This Part of IEC 63093 specifies the shapes and dimensions of ferrite cores for inductive components (transformers and chokes) of which the coil is typically constructed by multi-layer board or the coil is part of the motherboard and the effective parameter values to be used in calculations. This part of IEC 63093 gives guidelines on allowable limits of surface irregularities applicable to planar cores as well.

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

The general consideration upon which the design of this range of cores is based is given in Annex A.

This part of IEC 63093 specifies the dimensions and allowable limits of surface irregularities of ferrite cores.

It is intended that this document will include ferrite cores which are widely used and referenced in industry, either because they are included in national standards, or because they are seen to have broad-based use in industry. Where applicable, it is intended that the existing industrial name for each standard part should appear with the part within this series.

It is intended that this standard will exclude ferrite cores which are specialty cores with limited use. Also, special cores which are only marginal variations upon standard cores are excluded.

A ferrite core produced by only one or two suppliers may generally be considered a specialty part, and not suitable as a standard core within this series. A ferrite core produced by three or more competing manufacturers may generally be considered to be a candidate to be included in this series.

IEC publishes electrical standards for families of ferrite cores, as well as this series of dimensional standards for families of ferrite cores. Modifications to the ferrite cores listed in one type of standard should be reflected in the other type.

This document should be considered as a general specification useful in the dialogue between ferrite core manufacturers and users about surface irregularities.

This International Standard specifies product specifications, requirements (security require- ments, component requirements, durability requirements, environmental and EMC requirements) and test methods for a digital door lock that is a locking device installed at the external or internal entrance doors of a building construction, and in which its mechanical components including mechatronical trims and mechatronical lock cylinders. The digital door lock can be a stand-alone single entrance product or a part of an integrated access control system or home network system.
