alkaline;

polymer electrolyte (including direct methanol fuel cellfuel cells)[1];

phosphoric acid;

molten carbonate;

solid oxide;

aqueous solution of salts.

Fuel cell moduleFuel cell modules can be provided with or without an enclosure and can be operated at significant pressurization levels or close to ambient pressure.

This standard deals with conditions that can yield hazardhazards to persons and cause damage outside the fuel cell modulefuel cell modules. Protection against damage inside the fuel cell modulefuel cell modules is not addressed in this standard, provided it does not lead to hazardhazards outside the module.

These requirements may be superseded by other standards for equipment containing fuel cell modulefuel cell modules as required for particular applications.

This standard does not cover fuel cellfuel cell road vehicle applications.

This standard is not intended to limit or inhibit technological advancement. An appliance employing materials or having forms of construction differing from those detailed in the requirements of this standard may be examined and tested according to the purpose of these requirements and, if found to be substantially equivalent, may be considered to comply with this standard.

The fuel cell modulefuel cell modules are components of final products. These products require evaluation to appropriate end-product safety requirements.

This part of IEC 61400 specifies requirements to ensure the engineering integrity of wind turbine blades as well as an appropriate level of operational safety throughout the design lifetime. It includes requirements for:

 

aerodynamic and structural design

material selection, evaluation and testing

manufacture (including associated quality management)

transportation, installation, operation and maintenance of the blades

 

The purpose of this standard is to provide a technical reference for designers, manufacturers, purchasers, operators, third party organizations and material suppliers, as well as to define requirements for certification.

 

With respect to certification, this standard provides the detailed basis for fulfilling the current requirements of IEC 61400-22 and, when available, the IECRE system, as well as other IEC standards relevant to wind turbine blades. When used for certification, the applicability of each portion of this document should be determined based on the extent of certification, and associated certification modules per IEC 61400-22 and/or the IECRE system.

 

The rotor blade is defined as all components integrated in the blade design, excluding removable bolts in the blade root connection and support structures for installation.

 

This standard is intended to be applied to rotor blades for all wind turbines. For rotor blades used on small wind turbines according to IEC 61400-2, the requirements in that document may be applied instead.

 

At the time this standard was written, most blades were produced for horizontal axis wind turbines. The blades were mostly made of fiber reinforced plastics. However, most principles given in this standard would be applicable to any rotor blade configuration, size and material.

 

This standard should be used together with the appropriate IEC and ISO standards mentioned in Section 2.

This part of IEC 61000 is applicable to the immunity requirements of electrical and electronic equipment to radiated electromagnetic energy. It establishes test levels and the required test procedures.

The object of this standard is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to radiated, radio-frequency electro­magnetic fields. The test method documented in this part of IEC 61000 describes a consistent method to assess the immunity of an equipment or system against RF electromagnetic fields from RF sources not in close proximity to the EUT. The test environment is specified in clause 6.

NOTE 1 As described in IEC Guide 107, this is a basic EMC publication for use by product committees of the IEC. As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity test standard should be applied or not, and if applied, they are responsible for determining the appropriate test levels and performance criteria. TC 77 and its sub-committees are prepared to co-operate with product committees in the evaluation of the value of particular immunity tests for their products.

 

NOTE 2: Immunity testing against RF sources in close proximity to the EUT is defined in IEC 61000-4-39.

Particular considerations are devoted to the protection against radio-frequency emissions from digital radiotelephones and other RF emitting devices.

NOTE Test methods are defined in this part for evaluating the effect that electro­magnetic radiation has on the equipment concerned. The simulation and measurement of electromagnetic radiation is not adequately exact for quantitative determination of effects. The test methods defined in this basic standard have the primary objective of establishing an adequate reproducibility of testing configuration and repeatability of test results at various test facilities.

This standard is an independent test method. Other test methods may not be used as substitutes for claiming compliance with this standard.

This standard specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of EFD-cores, the essential dimensions of coil formers to be used with them, and the effective parameter values to be used in calculations involving them. It also gives guidance on allowable limits of surface irregularities applicable to EFD–cores in accordance with the relevant generic specification.

The selection of core sizes for this standard is based on the philosophy of including those sizes which are industrial standards, either by inclusion in national standards, or by broad-based use in industry.

This standard is considered as a sectional specification useful in the negotiation between ferrite core manufacturers and users about surface irregularities.

 The general considerations that the design of this range of cores is based upon are given in Annex A.

This part of IEC 60118 specifies methods for measurement of the bone conduction hearing aids characteristics.

The methods described will produce a suitable basis for the exchange of information or for direct comparison of the electroacoustical characteristics of bone conduction hearing aids. These methods are chosen to be practical and reproducible and are based on selected fixed parameters.

The results obtained by the methods specified in this standard express the performance under the conditions of the measurement but will not necessarily agree exactly with the performance of the hearing aid under practical conditions of use.

This document defines methods of measurement of characteristics of bone conduction hearing aids both:

transcutaneously coupled devices measured on a mechanical coupler, meeting requirements of IEC 60318-6,

bone coupled/bone anchored devices measured on a mechanical coupler configured as a skull simulator.

NOTE 1 A skull simulator is a mechanical coupler designed to present a specific mechanical impedance to a vibrator coupled with a mechanical coupling

Though the number of measurements covered by this part of IEC 60118 is limited, it is not intended that all measurements described herein are mandatory.

NOTE 2 Throughout this document all sound pressure levels specified are referred to 20 µPa. When appropriate, sound pressure level will be abbreviated to SPL.

This part of IEC 62271 applies to high-voltage alternating current disconnecting circuit-breakers for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 52 kV.

This standard identifies which requirements of IEC 62271-1, IEC 62271-100 and IEC 62271-102 standards are applicable. It also gives the additional requirements specific to these devices.

This standard covers single switching devices which perform the functions of both a circuit-breaker and a disconnector by means of contacts housed in a single enclosure, and in which the circuit-breaker contacts in the open position satisfy, or contribute to, the isolating requirements of the disconnector function. As there is interaction between the requirements of the separate functions it is necessary to consider the standardisation of requirements. This standard details the requirements for a disconnecting circuit-breaker, identifying where these differ from the separate requirements of a discrete circuit-breaker and a disconnector.

NOTE For design examples of disconnecting circuit-breakers, refer to Annex A.
