Wind energy generation systems - Part 24: Lightning protection
IEC 61400-24:2019 applies to lightning protection of wind turbine generators and wind power systems. Refer to guidelines for small wind turbines in annex.<br />
This document defines the lightning environment for wind turbines and risk assessment for wind turbines in that environment. It defines requirements for protection of blades, other structural components and electrical and control…
Space systems — Disposal of satellites operating at geosynchronous altitude
This document specifies requirements for the following:
— planning for disposal of a spacecraft operating at geosynchronous altitude to ensure that final disposal is sufficiently characterized and that adequate propellant will be reserved for the manoeuvre;
— selecting final disposal orbits where the spacecraft will not re-enter the operational region within the next 100 years…

Footwear sizing — Mondopoint system of sizing and marking
This document specifies a method of designation and marking of footwear size called Mondopoint, based on defined measurements of the foot that the footwear is intended to fit.
This document is applicable to all types of footwear.
Rubber, vulcanized or thermoplastic — Determination of volume and/or surface resistivity
This document specifies a method for the determination of the volume and the surface resistivity of vulcanized or thermoplastic rubbers. The method can be applied to materials with a resistivity from 101 Ω⋅m to 1017 Ω⋅m.
Determination of particle density by sedimentation methods — Part 2: Multi-velocity approach
This document specifies an in situ method for the determination of the density of solid particles or liquid droplets (herein referred to as "particle") dispersed in liquid continuous phase. The method is based on direct experimental determination of particle velocity in these liquids or media in gravitational or centrifugal fields based on Stokes law. The particle density is calculated…
