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.

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.

Acoustics - Test code for the measurement of airborne noise emitted by rotating electrical machines (ISO/FDIS 1680:2013)
This International Standard specifies all the information necessary to carry out efficiently and under standardized conditions the determination, declaration, and verification of the noise emission characteristics of rotating electrical machines. It specifies noise measurement methods that can be used, and specifies the operating and mounting conditions required for the test. Noise emission characteristics include the sound power level and emission sound pressure level. The determination of these quantities is necessary: — for comparing the noise emitted by machines; — to enable manufacturers to declare the noise emitted; and — for the purposes of noise control. The use of this International Standard as a noise test code ensures the reproducibility of the determination of the noise emission characteristics within specified limits determined by the grade of accuracy of the basic noise measurement method used. Noise measurement methods allowed by this International Standard are precision methods (grade 1), engineering methods (grade 2) and survey methods (grade 3). Methods of engineering grade (grade 2) are to be preferred. This International Standard is applicable to rotating electrical machines of any length, width or height.
