What is BS EN IEC 63182-2about?
BS EN IEC 63182-2 is the second part in a multi-series that specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of ring-cores (also called toroid’s) made of magnetic powder, the effective parameter values to be used in calculations involving them and gives guidelines on allowable limits of surface irregularities applicable to coated ring-cores.
The selection of core sizes for BS EN IEC 63182-2 is based on the philosophy of including those sizes which are industry standards, meaning that they are in broad-based use within the industry. BS EN IEC 63182-2 is considered as a sectional specification useful in the negotiations between magnetic powder core manufacturers and users about surface irregularities.
