Method of measurement of current noise generated in fixed resistors

IEC 60195:2016 specifies a method of measurement and associated test conditions to assess the "noisiness", or magnitude of current noise, generated in fixed resistors of any given type. The method applies to all classes of fixed resistors. The aim is to provide comparable results for the determination of the suitability of resistors for use in electronic circuits having critical noise requirements. This edition includes the following significant technical changes with respect to the previous edition:
- harmonization of the allocation of isolation resistors RM in the recommended operating conditions given in Table 2;
- correction of erroneous numeric values of the contribution of system noise, f(T - S) in Table 3;
- addition of advice on the prescription of requirements in a relevant component specification;
- addition of a set of recommended measuring conditions for specimens with a rated dissipation of less than 100 mW;
- complete editorial revision.

Fixed resistors for use in electronic equipment - Part 2: Sectional specification: Leaded fixed low power film resistors

IEC 60115-2:2014 is applicable to leaded fixed low-power film resistors for use in electronic equipment. These resistors are typically described according to types (different geometric shapes) and styles (different dimensions) and product technology. The resistive element of these resistors is typically protected by a conformal lacquer coating. These resistors have wire terminations and are primarily intended to be mounted on a circuit board in through-hole technique. The object of this standard is to prescribe preferred ratings and characteristics and to select from IEC 60115-1, the appropriate quality assessment procedures, tests and measuring methods and to give general performance requirements for this type of resistor. This edition includes the following significant technical changes with respect to the previous edition:
- it includes test conditions and requirements for lead-free soldering and assessment procedures meeting the requirements of a "zero defect" approach;
- it introduces a product classification based on application requirements;
- it includes an extension of the list of styles and dimensions;
- it includes the use of an extended scope of stability class definitions;
- it includes the extension of the lists of preferred values of ratings;
- it includes test conditions and requirements for lead-free soldering, for periodic overload and for resistance to electrostatic discharge (ESD);
- it includes a new set of severities for a shear test;
- it includes definitions for a test board;
- it includes the replacement of assessment level E and possible others by the sole assessment level EZ, meeting the requirements of a "zero defect" approach;
- it includes an extended endurance test, a flammability test, a temperature rise test, vibration tests, an extended rapid change of temperature test, and a single pulse high-voltage overload test;
- it includes requirements applicable to 0-ohm resistors (jumpers);
- it includes recommendations for the denomination, description, packaging and quality assessment of radial formed styles;
- it includes prescriptions for endurance testing at room temperature, supplementary to the rulings of IEC 60115-1.

Metallic communication cable test methods - Part 4-16: Electromagnetic compatibility (EMC) - Extension of the frequency range to higher frequencies for transfer impedance and to lower frequencies for screening attenuation measurements using the triaxial set-up

IEC 62153-4-16:2016(E) describes a method to extrapolate the test results of transfer impedance to higher frequencies and the test results of screening attenuation to lower frequencies when measured with the triaxial set-up according to IEC 62153-4-3 (method B) respectively IEC 62153-4-4. A similar approach to extrapolate the test results of transfer impedance to higher frequencies was already described in IEC 61196-1:1995 Subclause 12.2. This method is applicable for homogenous screens, i.e. screens having a transfer impedance directly proportional to length. The transfer impedance may have any frequency behaviour, i.e. it could have a behaviour where it does not increase with 20 dB per decade as observed for screens made of a foil and a braid.
