Power quality management - Part 3: User characteristics modelling
IEC TS 63222-3:2024 is intended to provide provisions regarding recognized engineering practices applicable to assess the user’s characteristics in power quality predicted assessment. It summarizes the best practice in non-linear, unbalanced, impact and fluctuating loads or generations modelling for power quality disturbance anticipation in public power systems at the planning stage.

Solid biofuels — Determination of particle size distribution for uncompressed fuels — Part 2: Vibrat...
This document specifies a method for the determination of the size distribution of particulate biofuels by the vibrating screen method. The method described is meant for particulate biofuels only, namely, materials that either have been reduced in size, such as most wood fuels, or are physically in a particulate form. This document applies to particulate uncompressed fuels with a nominal top size…
Solid biofuels — Determination of particle size distribution for uncompressed fuels — Part 1: Oscill...
This document specifies a method for the determination of the size distribution of particulate biofuels by the horizontally oscillating screen method. It applies to particulate uncompressed fuels with a nominal top size of 3,15 mm and above, e.g. wood chips, hog fuel, olive stones.
The method is intended to characterize material up to a particle size class (P) of P63. For larger P-classes and PL-…
