This document specifies: — the physical and chemical tests on raw rubbers; — the standard materials, standard test formulations, equipment, and processing methods for evaluating the vulcanization characteristics of ethylene-propylene-diene rubbers (EPDM), including oil-extended types.

IEC 62149-5:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62149-5:2020 specifies performance on the transceiver modules for asynchronous-transfer-mode passive optical…

IEC 62828-5:2020 establishes specific procedures for testing flow transmitters used in measuring and control systems for industrial process and for machinery control systems. For general test procedures, reference is to be made to IEC 62828-1:2017, applicable to all types of industrial and process measurement transmitters. This document – together with IEC 62828-1:2017 – is the reference…

IEC 62149-5:2020 specifies performance on the transceiver modules for asynchronous-transfer-mode passive optical network (ATM-PON) systems recommended by the International Telecommunication Union (ITU) in ITU-T Recommendation G.983.1. This third edition cancels and replaces the second edition published in 2009 and constitutes a technical revision. This edition includes the following significant…

This document specifies the geometry and method of use (installation and operating conditions) of nozzles and Venturi nozzles when they are inserted in a conduit running full to determine the flowrate of the fluid flowing in the conduit. This document also provides background information for calculating the flowrate and is applicable in conjunction with the requirements given in ISO 5167‑1. This…

This document specifies methods of determining the stage?discharge relationship for gauging stations. It specifies an accuracy for defining the stage?discharge relationship based on a sufficient number of discharge measurements, complete with corresponding stage measurements. This document considers stable and unstable channels and includes brief descriptions of the effects on the stage?discharge…

1 Scope and object This clause of Part 1 is applicable except as follows: 1.1.1 Equipment included in scope Replace the existing text with the following: This part of IEC 61010 specifies safety requirements for HAND-HELD and hand-manipulated current sensors described below. These current sensors are for measuring, detecting or injecting current, or indicating current waveforms on circuits…
