This International Standard is applicable to inductive components (chokes and transformers) based on magnetically soft materials. These are especially components based on laminated iron sheets, iron powder materials (including alloys), as well as ferrites and amorphous or crystalline metal band cores. Winding assemblies means wire winding assemblies as well as multilayer and stacking technologies of planar technology including the coil based on non-magnetic materials. Discrete type components and the different types of surface-mountable inductive components (SMD) are also consideredin this standard. The reliability of assemblies of inductive components based on several technologies such as glued types, types with clamps (clips), impregnated (varnished) types as well as (vacuum) potted types can also be checked with this reliability. The subsequent determinations can be applied either for the primary qualification of inductive components or for all ways of requalification examinations (design, process, change of production facility). They can also be applied for the monitoring of products out of actual manufacturing processes. This standard sets up a broad basis of electric and mechanical criteria of failure test procedures. If manufacturers advertise compliance with this standard in their data sheets, customers may request data to demonstrate compliance to this standard. The customers may also request the product to be in compliance to this standard by a recognised national institute.
