1 Scope Replacement: This International Standard deals with all aspects of safety such as electrical, thermal and mechanical. This part 2-13 of IEC 61558 applies to stationary or portable, single-phase or polyphase, aircooled (natural or forced), independent or associated auto-transformers, having a rated supply voltage not exceeding 1 000 V a.c., a rated frequency not exceeding 500 Hz…

1 Scope Replacement: This part of IEC 61558 deals with the safety of isolating transformers for general applications and power supply units incorporating isolating transformers for general applications. Transformers incorporating electronic circuits are also covered by this standard. NOTE 1 Safety includes electrical, thermal and mechanical aspects. Unless otherwise specified, from here…

1 Domaine d’application 1.1 Ces exigences s’appliquent aux systèmes de stockage de l’énergie (ESS) destinés à recevoir de l’énergie et à l’emmagasiner sous une forme qui peut approvisionner en énergie électrique, selon la nécessité, des charges ou le système d’alimentation électrique (EPS) local/d’un secteur. La présente norme traite des modes de stockage de l’énergie suivants :…

This document specifies the survey method, which is the measurement method of the sound power level for reciprocating internal combustion engines. This document applies to all reciprocating internal combustion engines falling within the field of application of ISO 3046‑1 and other internal combustion engines where no suitable International Standard exists. NOTE In this document, reciprocating…

IEC 62148-6:2020 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 62148-6:2020 covers the physical interface specification of optical transceivers for asynchronous transfer mode-…

IEC 62148-6:2020 covers the physical interface specification of optical transceivers for asynchronous transfer mode-passive optical network (ATM-PON) systems recommended by the International Telecommunication Union (ITU) as ITU Recommendation G.983.1. This second edition cancels and replaces the first edition published in 2003, and constitutes a technical revision. This edition includes the…

This practice covers the preparation and use of semiadiabatic calorimetric dosimetry systems for measurement of absorbed dose and for calibration of routine dosimetry systems when irradiated with electrons for radiation processing applications. The calorimeters are either transported by a conveyor past a scanned electron beam or are stationary in a broadened beam. This document is one of a set of…
