This part of IEC 62977 specifies the standard evaluation methods for determining the optical characteristics of HDR electronic display modules and systems. These methods apply to emissive and transmissive direct-view displays that render real 2D images on a flat panel or on a curved panel with a local radius of curvature larger than 1500 mm. This document evaluates the optical characteristics of these displays under darkroom conditions. This document applies to the testing of display performance in response to HDR digital input signals that are absolute luminance encoded such as the HDR signal comprising RGB component values of ITU-R BT.2020 colorimetry with SMPTE ST 2084 PQ luminance encoding and SMPTE ST 2086 metadata.

NOTE 1 A flat panel or flat panel display is a display with a planar surface that emits light from the surface. The display can consist of light valves modulating a backlight or be self-luminous. Emissive/transmissive/reflective hybrid displays can be non-planar panel or non-planar panel displays.

NOTE 2 In this document, “high dynamic range” is abbreviated as “HDR”, for example, “An HDR display is capable of rendering the content.”

This part of IEC 61280-4 describes the measurement of attenuation, optical return loss and optical power in installed passive optical networks (PON) using single-mode fibre.

This document specifies two methods for measuring the attenuation before activation of the PON:

Method A: One-cord method using a light source and a power meter (LSPM);

Method B: Optical time-domain reflectometer (OTDR) method in upstream direction only, with reduction of uncertainties due to the variation of backscatter coefficient.

In addition, method C, which is described in informative Annex C, provides an estimate of the attenuation after partial activation of the PON by using a U band filtered optical time-domain reflectometer (FOTDR) in an upstream direction.

This part of IEC 62056 specifies the overall structure of the OBject Identification System (OBIS) and the mapping of all commonly used data items in metering equipment to their identification codes.

OBIS provides a unique identifier for all data within the metering equipment, including not only measurement values, but also abstract values used for configuration or obtaining information about the behaviour of the metering equipment. The ID codes defined in this document are used for the identification of:

logical names of the various instances of the ICs, or objects, as defined in IEC 62056-6-2:2021;

data transmitted through communication lines;

data displayed on the metering equipment, see Clause A.2.

This document applies to all types of metering equipment, such as fully integrated meters, modular meters, tariff attachments, data concentrators, etc.

To cover metering equipment measuring energy types other than electricity, combined metering equipment measuring more than one type of energy or metering equipment with several physical measurement channels, the concepts of medium and channels are introduced. This allows meter data originating from different sources to be identified. While this document fully defines the structure of the identification system for other media, the mapping of non-electrical energy related data items to ID codes is completed separately.

NOTE EN 13757-1:2014 defines identifiers for metering equipment other than electricity: heat cost allocators, thermal energy, gas, cold water and hot water.

This part of IEC 61340 provides test methods for measuring the electrical resistance of garments used for static control applications. These test methods can be used for evaluating outer garments that are homogenously conductive or homogeneously dissipative, or that utilize surface conductive or surface dissipative components or elements.

NOTE The test methods defined in this standard might not be able to measure materials with buried conductive layers.

The resistance point-to-point test method tests the electrical resistance between the two sleeves, any two panels or any two or more electrically interconnected components of the static control garment, including the electrical resistance across the seams and cuffs of the garment as applicable.

An alternate sleeve-to-sleeve test method is allowed, using clamps to hang a garment.

Static control garments that electrically bond to the wearer and provide a path to ground from the wearer are evaluated using the resistance point-to-point test method, the resistance point to groundable point test method, as well as a system test to determine the resistance from the person through the garment to the groundable point of the garment system.

A band resistance measurement test is provided in IEC 61340-4-6 which can be used for garments so equipped with cuffs that are intended to perform the same function as a wrist strap band.

The system test with a person wearing a groundable static control garment system includes the ground cord that connects to the groundable point of the garment.

This standard describes the measurement of screening attenuation by the reverberation chamber measurement method, also called mode stirred chamber method.

This standard is applicable to screening attenuation measurements of cable assemblies, cables, connectors, and passive microwave components, such as waveguides, phase shifters, diplexers/multiplexers, power dividers/combiners and etc.

Modern electronic equipments have shown a demand for methods for testing screening attenuation performance of microwave components over their whole frequency range. Convenient measurement methods have existed for lower frequencies and components of regular shape. These measurement methods are described in IEC 62153 series standards. For much higher frequencies and for components of irregular shape, the reverberation chamber method should be used. Theoretically, the reverberation chamber method has no upper limit of the measurement frequency, but it is limited by the quality and sensitivity of the measurement system, and the lower limit of the measurement frequency is restricted by the size of the reverberation chamber.

This International Standard applies to personal dosemeters with the following characteristics:

a)  They are worn on the trunk, close to the eye, or on the extremities.

b)  They measure the personal dose equivalents Hp(10), Hp(3), and Hp(0,07), from external X and gamma, neutron (not for Hp(3)), and beta radiations, and may measure the respective personal dose equivalent rates for the same radiations (for alarming purposes).

c)  They have a digital indication. This indication may or may not be attached.

d)  They shall have alarm functions for the personal dose equivalents or personal dose equivalent rates except for hybrid dosemeters

NOTE 1 When reference is made in this standard to ”dose”, this is meant to indicate personal dose equivalent, unless otherwise stated.

NOTE 2 When reference is made in this standard to ”dosemeter”, this is meant to include all personal dosemeters, unless otherwise stated.

NOTE 3  This standard does not cover neutron doesemeters for the Hp(3) measurements up to now.

This standard specifies requirements for the dosemeter and, if supplied, for its associated readout system.

Usually, a dosemeter is not able to measure all quantities given above. Thus, the dosemeter is only tested with regard to those quantities and types of radiation it is intended to be used for. Other types of radiation are considered as influence quantities which also may have requirements.

This standard specifies, for the dosemeters described above, general characteristics, general test procedures, radiation characteristics as well as electrical, mechanical, safety and envi­ronmental characteristics. The only requirements specified for associated readout systems are those which affect its accuracy of readout of the personal dose equivalent and alarm settings, and those which concern the influence of the reader on the dosemeter.

This standard does not cover special requirements for accident or emergency dosimetry although the dosemeters may be used for this purpose.

The standard does not apply to dosemeters used for measurement of pulsed radiation, such as radiation emanating from many medical diagnostic X-ray facilities, linear accelerators or similar equipment.

NOTE Requirements and testing procedure for dosemeters to be used in pulsed field of ionizing radiation can be found in IEC TS 63050 or IEC TS 62743.

The standard does not apply for dosemeters to measure ambient or directional dose equivalent.

NOTE Requirements for ambient or directions dose equivalent meters can be found e.g. in: IEC 60846-1; IEC 62387, IEC 61017 or IEC 60532.
