This Technical Specification proposes simple, cheap, comparative tests in order to discriminate easily, in a panel of automotive flooded lead-acid batteries the most acceptable model for PV Individual Electrification Systems. « It could be particularly useful for project implementers to test in laboratories of developing countries, the capability of locally made car or truck batteries to be used for their project. Furthermore battery testing specifications usually need too costly and too much sophisticated test equipment to be applied in developing countries laboratories. The tests provided in this document allow to assess batteries performances according to the general specification of the project (see IEC 62257-2) and batteries associated with their Battery Management System (BMS) in a short time and with common technical means. They can be performed locally, as close as possible to the real site operating conditions. The document provides also regulations and installation conditions to be complied with in order to ensure the life and proper operation of the installations as well as the safety of people living in proximity to the installation. This document is not a type approval standard. It is a technical specification to be used as guidelines and does not replace any existing IEC standard on batteries.

This part of IEC 62257 specifies the general requirements for erection and operation of PV arrays in decentralized rural electrification systems. This technical specification contains requirements for ELV and LV PV arrays. Particular attention must be paid to voltage level, as this is important for safety reasons and has an influence on protective measures and on the skill and ability level of people operating the systems. For the sake of completeness, this technical specification gives requirements for d.c. voltages below and above 120 V. However for rural electrification projects it is strongly recommended to choose a voltage in the range of extra low voltage, taking into account the assumed skills of the operators, installers and users. Nevertheless, designers must be aware that decreasing the voltage means increasing the current and thus transferring voltage hazards to current risks (risk of fire, etc.). The following PV array configurations are considered (see Figure 5 to Figure 7): a) single string of modules; b) multi-string PV array; c) PV array divided into several sub-arrays. Direct current systems, and photovoltaic systems in particular, pose various hazards in addition to those derived from conventional a.c. power systems, for example the ability to produce and sustain electrical arcs with currents that are not much greater than normal operating currents. This technical specification addresses those safety requirements arising from the particular characteristics of photovoltaic systems. The aim is to provide safety and fire protection requirements for: ? uninformed persons, including owner(s)/occupier(s) and users of the premises where photovoltaic arrays are installed; ? informed workers (e.g. electricians) working on these systems; and ? emergency workers (for example fire fighters). For installation of PV arrays see IEC 60364-7-712.

This Technical Specification describes a conceptual model for multimedia e-publishing and e-book. The conceptual model is specified from the standardization point of view in order to clarify the functionality of e-publishing/e-book components and the relationships between them and to define e-publishing services. The model provides the key technology to be standardized in e-publishing environment. It should be noted that the modelling is not intended for actual implementation of a system or system components for e-publishing. The modelling is expected to be used as a reference for discussing and developing new standardization work on multimedia e-publishing and e-books and, therefore, to contribute to the expansion of the international and domestic markets for multimedia e-publishing and e-book. The model is given as an example of the models for the multimedia data creation, data structure, equipment/system structure and user-system interface defined in IEC 61998:1998.

The purpose this part of IEC 62257-9 is to specify the general requirements for the design and the implementation of microgrids used in decentralized rural electrification to ensure the safety of persons and property and their satisfactory operation according to the scheduled use. This part of IEC 62257-9 applies to microgrids for decentralized rural electrification purposes. The microgrids covered by this part of IEC 62257-9 are low voltage a.c., three-phase or single-phase, with rated capacity less than or equal to 100 kVA. They are powered by a single micropowerplant and do not include voltage transformation. The low-voltage levels covered under this part of IEC 62257-9 are the 230 V 1-Ø/400 V 3-Ø systems, 220 V 1-Ø/380 V 3-Ø, the 120 V 1-Ø/208 V 3-Ø, 60 Hz or 50 Hz systems. This part of IEC 62257-9 specifies microgrids made of overhead lines because of technical and economical reasons in the context of decentralized rural electrification. In particular cases, underground cables can be used. The requirements cover microgrids with radial architecture.

The purpose of this part of IEC 62257 is to specify the general requirements for the design and the implementation of the interface equipment within the user’s installation which connects to a microgrid or the generating part of a standalone system. This part of IEC 62257-9 applies to a simplified user's interfaces (distribution board) in electrical installations with maximum power of 500 VA in Decentralized Rural Electrification Systems (DRES). NOTE For installations above 500 VA in decentralized electrification systems, IEC 62257-5 applies. This part of IEC 62257-9 applies to an interface equipment within the user’s installation and which connects the user's installation to: • 230 V a.c. or 120 V a.c. microgrid, • the generating part – a.c. or d.c. - of a stand-alone installation. This equipment provides protection, isolation, and distribution functions.
