This part of this European Standard 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 should only be 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 accordance with 5.1.2. Where several inserts are installed, they should be 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 should 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 (∆T_A∙K) should not exceed the temperature increase of the tested data cabinet (∆T_B∙K) in which the diskette insert has been type-tested by more than the difference between the maximum value for the diskette insert (∆T_i∙K) and the maximum admissible temperature increase (30 K), i.e ∆T_A- ∆T_B≤30 K- ∆T_i (See example in Annex B).
A description of the installation of the diskette inserts should be given in the technical documentation of the manufacturer.

ISO/IEC 16963:2017 specifies an accelerated ageing test method for estimating the lifetime of the retrievability of information stored on recordable or rewritable optical disks. The method is based on the theoretical assumption that the lifetime of data recorded on an optical disk has a lognormal distribution. Detailed testing is specified for the following formats: DVD-R/RW/RAM disks, +R/+RW disks, CD-R/RW disks and BD recordable/rewritable disks. The testing can be applied to additional optical-disk formats with substitution of the appropriate specifications and can also be updated by the committee in the future as required. ISO/IEC 16963:2017 includes: - stress conditions: - Basic and Rigorous stress-conditions for testing and subsequent analysis using both the Eyring and Arrhenius methods; - ambient storage conditions in which the lifetime of data stored on optical disk is estimated: - a Controlled storage-condition, Temp = 25 °C and RH = 50 %, representing full-time air conditioning. The Eyring method is used to estimate the lifetime under this storage condition; - a Harsh storage-condition, Temp = 30 °C and RH = 80 %, representing the most severe conditions in which users handle and store optical disks. The Arrhenius method is used to estimate the lifetime under this storage condition; - a description of the evaluation system; - procedures for specimen preparation and data acquisition; - definitions and methods used in testing specific disk types; - analysis of test results to determine the lifetime of stored data; - a format for reporting the estimated lifetime of stored data. The methodology includes only the effects of temperature and relative humidity. It does not attempt to model degradation due to complex failure mechanism kinetics, nor does it test for exposure to light, corrosive gases, contaminants, handling, or variations in playback subsystems. Disks exposed to these additional sources of stress or higher levels of temperature and relative humidity are expected to experience shorter usable lifetime.

This International Standard establishes general principles for the care and handling of digital optical
discs during use. It addresses the issues of physical integrity of the medium necessary to preserve access
to the recorded data (information). This International Standard includes recommendations for handling
procedures to maximize the effective life of optical discs. Faulty handling, packing and transporting
techniques and methods often cause physical damage to the discs and to the content recorded thereon.
Extending the longevity of optical discs requires the identification of appropriate handling methods, as
well as well-developed and implemented training programs.
For the purposes of this International Standard, the term “optical disc” includes the families of compact
disc (CD), digital versatile disc (DVD), high definition digital versatile disc (HD DVD) and Blu-ray disc
(BD)1), and any hybrids of these families. The term “optical disc” also includes each type of disc within
a family, including injection moulded [read-only memory (ROM)], dye-layer [recordable (R)] and phase
change [rewritable (RW, RE), random access memory (RAM), and recordable (BD-R)] technologies.
While some of the recommendations in this International Standard (e.g. those for staff training) apply
specifically to large-scale or long term usage, the basics of all recommendations in this International
Standard are intended to be applied in circumstances where the desired result is long-term usage of the
medium whether archival, commercial or personal.
This International Standard does not cover magneto-optical (MO) discs, laser discs (LD) or glass discs.
At the time of writing, International Standards do not exist for HD DVD and Blu-ray discs. Nonetheless,
it is believed that the recommendations in this International Standard for care and handling can equally
apply to them. It is recognized that some of these requirements are not necessarily possible for the
individual user to achieve.
The following are within the scope of this International Standard:
— use and handling environments, including pollutants, temperature and humidity and light exposure;
— contamination concerns;
— inspection;
— cleaning and maintenance, including cleaning methods and frequency;
— transportation;
— disasters, including water, fire, construction and post-disaster procedures;
— staff training.
The quality of the data written on the disc is outside the scope of this International Standard. However,
a high quality result of the recording phase is important to the longevity of information. It is advisable
that a rigorous program of data integrity testing be implemented, as this forms an obligatory part of
all digital long-term storage. In addition, when keeping digital information for archival purposes, it is
advisable that a multiple copy/multiple location strategy be in place.

EN 1143-2 specifies requirements and tests methods for deposit systems, and classifies the systems according to their burglary resistance and their resistance to the theft of deposits. This European Standard comprises two types of deposit system: - night safes which provide depositing services for the customers of financial institutions without giving access to the content of the night safe. - deposit safes which enable the personnel of a company to place money or valuables in safe custody without giving access to the content of the deposit safe. The installation condition for deposit safe according to this standard is that the depositing functions are installed inside the premises of the company and are only disposable for the personnel of the company. Parts of a Deposit system are a receiving unit, an input unit and in some cases, a chute. The standard includes design requirements for deposit systems controlled by programmable controllers and for the software for these. Controller hardware testing is restricted to mechanical or electromechanical attacks of electric motors, sensors, coils and similar devices; but software testing as attempts to influence controller software or controller hardware is not part of this standard. Deposit systems may have devices for functions such as user identification and/or counting and registration of money. Tests of and requirements for classification of such functions are not included. This standard does not cover protection of persons using the deposit system or the prevention of fraud committed by operators of the deposit system.

This International Standard provides suggested guidelines for four temperature and humidity macro-environments for archives that contain a variety of recording media, based on the corresponding ISO storage standards for those media. Whenever possible, this International Standard recommends that users follow the storage environments in the ISO storage standards. This International Standard does not replace those ISO storage standards. In addition to environment recommendations, those standards also include other vital information pertinent to the long-term keeping of recording materials, such as inspection, housing, and handling guidelines. Although microenvironments within a storage enclosure can be dependent upon the macro-environment, they are not the focus of this International Standard. The storage of traditional paper collections is not within the scope of this International Standard. However, many archives containing mixed recording media also include such collections. Archivists are encouraged to review the appropriate standards (see References and for those materials. Nitrate-base photographic films are also included in this International Standard, since they are often stored together with other materials.

This part of IEC 60950 specifies requirements for information technology equipment (ITE) with self contained data storage systems that contain hazardous moving parts. These data storage systems are typically large enough to permit a person to enter completely, however, the systems also include similar large equipment permitting complete limb or head access to the area containing hazardous moving parts. These requirements are additional to the relevant requirements in IEC 60950-1. The maximum three dimensional reach of a cartridge accessory assembly typically has a minimum motion envelop of 0,75 m3 or more. The equipments shall be installed in a RESTRICTED ACCESS LOCATION, such as a data centre. The exceptions for 2.1.3 and 4.5.4 noted in 1.2.7.3 of IEC 60950-1 do not apply to this Part 23. This standard is not applicable to equipment with non-self-contained hazardous moving parts, such as robotic equipment installed in an industrial environment.
