This document specifies the principles and procedures for estimating the thermal endurance of rubbers from the results of exposure to elevated temperatures for long periods. Two approaches are specified (see Introduction): —    one using the Arrhenius equation; —    the other using the WLF equation. In this document, the estimation of thermal endurance is based solely on the change in selected…

This document specifies the measurement and acceptance criteria and the test report of hydraulic performance tests for waterjet propulsion system of Class A and Class B. The test methods for the waterjet propulsion pump with and without the inlet duct are both specified. This document is applicable to the hydraulic performance test of water jet propulsion under the specified test conditions.…

Le présent document spécifie les principes et les méthodes pour l'estimation de l'endurance thermique des caoutchoucs d'après les résultats d'une exposition à des températures élevées pendant de longues périodes. Deux méthodes sont spécifiées (voir l'introduction): —    l'une utilisant l'équation d'Arrhenius; —    l'autre utilisant l'équation de…

IEC 60904-2:2023 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 60904-2:2023 edition 4.0 and the previous IEC 60904-2:2015 edition 3.0. Furthermore, comments from IEC TC 82 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the…

IEC 60904-2:2023 gives requirements for the classification, selection, packaging, marking, calibration and care of photovoltaic reference devices. This document applies to photovoltaic (PV) reference devices that are used to measure the irradiance of natural or simulated sunlight for the purpose of quantifying the electrical performance of photovoltaic devices (cells, modules and arrays). It does…
