IEC TR 62559-1:2019, which is a Technical Report, is the basis for a common use case repository, used to gather use cases within IEC on a common collaborative platform. The repository is used to organize and harmonize use cases in order to provide broadly accepted generic use cases as basis for the further standardization work. This document gives an overview about the individual parts of the…

This document provides product specifications for tactile walking surface indicators (TWSIs) and recommendations for their installation in order to assist in the safe and independent mobility of blind or vision-impaired persons. This document specifies two types of TWSIs: attention patterns and guiding patterns. Both types can be used indoors and outdoors throughout the built environment where…

IEC 60122-4:2019 is applicable to crystal units with thermistors mainly used in the field of mobile communication that requires high frequency stability such as local reference signal generator for the mobile phone base station or GPS. This document provides users with technical guidelines of crystal units with thermistors as well as basic knowledge of common crystal units with thermistors

This document specifies the characteristics and production methods of X and gamma reference radiation for calibrating protection-level dosemeters and doserate meters with respect to the phantom related operational quantities of the International Commission on Radiation Units and Measurements (ICRU)[5]. The lowest air kerma rate for which this standard is applicable is 1 µGy h?1. Below this air…

This document specifies the procedures for the dosimetry of X and gamma reference radiation for the calibration of radiation protection instruments over the energy range from approximately 8 keV to 1,3 MeV and from 4 MeV to 9 MeV and for air kerma rates above 1 µGy/h. The considered measuring quantities are the air kerma free-in-air, Ka, and the phantom related operational quantities of the…

IEC 60674-3-2:2019 gives the requirements for balanced biaxially oriented polyethylene terephthalate (PET) films used for electrical insulation. Safety warning: It is the responsibility of the user of the methods contained or referred to in this document to ensure that they are used in a safe manner. Keywords: plastic films for electrical purposes, balanced biaxially oriented polyethylene…

This document specifies requirements for single-use sharps containers intended to hold potentially hazardous sharps medical waste with or without sharps protection features, e.g. scalpel blades, trocars, hypodermic needles and syringes. It is applicable to single-use sharps containers that are supplied complete by the manufacturer and to those that are supplied as components intended to be…

This document specifies the omnidirectional media format for coding, storage, delivery, and rendering of omnidirectional media, including video, images, audio, and timed text. In an OMAF player the user's viewing perspective is from the centre of the sphere looking outward towards the inside surface of the sphere. NOTE 1 In this document, only 3 degrees of freedom (3DOF) is supported. In…
