Standards

In addition to the scope of IEC 61326-1 this part of IEC specifies more details test configurations operational conditions and performance criteria for equipment which is - use for testing measuring or monitoring of protective measure in low-voltage distribution systems and . - powered by battery and or from the circuit measured and portable.

In addition to the scope of International standard IEC 61326-1, this part specifies minimum requirements for immunity and emission regarding electromagnetic compatibility for in vitro diagnostic medical equipment equipment, taking into account the particularities and specific aspects of this electric equipment and their electromagnetic environment.

This part of IEC 61347 specifies particular safely requirements for electronic step-down convertors for use on d.c. supplies up to 250 V or a.c. supplies up to 1000 V at 50 Hz or 60 Hz and rated output voltage ~ 50 /2 unsmoothed d.c. between conductors or between any conductor and earth associated with tungsten- halogen lamps as specified in IEC 60357 and other filament lamps .

This part of IEC 61400 specifies essential design requirements to ensure the engineering integrity of wind turbines. Its purpose is to provides an appropriate level of protection against damage from all hazards during the planned lifetime.,

This part of IEC 61400 specifies a procedure for measuring the power performance characteristics of a single wind turbine and applies to the testing of wind turbines of all types and sizes connected to the electrical power network . In addition , this standard describes a procedure to be used to determine the power performance characteristics of small wind turbines (as defined in IEC 61400-2) when connected to either the electric power network or a battery bank . The procedure can be used for performance evaluation of specific turbines at specific locations, but equally the methodology can be used to make generic comparisons between different turbine models or different turbine settings.

This part of IEC 61400 deals with safety philosophy quality assurance and engineering integrity and specifies requirements for the safety of small wind turbines (SWTs) including design installation , maintenance and operation under specified external conditions. Its purpose is to provide the appropriate level of protection against damage from hazards from these systems during their planned lifetime.

This part of IEC 61400 presents measurement procedures that enable noise emissions of a wind turbine to be characterized. This involves using measurement methods appropriate to noise emission assessment at locations close to the machine , in order to avoid errors due to sound propagation , but far enough away to allow for the finite source size . The procedures described are different in some respects from those that would be facilitate characterization of wind turbine noise with respect to a range of wind speeds and directions. Standardisation of measurement procedures will also facilitate comparisons between different wind turbines.

This part of IEC 6 1400 includes - definition and specifications of the quantities to be determined for characterizing the power quality of a grid connected wind turbine. measurement procedures for qualifying the characteristics. procedures for assessing compliance with power quality requirements, including estimation of the power quality expected from the wind turbine type when deployed at a specific site, possibly in groups.

This technical specification provides guidelines for the full-scale structural of wind turbine blades and for the interpretation or evaluation of results as a possible part of a design verification of the integrity of the blade.

During the last few years , all major wind turbine manufacture have made desiccated efforts towards development adequate lighting protection systems, and the first experiences with these new designs are beginning to be seen . It is therefore reasonable at the this time to consider and prepare for a standardization effort that will give both manufactures and operators a common framework for appropriate lighting protection of wind turbines.
