Disketteneinsatz typgeprüft worden ist, um maximal den Wert überschreiten, den der Disketteneinsatz (ΔT_i∙ K) als Differenz zur maximal zulässigen Temperaturerhöhung (30 K) hatte, d. h. ΔT_a-ΔT_b≤30 K-ΔT_b (siehe Beispiel in Anhang B).
Der Einbau der Disketteneinsätze kann in der Technischen Dokumentation des Herstellers beschrieben werden.

Unités de stockage en lieu sûr - Classification et méthodes d'essai de résistance au feu - Partie 1 : Meubles de rangement fermés et cartouches à disquettes

Le présent document spécifie les exigences applicables aux meubles de rangement et cartouches à disquettes réfractaires.
Deux méthodes d’essai sont prescrites afin de déterminer l’aptitude des meubles de rangement réfractaires à protéger des contenus sensibles à la température et à l’humidité des effets d’un incendie : un essai d’endurance au feu et un essai de résistance aux chocs thermiques et aux impacts. La présente norme spécifie deux niveaux de gravité des incendies (S 60 et S 120) en fonction de la durée d’exposition au feu et trois classes de protection (P, D et DIS) établies à partir des augmentations de température maximales et des taux d’humidité admis à l’intérieur de l’espace de stockage du meuble de rangement fermé.
Les cartouches à disquettes (DI 60 P/DIS et DI 120 P/DIS) sont installées dans des meubles de rangement fermés d’une classe de protection S 60 P ou S 120 P, respectivement, et sont soumises à un essai d’endurance au feu (voir 5.1.2).
Les exigences s’appliquent également aux éprouvettes, à la documentation technique concernant les éprouvettes, à la corrélation entre l’éprouvette et la documentation technique, à la préparation de l’essai de type et aux modes opératoires d’essai.
Une classification des meubles de rangement fermés et des cartouches à disquettes en fonction des résultats d’essai est également fournie (voir Tableau 1).
Les cartouches à disquettes sont installées uniquement dans les meubles de rangement fermés présentant la même conception que celle de la série de classes de protection S 60 P et S 120 P, respectivement, pour laquelle la cartouche a été soumise à essai conformément aux méthodes définies au paragraphe 5.1.2. Lorsque plusieurs cartouches sont installées, celles-ci sont respectivement installées les unes à côté des autres ou les unes au-dessus des autres. Le volume et la hauteur totale des cartouches ainsi installées ne dépassent pas respectivement 50 % du volume interne total ou 50 % de la hauteur interne des meubles de rangement fermés de destination. Les dimensions de la cartouche peuvent être adaptées en modifiant sa largeur et sa profondeur en fonction des dimensions correspondantes des meubles de rangement fermés. Une réduction de ces dimensions de même qu’un changement de hauteur ne sont admis que dans les limites de la tolérance spécifiée.
Les augmentations de température observées au cours des essais de type sur les meubles de rangement fermés et les cartouches à disquettes seront prises en compte dans la détermination des installations de cartouches à disquettes autorisés. Dans le cadre d’un montage autorisé, l’augmentation de température du meuble de rangement fermé visé ( ) n’excède pas l’augmentation de température du meuble de rangement fermé soumis à essai ( ) dans lequel la cartouche à disquettes a subi un essai de type à hauteur d’une valeur supérieure à l’écart entre la valeur maximale établie pour la cartouche à disquettes ( ) et l’augmentation de température maximale admissible (30 K), soit   (voir exemple à l’Annexe B).
Le fabricant peut inclure dans sa documentation technique une description du montage des cartouches à disquettes.

Varnostne shranjevalne enote - Klasifikacija in metode preskušanja požarne odpornosti - 1. del: Omare za zaščito nosilcev podatkov in vložki za nosilce podatkov

Ta del evropskega standarda določa zahteve za omare za zaščito nosilcev podatkov in vložke za diskete, odporne proti požaru.
Opredeljeni sta dve metodi preskušanja, s katerima se določi zmožnost omar za zaščito nosilcev podatkov, odpornih proti požaru, glede zaščite vsebine, ki je občutljiva na temperaturo in vlago, pred ognjem: preskus odpornosti na ogenj in preskus požarnega udara. Na podlagi največjih dvigov temperature in vrednosti vlage, ki so dovoljene v prostoru za shranjevanje omare za zaščito nosilcev podatkov, sta določeni dve stopnji jakosti požara (S 60 in S 120) glede na čas izpostavljenosti ognju ter trije razredi zaščite (P, D in DIS).
Vložki za diskete (DI 60 P/DIS in DI 120 P/DIS) so nameščeni v omarah razreda zaščite S 60 P oziroma S 120 P in so preskušeni glede odpornosti na ogenj (glej točko 5.1.2).
Podane so tudi zahteve za preskusne vzorce, tehnično dokumentacijo vzorcev, razmerje med vzorci in tehnično dokumentacijo ter pripravo na tipsko preskušanje in preskusne postopke.
Poleg tega ta del podaja shemo za razvrstitev omar za zaščito nosilcev podatkov in vložkov za diskete, odpornih proti požaru, na podlagi rezultatov preskusa (glej preglednico 1).
Vložki za diskete naj se nameščajo samo v omare za zaščito nosilcev podatkov, ki imajo enako zasnovo kot serija z razredom zaščite S 60 P oziroma S 120 P, pri kateri je bil vložek preskušen v skladu s točko 5.1.2. Če je nameščenih več vložkov, naj bodo ti eden zraven drugega oziroma eden nad drugim od spodaj navzgor. Prostornina in skupna višina nameščenih vložkov naj ne presega 50 % skupne notranje prostornine oziroma 50 % notranje višine omar za zaščito nosilcev podatkov, v katerih so vložki nameščeni. Mere vložka je mogoče prilagoditi s povečanjem širine in globine, tako da ustrezata meram omare za zaščito nosilcev podatkov. Zmanjševanje teh mer in spreminjanje višine je dovoljeno le znotraj določene tolerance.
Dvigovanje temperature med preskušanjem tipov omar za zaščito nosilcev podatkov in vložkov za diskete bo upoštevano pri odločitvah glede dovoljene namestitve vložkov za diskete. Za dovoljeno namestitev naj dvig temperature predvidene omare za zaščito nosilcev podatkov (∆T_A K) ne presega dviga temperature preskušene omare za zaščito nosilcev podatkov (∆T_B K), v kateri je bil vložek za diskete tipko preskušen za več kot razliko med največjo vrednostjo vložka za diskete (∆T_i K) in največjim dovoljenim dvigom temperature (30 K), tj. ∆T_A – ∆T_B ≤ 30 K – ∆T_i (glej primer v dodatku B).
Namestitev vložkov za diskete naj bo opisana v tehnični dokumentaciji proizvajalca.

European foreword

This document (EN 1047-1:2019) 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 1047-1:2005.
Compared with EN 1047-1:2005, the following changes were made:

— type tests in the past have shown that testing intermediate heights in the fire endurance test do not

give a quality benefit. Therefore, this standard requires the test of the smallest and highest model

(see 5.1.1.1 and Annex C);

— for the fire shock and impact test the number of test specimens now is dependent on if a plinth is

used (see 3.5, 5.1.1.2.1, 5.1.1.2.2, 5.3 and 6.4.4);

— due to testing knowledge gained since the publication of the standard EN 1047-1 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 %;

— new clauses have been added to explain for which technical design ranges the results of the type tests

are usable, see 5.1, 5.2, Clause 9 and Annex C;

— a requirement on the material thickness of the test specimen compared to the technical

documentation has been added (5.3); photographic documentation shall include pictures from the

interior of the test specimen (6.4.4);
— references have been updated;
— the definition 3.3 has been made up-to-date;
— corrections have been made in Table 1;
— editorial changes have been made in 4.2, 5.2, 6.1 and 6.2.2.

This document, EN 1047 Secure storage units — Classification and methods of test for resistance to fire, is

composed of two parts:
— Part 1: Data cabinets and diskette inserts

Introduction

The testing conditions given in this document provide a basis for simulating fires to determine, in a

reproducible way, the fire resistance of data cabinets and diskette inserts in various protection classes.

The protection classes enable a comparison to be made of the resistance against fire provided by different

constructions.

The threshold values for the maximum temperature increases in the protection classes S 60 P/S 120 P

(150 K), S 60 D/S 120 D (50 K) and S 60 DIS/S 120 DIS (30 K) for data cabinets as well as DI 60 P/DIS

(30 K) and DI 120 P/DIS (30 K) for diskette inserts from a starting temperature of (21 ± 1) °C, and for the

maximum relative humidity (85 %) for the D and DIS protection classes, as defined in this document,

refer to the relatively short-term stress due to high temperatures during a fire test. They are not normally

experienced by data media stored in data cabinets and diskette inserts in the normal and correct way.

1 Scope

This document specifies requirements for fire resisting data cabinets and diskette inserts.

Two methods of test are specified to determine the ability of fire resisting data cabinets to protect

temperature and humidity sensitive contents from the effects of fire: a fire endurance test and a fire shock

and impact test. Two levels of fire severity (S 60 and S 120) based upon time of fire exposure; and three

protection classes (P, D and DIS) are specified using the maximum temperature increases and humidity

values permitted within the storage space of the data cabinet.

Diskette inserts (DI 60 P/DIS and DI 120 P/DIS) are installed in data cabinets of protection class S 60 P

or S 120 P, respectively, and subjected to a fire endurance test (see 5.1.2).

Requirements are also specified for test specimens, 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 fire resisting data cabinets and diskette inserts from the test results is also given

(see Table 1).

Diskette inserts are only installed in data cabinets having the same design as the series of protection class

S 60 P and S 120 P, respectively, in which the insert has been tested in using methods defined in 5.1.2.

Where several inserts are installed, they are built in one beside the other or one above the other from

bottom to top, respectively. The volume and total height of the installed inserts do not exceed 50 % of the

total internal volume or 50 % of the internal height, respectively, of the data cabinets into which they are

installed. The dimensions of the insert can be adapted by increasing the width and depth to the

corresponding dimensions of the data cabinets. A reduction of these dimensions as well as a change of

the height is only admitted within the specified tolerance.

The temperature increases during type-tests on data cabinets and diskette inserts will be considered in

deciding the permitted diskette insert installations. For a permitted installation, the temperature

) does not exceed the temperature increase of the tested
increase of the intended data cabinet (∆TK⋅

data cabinet (∆TK⋅ ) in which the diskette insert has been type-tested by more than the difference

between the maximum value for the diskette insert (∆TK⋅ ) and the maximum admissible temperature

increase (30 K), i.e. ∆T −≤ ∆T 30 KT−∆ (see example in Annex B).

A description of the installation of the diskette inserts can be given in the technical documentation of the

manufacturer.

account of the results of the relevant fire endurance test (see Clause 1).

The data cabinets of protection class S 60 P and S 120 P, respectively, and the diskette insert need to be

modified at their base for installing the measuring instrumentation. A fire shock and impact test is not

made.
5.2 Technical documentation

Detailed technical documentation (drawings, specifications of materials, installation and processing

advice) shall be submitted to the testing laboratory before the type test. The drawings shall give

specifications as to height, width and depth of the test specimens as well as the complete series including

materials and their thicknesses, dimensions of rabbet edges, boltwork, lock configuration, welds

including the method of their execution. The mass of the plinth shall be given if one of the test specimens

is supplied with a plinth.

Samples and detailed specifications of all heat protection materials and seals used in the test specimens

shall accompany the test specimens.

NOTE 1 With reference to all heat protection materials, the technical documentation can include: a) quality

control parameters, and b) details of the performance characteristics, or c) details of the constituent materials and

processing methods.

The date(s) on which the test specimens were filled with protection materials shall be given.

The envisaged protection class of the technical design range shall be given.

NOTE 2 In connection with the type test, the testing laboratory can mark three sets of the technical

documentation with signature, stamp and date. One set is sent to the applicant. One set is added to the monitoring

documentation for certification and quality assurance, and one set is kept in the testing files of the test laboratory.

5.3 Correlation of test specimen and technical documentation

Examine the correlation of the test specimens with the technical documentation before and after

commencing the type test. Establish that the dimensions, design, materials and type of construction of

the test specimens correspond to the technical documentation (see 5.2).

The wall and door thicknesses of the test specimen shall not exceed more than 3 % of the nominal

dimensions in the technical documentation.
6 Test methods
6.1 Principle

The fire endurance of the test specimens is assessed by heating and cooling in a furnace.

The performance of the test specimens against fire shock and impact is assessed by a heating/cooling

regime combined with a drop test.

During these type tests the temperature and, where appropriate, the relative humidity in the interior of

the test specimen is measured.
6.2 Test equipment

6.2.1 The furnace which shall be capable of providing the uniform heating and cooling conditions

specified in this standard, and constructed so that the four vertical walls of the test specimen can each be

exposed to the same heating conditions with no direct flame impingement onto the test specimen.

The distance between the interior walls of the furnace and the surface of the test specimen shall

be ≥ 750 mm. The furnace conditions shall conform to EN 1363-1. To meet these conditions, the setting

of the neutral pressure level shall be made in accordance with 6.2.2 and the measurement of the

temperature in the interior of the furnace shall be made with instrumentation in accordance with 6.2.3.

6.2.2 The furnace shall be operated such that the neutral pressure level is reached after approximately

5 min of firing, measured at 1 000 mm above the furnace base. Test specimens with a height

of > 1 000 mm shall be placed on the furnace base during the type test. Test specimens with a height

of ≤ 1 000 mm shall be positioned on a of a brick pedestal with a height of 500 mm. Pressure measuring

heads in accordance with EN 1363-1:2012, 4.5.2 shall be used.

In order to ensure consistent heating conditions, the width of the pedestal area around the projected

cross-sectional area of the test specimen should not exceed 200 mm.

6.2.3 Instrumentation for measuring the furnace temperature shall use thermocouples of type K (NiCr-

Ni) with an accuracy in accordance with EN 60584-1. They shall be mineral insulated in accordance with

EN 61515 with an outside diameter of 3 mm and with an uncovered measuring point of at least 25 mm.

6.2.4 Instrumentation for measuring the air and surface temperatures in the test specimen shall use

thermocouples consisting of 0,5 mm diameter wires of type K (NiCr-Ni) or type J (Fe-CuNi) with an

accuracy in accordance with EN 60584-1. The measurement results of test specimens of protection

class P shall be recorded at intervals not greater than 1 min, and of test specimens of protection class D,

DIS and P/DIS at intervals not greater than 5 min. The contact measurement points shall be in accordance

with EN 1363-1:2012, 4.5.1.2 and 4.5.1.4 respectively.

6.2.5 For the fire shock and impact test, irreversible thermal indicators, capable of measuring the

temperature with an error limit of max. 2 °C of the temperature value indicated shall be used.

NOTE Conventional temperature measuring devices are regarded as being impractical to use in the fire shock

and impact test because of potential damage due to the impact of the drop test. Devices other than irreversible

thermal indicators can be used if it can be shown that no loss of accuracy will occur.

6.2.6 Instrumentation for measuring air humidity inside the test specimen during the fire endurance

test in the range 45 % to 85 % relative air humidity, and capable of operating over the temperature range

---------------------- Page: 12 ----------------------
SIST EN 1047-1:2019
EN 1047-1:2019 (E)

20 °C to 75 °C with an error limit of max. 3 % of the indicated relative air humidity value. The relative air

humidity values shall be recorded at intervals not greater than 5 min.
6.2.7 Timing device, capable of running continuously throughout the test period.
6.2.8 Equipment for weighing test specimens, with an error limit of ±3 %.

6.2.9 Lifting equipment, capable of lifting the test specimen to the required height in the drop test.

6.2.10 Impact surface, bed of rounded pebbles 0,5 m thick, particle size (50 ± 15) mm, of a hard

(≥6 Mohs) mineral such as quartzite, granite, basalt or flint laid on a concrete base at least 300 mm thick.

The length and width of the impact surface shall be more than twice the width and depth of the test

specimen.

The testing laboratory should ensure that the bed of pebbles is not allowed to become too compacted by

repeated tests.
6.3 Preparation for test
6.3.1 Data cabinets

6.3.1.1 Suitably modify the base (see 6.3.1.5) of the test specimen for the fire endurance test (see

6.4.2) to allow the entry of thermocouple cables and humidity sensors. Plinths and other elements that

may prevent proper protection of the thermocouple cables may be removed.

Add lifting attachments (see A.2) to the test specimen for the fire shock and impact test (see 6.4.3). All

elements normally fitted below the cabinet body shall be retained for this test.

6.3.1.2 For the fire endurance test (see 6.4.2) install thermocouples (see 6.2.4) at the following points

in the test specimen to enable temperature measurement:

a) Four air temperature measuring points in the upper corners each (26,5 ± 1,5) mm from the walls,

interior door surface and ceiling (see points 1, 2, 3 and 4 of Figure 1).

b) One surface temperature measuring point on each of the ceiling, side walls, rear wall, and door,

approximately in the centre of each surface (see points 5, 6, 7, 8 and 9 of Figure 1).

c) For two-door cabinets only, two additional air temperature measuring points at (26,5 ± 1,5) mm

from the centre door joint, one (26,5 ± 1,5) mm from the ceiling and the other approximately half-

way up the cabinet (see points 10 and 11 of Figure 1).

d) For test specimens with several compartments (e.g. drawers), additional measuring points in each

compartment (drawer), as in a) and b).

6.3.1.3 For the fire shock and impact test (see 6.4.3) install thermal indicators (see 6.2.5) at the points

indicated in 6.3.1.2 a) and c) (see A.3).
