This sectional specification prescribes the characteristics, ratings and inspection requirements for magnetic cores of assessed quality. Such cored, intended for inductors and transformers in tuned circuits for professional and industrial applications, consist of at least two parts forming a substantially closed magnetic circuit.It selects from the generic specification CECC 25 000, the appropriate methods of test to be used in detail specificaions derived from this specification and contains the test schedules to be used in the preparation of such specifications. Each test schedule, referenced by a CECc number, when taken with the appropriate information in SECTION 5 of this specification, forms a blank detail specification.The cores covered by this specification may be used with an adjuster which provides for change of inductance for tuning.
