Fire performance of communication cables installed in buildings
IEC TR 62222:2021 describes the test methods for various parameters relating to the reaction to fire properties of metallic and optical fibre communications cables. The parameters have particular importance for cables intended to be installed within buildings and other structures. This document also maps the test methods and associated limits applied to the fire hazards created by particular…
Power transformers - Part 22-5: Power transformer and reactor fittings - Electric pumps for transfor...
IEC 60076-22-5:2021 covers electric pumps used in the cooling circuits of power transformers and reactors. It applies to electric pumps mounted on liquid immersed power transformers according to IEC 60076-1 and reactors according to IEC 60076-6 with and without conservator for indoor or outdoor installation.
It outlines the operation requirements for the electrical and hydraulic performance,…
Monitoring radioactive gases in effluents from facilities producing positron emitting radionuclides ...
This document focuses on monitoring the activity concentrations of radioactive gases. They allow the calculation of the activity releases, in the gaseous effluent discharge from facilities producing positron emitting radionuclides and radiopharmaceuticals. Such facilities produce short-lived radionuclides used for medical purposes or research and can release gases typically including, but not…
Public transport — Interoperable fare management system — Part 1: Architecture
This document gives guidelines for the development of multi-operator/multi-service interoperable public surface (including subways) transport fare management systems (IFMSs) on a national and international level.
This document is applicable to bodies in public transport and related services which agree that their systems need to interoperate.
This document defines a conceptual framework which is…
