Secure storage units - Classification and methods of test for resistance to fire - Part 2: Data rooms and data container

This part of the European Standard EN 1047 specifies requirements for data rooms and data containers. It includes a method of test for the determination of the ability of data rooms and data containers to protect temperature and humidity sensitive data media (see 3.5) and hardware systems (see 3.6) from the effects of fire. A test method for measuring the resistance to mechanical stress (impact test) provided by data rooms type B and data containers is also specified.
Requirements are also specified for test specimens, the technical documentation of the test specimens, materials specimens, physical fittings, the correlation of test specimens with the technical documentation and the preparation for type testing as well as test procedures.
In addition, a scheme to classify data rooms and data containers from the test results is given (see Table 2).
As well as providing protection against fire, correctly installed data rooms and data containers offer protection against impacts caused by failure during fire of components and objects external to the data room or data container.
Data rooms and data containers having the same design, protection and construction features (type and thickness of construction and protective materials, rebate geometry, lockings, doors, etc.) will only be given the same protection classification as that of the test specimen if the tolerances are within the ranges specified in Table 1.
NOTE   This European Standard does not regulate the use of data rooms in the meaning of the building laws of the respective countries. In the construction of data rooms, the respective national requirements should be considered.

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of an identical text or by endorsement, at the latest by August 2013, and conflicting national standards shall be withdrawn at the latest by August 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document includes Amendment 1 approved by CEN on 10 December 2012. This document supersedes !EN 1047-2:2009". The start and finish of text introduced or altered by amendment is indicated in the text by tags !". Part 1 of this Standard has been published as:  EN 1047-1, Secure storage units — Classification and methods of test for resistance to fire — Part 1: Data cabinets and diskette inserts.

EN 1047-2:2009+A1:2013 (E) 4 Introduction The testing conditions given in this European Standard provide a basis for simulating fires to determine, in a reproducible way, the fire resistance of data rooms and data containers. The values for the maximum temperature increase in protection classes R60D and C60D specified in accordance with Table 2 in this European Standard relate to the relatively short time of high temperature exposure occurring during a fire test; in general, they are not experienced by data media and systems hardware stored in data rooms and data containers in the normal and correct way. EN 1363-1 establishes the general principles for determining the fire resistance of various elements of construction when subjected to standard fire exposure conditions. Alternative and additional procedures to meet special requirements are given in EN 1363-2. The development of the temperatures and the relative humidity in the interior of a data room and data container cannot be measured under the standard series

EN 1363. The sensitivity of media (see 3.5) and hardware systems (see 3.6) to temperature and humidity requires additional protection with regard to excessively high temperatures and relative humidity, proof of which cannot be furnished through type tests in accordance with the European Standards EN 1363-1 and EN 1363-2. This additional protection requires a series of product solutions, the performance of which is type tested and certified on the basis of the standard series EN 1047. EN 1047-1 covers the type testing of data cabinets as freestanding units. EN 1047-2 covers the type testing of data rooms and data containers. For wall, ceiling and floor elements type tested within the framework of this system test, proof of an additional protection can be furnished in accordance with the European Standards EN 1363-1 and EN 1363-2.

EN 1047-2:2009+A1:2013 (E) 5 1 Scope This part of the European Standard EN 1047 specifies requirements for data rooms and data containers. It includes a method of test for the determination of the ability of data rooms and data containers to protect temperature and humidity sensitive data media (see 3.5) and hardware systems (see 3.6) from the effects of fire. A test method for measuring the resistance to mechanical stress (impact test) provided by data rooms type B and data containers is also specified. Requirements are also specified for test specimens, the technical documentation of the test specimens, materials specimens, physical fittings, the correlation of test specimens with the technical documentation and the preparation for type testing as well as test procedures. In addition, a scheme to classify data rooms and data containers from the test results is given (see Table 2). As well as providing protection against fire, correctly installed data rooms and data containers offer protection against impacts caused by failure during fire of components and objects external to the data room or data container. Data rooms and data containers having the same design, protection and construction features (type and thickness of construction and protective materials, rebate geometry, lockings, doors, etc.) will only be given the same protection classification as that of the test specimen if the tolerances are within the ranges specified in Table 1. NOTE This European Standard does not regulate the use of data rooms in the meaning of the building laws of the respective countries. In the construction of data rooms, the respective national requirements should be considered. SIST EN 1047-2:2009+A1:2013
