Fine bubble technology — Evaluation method for determining gas content in fine bubble dispersions in...
This document specifies evaluation methods for the oxygen content in fine bubble dispersion in water.
Three test methods which are adopted include the optical sensor, the electrochemical probe and the iodometric method. The first two methods have an advantage in availability of in situ and real-time measurement, and high accessibility to commercially available instruments. The last one, composed…

Measuring autofocus repeatability of sharpness and latency
This document is focused on measuring the autofocus (AF) repeatability of sharpness and latency, meaning camera system’s capability to produce sharp images within certain time frame. The scope of document is limited to testing autofocus sharpness and latency repeatability with stationary charts only as testing with moving charts is not covered.

Iron ores for blast furnace feedstocks — Determination of the decrepitation index
This document specifies a method to provide a relative measure for evaluating the degree of size degradation caused by rapid heating of iron ores. It specifies the determination of the decrepitation index.
This document is applicable to lump ores for blast furnace feedstocks.
Rotating electrical machines - Part 2-3: Specific test methods for determining losses and efficiency...
IEC 60034-2-3:2024 specifies test methods and an interpolation procedure for determining losses and efficiencies of converter-fed motors. The motor is then part of a variable frequency power drive system (PDS) as defined in IEC 61800‑9‑2. This document also specifies procedures to determine motor losses at any load point (torque, speed) within the constant flux range (constant torque range, base…
Machines électriques tournantes - Partie 2-3: Méthodes d'essai spécifiques pour la déterminatio...
L'IEC 60034-2-3:2024 spécifie les méthodes d'essai et la procédure d'interpolation relatives à la détermination des pertes et des rendements des moteurs alimentés par convertisseur. Le moteur est alors considéré comme faisant partie intégrante d'un système d'entraînement électrique de puissance (PDS) à fréquence variable, comme cela est défini dans l'IEC 61800‑9‑2.…
