Electromagnetic compatibility (EMC) - Part 2-9: Environment - Description of HEMP environment - Radi...
IEC 61000-2-9: 2025 defines the high-altitude electromagnetic pulse (HEMP) environment that is one of the consequences of a high-altitude nuclear explosion. There are two cases of nuclear detonations:
- high-altitude nuclear explosions;
- low-altitude nuclear explosions.
For civil systems, the most important case is the high-altitude nuclear explosion. In this case, the other effects of the…
Gas analysis — Conversion of gas mixture composition data
This document defines the following quantities commonly used to express the composition of gas mixtures:
— amount fraction and concentration;
— mass fraction and concentration;
— volume fraction and concentration.
For these quantities of composition, this document specifies methods for:
— conversion between different quantities;
— conversion between different state conditions…
Acoustics — Measurement of sound absorption properties of road surfaces in situ — Part 2: Spot metho...
This document specifies a test method for measuring in situ the sound absorption coefficient of road surfaces for the one-third octave band frequencies ranging from 250 Hz to 1 600 Hz under normal incidence conditions. If necessary for practical applications the diameter of the tube can be reduced to 80 mm. This will increase the upper boundary of the frequency range to 2 000 Hz one-third octave…
