    Abstract - (Show below) - (Hide below)

    Selects from the generic specification BS 9925-0, and from the basic specification BS 5938-1, the appropriate methods of test to be used in detail specifications for magnetic oxide cores intended for use in inductors and tuned transformers. Lists the ratings and characteristics and specifies the quality assessment procedures to be followed.
