IEC 61169-70:2024, which is a sectional specification (SS), provides information and rules for the preparation of detail specifications (DS) of HD-BNC series RF coaxial connectors together with the pro forma blank detail specification. HD-BNC series connectors with characteristic impedance of 75 Ω are used with RF cables or micro-strips in microwave, telecommunication, wireless and other fields. The operating frequency limit is up to 18 GHz. It also prescribes mating face dimensions for general purpose connectors, gauging information and tests selected from IEC 61169-1, applicable to all detail specifications relating to series HD-BNC RF connectors. This specification indicates the recommended performance characteristics to be considered when writing a detail specification and it covers test schedules and inspection requirements for assessment levels M and H.

This part of IEC 60512, when required by the detail specification, is to be used for testing connectors within the scope of IEC technical committee 48. This test may also be used for similar components when specified in a detail specification. The object of this test is to define a standard test method to assess the solderability of the terminations of a component designed for use with printed boards or for other applications using similar soldering techniques.

This part of IEC 60512 is intended to be used as a basic specification. It contains basic test methods and procedures which, when required by the detail specification, are used for testing connectors within the scope of technical committee 48. They may also be used for similar devices when specified in a detail specification. The object of this standard is to establish test methods and measurement procedures for use in specifications for connectors. This standard is to be used in conjunction with the generic, sectional and detail specification which will select and prescribe the tests to be used, the required degree of severity for each of them and the permissible performance limits. The detail specification will also specify the deviations in procedure, which may be inevitable when applying a test to the type of component under consideration, and it will further specify any special procedures which may be required. In the event of conflict between this basic specification and any individual component specification, the requirements of the component specification will apply. NOTE 1 RF connectors will not be dealt with by this technical committee as they will be covered by technical committee 46, together with r.f. cables. NOTE 2 Sockets for components such as crystals or electronic tubes will be considered in co-operation with the relevant technical committee. NOTE 3 Safety requirements for switches will not be developed by this technical committee as they are covered by subcommittee 23J.

IEEE Std 1500 has developed a standard design-for-testability method for integrated circuits (ICs) containing embedded nonmergeable cores. This method is independent of the underlying functionality of the IC or its individual embedded cores. The method creates the necessary requirements for the test of such ICs, while allowing for ease of interoperability of cores that may have originated from different sources.
