This document reviews the structural changes that have been precipitated by the COVID-19 pandemic in Remote Connected Care and Mobile Health (RCC-MH). The impact of the COVID-19 pandemic on care settings such as home and community care, acute care and outpatient care are reviewed discussing how well these healthcare environments were prepared to address the encountered connectivity challenges from a standards point of view. The current standards landscape is reviewed and gaps are identified leading to recommendations for future standards work.

This document specifies measurement methods and conditions to obtain reproducible and comparable exterior noise emission levels and spectra for all kinds of vehicles operating on rails or other types of fixed track, hereinafter conventionally called “unit”. This document is applicable to type testing of units. It provides measurement procedures for vehicle exterior noise (in general, a vehicle type test is carried out using only a selected subset of these tests): — when the vehicle is moving at constant speed; — when the vehicle is accelerating or decelerating; — when the vehicle is stationary in different operating conditions. It does not include all the instructions to characterize the noise emission of the infrastructure related sources (bridges, crossings, switching, impact noise, curving noise, etc.). This document does not apply to — the noise emission of track maintenance units while working, — environmental impact assessment (collection of data to be used in a prediction method for environmental assessment), — noise immission assessment, — guided buses, and — warning signal noise. The results can be used, for example — to characterize the exterior noise emitted by units, — to compare the noise emission of various units on a particular track section, and — to collect basic source data for units. NOTE Additional guidance is provided in Annex E for measurements in the specific case of urban rail vehicles.

IEC 60122-2:2025 has been compiled in response to a generally expressed desire on the part of both users and manufacturers for guidelines to the use of quartz crystal units for filters and oscillators so that the crystal units may be used to their best advantage.
It draws attention to some of the more fundamental questions which will be considered by the user before it places its order for a unit for a new application, and in so doing will, it is hoped, help ensure against unsatisfactory performance, unfavourable cost and non-availability. It is not the function of this document to explain theory, nor to attempt to cover all the eventualities that can arise in practical circumstances. Lastly, it it is not considered as a substitute for close liaison between manufacturer and user.
Standard specifications, such as those of the IEC of which these guidelines form a part, and national specifications or detail specifications issued by manufacturers, will define the available combinations of the resonant characteristics and the temperature characteristic. These specifications are compiled to include a wide range of quartz crystal units with standardized performances. It cannot be over-emphasized that it is the responsibility of the user , wherever possible, to select the quartz crystal units from these specifications, when available, even if it can lead to making small modifications to the circuit to enable the use of standard resonators. This applies particularly to the selection of the nominal frequency.
