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.

This International Standard 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.
The current noise in resistive materials reflects the granular structure of the resistive material.
For some resistor technologies utilizing homogenous layers it is regarded as providing an
indication of defects, which are considered as a root cause for abnormal ageing of the
component under the influence of temperature and time.
The method described in this International Standard is not a general specification requirement
and therefore is applied if prescribed by a relevant component specification, or, if agreed
between a customer and a manufacturer.

A blank detail specification is a supplementary document to the sectional specification and contains
requirements for style and layout and minimum content of detail specifications. Detail specifications not
complying with these requirements should not be considered as being in accordance with European
Standards nor should they be so described.
In the preparation of the detail specification the content of EN 60115-8:2012, 1.4 should be taken into
account.
The detail specification should be written by using the preferred values given in EN 60115-8.
The detail specification should contain a table of contents prior the first page of the actual specification.
For the use of SI units refer to EN ISO 80000-1, for the use of letter symbols to be used in electrical

IEC 61755-2-5:2015 defines a set of prescribed conditions that should be maintained in order to satisfy the requirements of angled polished reference connections. The prescribed conditions include dimensional limits and optical fibre requirements of the optical interface to meet specific requirements for reference connection (plugs and adaptors) used for attenuation measurements. Two different grades for reference connections are defined in this standard. The use of each of these grades depends on the application and on the targeted attenuation measurement uncertainty. The model uses a Gaussian distribution of light intensity over the specified restricted mode field diameter (MFD) range. This standard is intended to be used for shipping and acceptance inspections. The reference connector plug is specified for B1.1, B1.3 and B6 fibres as specified in IEC 60793-2-50. The use of the reference connector plug would not be recommended where classification of fibre is difficult, for example construction and maintenance of cable plant.

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.

IEC 60695-10-2:2014 specifies the ball pressure test as a method for evaluating the softening temperature and accelerated material flow under load of polymeric materials and parts of end products in their ability to resist abnormal heat. It is applicable to the materials used in electrotechnical equipment, subassemblies and components, and to solid electrical insulating materials except ceramics. The Ball Pressure test method is not appropriate for certain elastomers, foamed materials, and other materials that tend to be soft at room temperature. Product Committees are encouraged to evaluate these materials using other methods such as IEC 60695-10-3. This third edition cancels and replaces the second edition of IEC 60695-10-2 published in 2003. It constitutes a technical revision. The main changes with respect to the previous edition are as follows:
- The addition of an introduction introduces the user to the basic guidance documents published by TC 89,
- Addition of a reference to IEC Guide 104 and ISO/IEC Guide 51 in the Scope,
- Additional relevant Terms and Definitions in new Clause 3,
- 5.2: Additional requirements to the test specimen support at the suggestion of IECEE-CTL to improve reproducibility,
- 5.3: Clarification of heating oven requirements at the suggestion of IECEE-CTL to improve reproducibility,
- 5.4: Specification of minimum resolution consistent with method requirements for optical measurement instrument,
- New Test Procedure in Clauses 6 and 8 which introduces separate methods for End Product proof testing (Method A) and material performance testing (Method B) and
- Updated Clause 11 Test Report to be consistent with other IEC 60695 documents.
