IEC Standards

This part of IEC 60424 gives guidelines on the allowable limits of surface irregularities of ferrite cores. This standard should be considered as a general specification useful in the dialogue between ferrite core manufacturers and customers about surface rregularities.

This part of IEC 60404 is intended to classify commercially available magnetic materials. The term “magnetic materials” denotes substances where the application requires the existence of ferromagnetic or ferrimagnetic properties.

This part of IEC 60245 details the particular specifications for rubber insulated and braided cords and for rubber insulated and rubber or polychloroprene or other equivalent synthetic elastomer sheathed cords and flexible cables of rated voltages up to and including 450/750 V. All cables should comply with the appropriate requirements given in IEC 60245-1 and

This part of IEC 60122 specifies the methods of test and general requirements for quartz crystal units of assessed quality using either capability approval or qualification approval procedures.

This part of IEC 601 18 gives recommendations for the measurement of the performance characteristics of air conduction hearing aids based on a free field technique and measured with an acoustic coupler. This part of IEC 60118 is applicable to the measurement and evaluation of the electroacoustical characteristics of hearing aids， for example for type

This part of IEC 60092 specifies the requirements for electrical, mechanical and particular characteristics of insulating and sheathing materials intended for use in shipboard and fixed and mobile offshore unit power, control, instrumentation and telecommunication cables. The different insulating and sheathing materials have been divided into three categories as listed in Table 1.

This part of IEC 60086 is applicable to primary batteries which are based on standardised electrochemical systems. It specifies – the physical dimensions, – the discharge test conditions and discharge performance requirements.
