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…

Measurement of radioactivity in the environment — Guidelines for effective dose assessment using env...
These international guidelines are based on the assumption that monitoring of environmental components (atmosphere, water, soil and biota) as well as food quality ensure the protection of human health[2][4][5][6][7][8]. The guidelines constitute a basis for the setting of national regulations and standards, inter alia, for monitoring air, water and food in support of public health, specifically…
