Railway applications - Batteries for auxiliary power supply systems
This European Standard specifies rechargeable lead acid and NiCd-batteries for 110 V voltage auxiliary power supply system for railway vehicles. This standard may be applied to other rolling stock types (e.g. light rail vehicles, tramways, metros…) if these are not in the scope of another specific standard. Others technologies like NiMh or Lithium are not covered by this standard at present. The standard focuses on: - the description of mechanical interfaces: dimensions of the cells or monobloc batteries, main terminals and preferred sizes of the mounting space of the battery systems for lead acid batteries, - the description of mechanical interfaces: dimensions of the trays and main terminals for NiCd batteries (as they have different characteristics depending on the technology), - description of electrical interfaces: capacity, voltage and charging characteristic. This standard restricts the variety of different types provided by EN 60254 and EN 60896 for lead acid batteries and defines the use of cells compliant to EN 60623 and EN 62259 for NiCd-Batteries. The main objective of this standard is to achieve interchangeability of the battery cells and monobloc for lead acid batteries and the interchangeability of the battery trays for NiCd batteries.

Low-voltage surge protective devices - Surge protective devices for specific application including d.c. - Part 11: Requirements and tests for SPDs in photovoltaic applications
This European Standard defines the requirements and tests for SPDs intended to be installed on the d.c. side of photovoltaic installations to protect against induced and direct lightning effects. These devices are connected to d.c. power circuits of photovoltaic generators, rated up to 1 500 V. It takes into account that photovoltaic generators: - behave like current generators, - that their nominal current depends on the light intensity, - that their short-circuit current is almost equal to the nominal current, - are connected in series and/or parallel combinations leading to a great variety of voltages, currents and powers from a few hundreds of W (in residential installations) to several MW (photovoltaic fields). The very specific electrical parameters of PV installations on the d.c. side require specific test requirements for SPDs. SPDs with separate input and output terminal(s) that contain a specific series impedance between these terminal(s) (so called two port SPDs according to IEC 61643-11) are currently not sufficiently covered by the requirements of this standard and require additional consideration. NOTE In general SPDs for PV applications do not contain a specific series impedance between the input/output terminals due to power efficiency considerations. SPDs complying with this standard are exclusively dedicated to be installed on the d.c. side of photovoltaic generators. PV installation including batteries and other d.c. applications are not taken into account and additional requirements and tests may be necessary for such applications. SPDs for which the manufacturers declares short circuit mode overload behaviour, shall require specific measures to ensure that such devices will not endanger the operator during maintenance and replacement due to possible d.c. arcing.

This International Standard is applicable to mechanical switching devices designed as "circuitbreakers for equipment" (CBE) for household and similar applications. CBEs according to this standard are intended to provide protection to circuits within electrical equipment including its components (e.g. motors, transformers, internal wiring). This standard covers also CBEs applicable for protection of electrical equipment in case of undervoltage and/or overvoltage. This standard also covers CBEs which are suitable for isolation. NOTE The term "equipment" includes appliances. CBEs are not applicable for overcurrent protection of wiring installations of buildings. CBEs according to this standard have: – a rated voltage not exceeding 440 V a.c. (between phases) and/or d.c. not exceeding 250 V; – a rated current not exceeding 125 A; – a short-circuit capacity (Icn) of at least 6xIn (a.c types) and 4xIn (d.c.-types) but not exceeding 3 000 A. CBEs may have a conditional short-circuit current rating in association with a specified shortcircuit protective device (SCPD). A guide for coordination of a CBE associated in the same circuit with a SCPD is given in Annex F. For CBEs having a degree of protection higher than IP20 according to IEC 60529, for use in locations where hazardous environmental conditions prevail (e.g. excessive humidity, heat or cold or deposition of dust) and in hazardous locations (e.g. where explosions are liable to occur), special constructions may be required. This standard contains all the requirements necessary to ensure compliance with the operational characteristics required for these devices by type tests. It also contains the details relative to test requirements and methods of testing necessary to ensure reproducibility of test results. This standard states: a) the characteristics of CBEs; b) the conditions with which CBEs shall comply, with reference to: 1) their operation and behaviour in normal service; 2) their operation and behaviour in case of overload; 3) their operation and behaviour in case of short-circuits up to their rated short-circuit capacity; 4) their dielectric properties; c) the tests intended for confirming that these conditions have been met and the methods to be adopted for the tests; d) the data to be marked on the devices; e) the test sequences to be carried out and the number of samples to be submitted for certification purposes (see Annex C); f) the routine tests to be carried out to reveal unacceptable variations in material or manufacture, likely to affect safety (see Annex J).

Superconductivity - Part 17: Electronic characteristic measurements - Local critical current density and its distribution in large-area superconducting films (IEC 61788-17:2013)
This part of IEC 61788 describes the measurements of the local critical current density (Jc) and its distribution in large-area high-temperature superconducting (HTS) films by an inductive method using third-harmonic voltages. The most important consideration for precise measurements is to determine Jc at liquid nitrogen temperatures by an electric-field criterion and obtain current-voltage characteristics from its frequency dependence. Although it is possible to measure Jc in applied DC magnetic fields [20, 21]2, the scope of this standard is limited to the measurement without DC magnetic fields. This technique intrinsically measures the critical sheet current that is the product of Jc and the film thickness d. The range and measurement resolution for Jcd of HTS films are as follows: - Jcd: from 200 A/m to 32 kA/m (based on results, not limitation); - Measurement resolution: 100 A/m (based on results, not limitation).

Air intake filter systems for rotary machinery - Test methods - Part 1: Static filter elements (ISO 29461-1:2013)
ISO 29461 specifies methods and procedures for determining the performance of particulate air filters used in air intake filter systems for rotary machinery such as stationary gas turbines, compressors and other stationary internal combustion engines. It applies to air filters having an initial particle efficiency up to 99,9 % with respect to 0,4 μm particles. Filters with higher initial particle efficiencies are tested and classified according to other standards (e.g. EN 1822). These procedures are intended for filters which operating at flow rates within the range 0,25 m3/s (900 m3/h) up to 1,67 m3/s (6000 m3/h). This part of ISO 29461 refers to static (barrier) filter systems but can be applied to other filter types and systems in appropriate circumstances. Two methods of determining the efficiency are used in this part of ISO 29461: — particulate efficiency (measured with respect to particle number and size); — gravimetric efficiency (percentage weighted mass removal of loading dust. Also a flat sheet media sample or media pack sample from an identical filter is conditioned (discharged) to provide information about the intensity of the electrostatic removal mechanism. After determination of its initial particle efficiency, the untreated filter is loaded with dust in steps until its final test pressure drop is reached. Information on the loaded performance of the filter is then obtained. The performance results obtained in accordance with this part of ISO 29461 cannot be quantitatively applied (by themselves) to predict performance in service with regard to efficiency and lifetime. Other factors influencing performance to be taken into account are described in the annexes.

Railway applications - Fixed installations - Particular requirements for alternating current switchgear - Part 1: Circuit-breakers with nominal voltage above 1 kV
This EN 50152-1 is applicable to single-pole and two-pole alternating current (a.c.) circuit-breakers which are: - for indoor or outdoor fixed installations in tractions systems, and - operated with an a.c. line voltage and frequency as specified in EN 50163. NOTE 1 EN 50163 specifies the a.c. traction systems 15 kV 16,7 Hz and 25 kV 50 Hz. NOTE 2 As rails of a.c. traction systems are connected to earth and included in the return current path all phase to earth voltages will be within the tolerances as specified in EN 50163. Nevertheless phase to phase voltages are sometimes higher e.g. in autotransformer systems. This European Standard is also applicable to the operating devices of circuit-breakers and to their auxiliary equipment. This European Standard does not address circuit-breakers with dependent manual operating mechanism. NOTE 3 It is impossible to specify a rated short-circuit making current for these circuit-breakers and it is likely that such dependent manual operation is not meeting safety considerations.
