This part of IEC 62271 specifies requirements for internal arc classification of metal-enclosed pole-mounted AC switchgear installations with rated voltages above 1 kV and up to and including 52 kV with service frequencies up to and including 60 Hz. This document is applicable to three-phase, two-phase and single-phase open terminal equipment. Enclosures may include fixed and removable components and may be filled with fluid (liquid or gas) to provide insulation.

NOTE For the use of this document high-voltage (IEC 60050-601:1985, 601-01-27) is the rated voltage above 1 000 V. However, medium voltage (IEC 60050-601:1985, 601-01-28) is commonly used for distribution systems with voltages above 1 kV and generally applied up to and including 52 kV; refer to [1] of the Bibliography.

This document does not preclude that other equipment may be included in the same enclosure. In such a case, any possible influence of that equipment on the switchgear and controlgear is to be taken into account.

This Standard specifies the general requirements for the qualification, procurement, storage and delivery of photovoltaic assemblies, solar cell assemblies, bare solar cells, coverglasses and protection diodes suitable for space applications.

This standard does not cover the particular qualification requirements for a specific mission.

This Standard primarily applies to qualification approval for photovoltaic assemblies, solar cell assemblies, bare solar cells, coverglasses and protection diodes, and to the procurement of these items.

This standard is limited to crystaline Silicon and single and multi-junction GaAs solar cells with a thickness of more than 50 mm and does not include thin film solar cell technologies and poly-crystaline solar cells.

This Standard does not cover the concentration technology, and especially the requirements related to the optical components of a concentrator (e.g. reflector and lens) and their verification (e.g. collimated light source).

This Standard does not apply to qualification of the solar array subsystem, solar panels, structure and solar array mechanisms.

This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.

Qualification is a process to confirm compliance with requirements that have been established with reference to foregoing characterization and engineering test programs. Guidelines for characterization and engineering tests and for relaxation of qualification tests due to similarity with earlier performed qualification are defined in the handbook ECSS-E-HB-20-08. Those clauses in this standard, for which the Handbook gives additional information, will refer to the Handbook.

This document:

a)     specifies minimum performance and durability and requirements for infill materials used in synthetic turf, and textile sports surfaces;

b)    describes how the performance of an infill is to be measured, and the results classified;

c)     specifies the physical and chemical properties of an infill that are to be declared in a manufacturer’s product declaration;

d)    specifies minimum production control tolerance to ensure consistency of infill materials between production batches;

e)     describes how reclaimed infill is to be tested to assess its suitability for reuse.

NOTE 1       The sports performance characteristics of a synthetic turf or textile sports surface are provided by the combined characteristics of the synthetic turf or textile surface, any infill within the playing surface pile and any shockpad. The selection of the correct permutations of each is complex and the responsibility of the sports surface designer.

NOTE 2       If infill materials migrate from a synthetic turf or textile sports surface into the surrounding natural environment, they become a source of contamination. To minimize the risk this occurring, guidance on how to prevent infill migration from the sports facility is given in CEN Technical Report PD CEN/TR 17519.

This document gives general guidance for the sampling and analysis of benzene in air by pumped sampling, thermal desorption and capillary gas chromatography.

This document is in accordance with the generic methodology selected as the basis of the European Union reference method for the determination of benzene in ambient air [1] for the purpose of comparison of measurement results with limit values with a one-year reference period.

This document is valid for the measurement of benzene in a concentration range of approximately 0,5 μg/m3 to 50 μg/m3. Air samples are typically collected over periods ranging from a few hours to 7 days.

The upper limit of the useful range is set by the sorptive capacity (the safe sampling volume) of the sorbent and by the linear dynamic range of the gas chromatograph column and detector or by the sample splitting capacity of the analytical instrumentation used. The lower limit of the useful range depends on the noise level of the detector and on blank levels of benzene and/or interfering artefacts on the sorbent. Artefacts are typically sub ng for graphitised carbon sorbents, but higher levels of aromatic hydrocarbons have been noted in other sorbents – e.g. porous polymers. The detection limit will be approximately 1/10 of the lower concentration range.

This document provides general guidance for the sampling of benzene using either a single sampler, which is changed manually after every exposure period, or a multi-sampler capable of storing and exposing multiple samples without user intervention.

This document specifies one method for the desalination by poultices of porous inorganic materials constituting cultural heritage. The desalination methodology can be applied to salt-loaded porous inorganic materials either affected by salt weathering and/or to allow conservation treatments incompatible with soluble salt(s) contamination, or to prevent salt damage where contamination is known to be present. In all cases the desalination aims to decrease salt content.

Furthermore, this document gives the fundamental requirements for the desalination operation and guidelines for the choice of the most appropriate poultice components according to the characteristics of the substrate and types/quantities of salt(s) present in order to optimize the desalination process.
