IEC 62211 pdf download Inductive components – Reliability management
This International Standard is applicable to inductive components (chokes and transformers)based on magnetically soft materials. These are especially components based on laminatediron sheets,iron powder materials (including alloys), as well as ferrites and amorphous orcrystalline metal band cores.
Winding assemblies means wire winding assemblies as well as multilayer and stackingtechnologies 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 considered in this standard.
The reliability of assemblies of inductive components based on several technologies such asglued types, types with clamps (clips), impregnated (varnished) types as well as (vacuum)potted types can also be checked with this standard.
The subsequent determinations can be applied either for the primary qualification of inductivecomponents or for all ways of requalification examinations (design，process,change ofproduction facility). They can also be applied for the monitoring of products out of actualmanufacturing processes.
This standard sets up a broad basis of electric and mechanical criteria of failure testprocedures.
lf manufacturers advertise compliance with this standard in their data sheets,customers mayrequest data to demonstrate compliance to this standard.The customers may also request theproduct to be in compliance to this standard by a recognised national institute.
Customers and manufacturers may elect to perform additional testing and acceptance criteriadifferent than those defined in this standard.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
reliability of inductive components
component level reliability of the inductive component in the customers’ electrical circuit application
component level reliability tests
sequence of tests performed on an individual component, each specific test being designed to represent conditions under which the component is expected to operate in end applications NOTE Categories of test levels are organised to be consistent for typical applications.
system level reliability tests
sequence of tests performed on a collection of components as arranged in a specific end application under working conditions
group of components characterised by the same common features, for example the same magnetic base material, the same core size and the same winding type
