Cleanrooms and associated controlled environments — Part 21: Airborne particle sampling techniques
This document discusses the physical limitations of probe and particle counter placement, and any tubing that connects the two, particularly in providing representative samples where particles 5 micrometres and greater are of interest. The document further identifies the key factors of sampling performance when classifying and monitoring, and good practice to determine and maintain an acceptable…

Microgrids - Part 3-3: Technical requirements - Self-regulation of dispatchable loads
IEC TS 62898-3-3:2023 deals with frequency and voltage stabilization of AC microgrids by dispatchable loads, which react autonomously on variations of frequency and voltage with a change in active power consumption. Both 50 Hz and 60 Hz electric power systems are covered. This document gives requirements to emulate the self-regulation effect of loads including synthetic inertia. The loads…
