This part of IEC 60268 applies to transducers converting an electrical input signal into a
mechanical or acoustical output signal. However, if the electrical input terminals and the surface
of the radiator are accessible, this document can also apply to passive and active sound
systems such as loudspeakers, headphones, TV-sets, multi-media devices, personal portable
audio devices, automotive sound systems and professional equipment. This document
describes only electrical and mechanical measurements that help assess the transfer behaviour
of the device under test (DUT). This includes operating the DUT in both the small- and largesignal
domains. The influence of the target application's acoustical boundary conditions (e.g.
car interior) can also be considered in the physical evaluation of the sound system. Perception
and cognitive evaluations of the reproduced sound and the impact of perceived sound quality
are outside the scope of this document.
NOTE This document does not apply to microphones and other sensors. Implementation of this document does not
require access to the sound pressures generated in the near or far fields of the radiator. Directivity and other
characteristics describing the electro-acoustical transfer properties are described in IEC 60268-21, which covers
acoustical measurements.The practical application of the measurements for research and development (R&D), endof-
line testing (QC) and evaluation in the final target application (TA) is discussed in Annex A.

This document specifies basic framework measurement methods for sound immission from sound
sources placed close to the ear. These measurements are carried out with a manikin, equipped
with ear simulators including microphones. The measured values are subsequently converted into
corresponding free-field or diffuse-field levels. The results are given as free-field related or diffusefield
related equivalent continuous A-weighted sound pressure levels. The technique is denoted the
manikin technique.
This document is applicable to exposure to sound from sources close to the ear, for example during
equipment tests or at the workplace to sound from earphones or hearing protectors with audio
communication facilities.
This document is applicable in the frequency range from 20 Hz to 10 kHz. For frequencies above 10 kHz,
ISO 11904-1 can be used.

IEC 61966-12-1:2020 defines the colour gamut metadata scheme for video systems and similar applications. The metadata can be associated with wide-gamut video colour content or to a piece of equipment to display the content. When associated with content, the colour gamut metadata defines the gamut for which the content was created. It can be used by the display for controlled colour reproduction even if the display’s colour gamut is different from that of the content. When associated with a display, the colour gamut metadata defines the display colour gamut. It can be used during content creation to enable improved colour reproduction. The colour gamut metadata can cover associated colour encoding information, which includes all information required for a controlled colour reproduction, when such information is not provided by the colour encoding specification. The colour gamut metadata scheme provides scalable solutions. For example, more flexible solutions will be used for the professional use, while much simpler solutions will be used for consumer use with easier product implementation. This part of IEC 61966 only defines the colour gamut metadata scheme. Vendor-specific solutions for creation and end-use of this metadata are allowed.

IEC 61897:2020 is available as IEC 61897:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 61897:2020 applies to aeolian vibration dampers intended for single conductors or earth wires or conductor bundles where dampers are directly attached to each subconductor. The purchaser may adopt part(s) of this document when specifying requirements for cables different from those mentioned above (e.g. optical ground wires (OPGW), all dielectric self-supporting optical cables (ADSS)). In some cases, test procedures and test values are left to agreement between the purchaser and the supplier and are stated in the procurement contract. Annex A lists the minimum technical details to be agreed between purchaser and supplier. Throughout this document, the word “conductor” is used when the test applies to dampers for conductors or earth wires. This second edition cancels and replaces the first edition published in 1998. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) Consider, in addition to Stockbridge type aeolian vibration dampers, also spiral aeolian vibration dampers and elastomeric aeolian vibration dampers.
b) Consider the application of dampers on high temperature conductors, specifying additional high temperature tests in clamp slip tests.
c) Simplify the procedure of the damper effectiveness evaluation.
d) Introduce test at low temperature on fastener components such as break away bolts and conical spring washers.
e) Include figures showing the test arrangements for the main mechanical tests.
Key words: Overhead Lines, Aeolian Vibration Dampers

IEC 62574:2020 is available as IEC 62574:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 62574:2020 specifies the general channel assignment and the metadata for multichannel audio format. This document, with its channel mapping and labelling content, provides the unified usage of channel assignments for source devices, digital audio interfaces and sink devices. The general channel assignment excludes the specification of the exact position of each loudspeaker. The metadata has the exact position of each loudspeaker; however, since the position of the loudspeaker is different in various surround sound formats, the position information of the metadata is not standardized. It is aimed at consumer applications; it is not targeted at theatrical environments. Up to 65 labels for loudspeaker positions and 15 labels for loudspeakers on the display are specified, which can be used for all current multichannel audio formats. The channel assignment concept is room centric and listener centric. This general channel assignment specifies the position of the loudspeaker as seen from the listener.
IEC 62574:2020 cancels and replaces the first edition published in 2011. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) model of channel assignment spaces is changed;
b) definition of channel maps and labels is changed;
c) metadata is newly specified;
d) channel maps and labels from the first edition are included in Annex A.
