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…

IEC 60400:2017+A1:2020 states the technical and dimensional requirements for lampholders for tubular fluorescent lamps and for starterholders, and the methods of test to be used in determining the safety and the fit of the lamps in the lampholders and the starters in the starterholders. This eighth edition cancels and replaces the seventh edition published in 2008, Amendment 1:2011 and Amendment…

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…

This document specifies the engineering 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,…

IEC 60079-6:2015+A1:2020 specifies the requirements for the design, construction, testing and marking of Ex Equipment and Ex Components with type of protection liquid immersion "o" intended for use in explosive gas atmospheres. Ex Equipment and Ex Components of type of protection liquid immersion "o" are either: - Level of Protection "ob" (EPL "Mb" or…

IEC 61850-8-1:2011+A1:2020 specifies a method of exchanging time-critical and non-time-critical data through local-area networks by mapping ACSI to MMS and ISO/IEC 8802-3 frames. Defines a standardized method of using the ISO 9506 services to implement the exchange of data. For those ACSI services defined in IEC 61850-7-2 that are not mapped to MMS, this part defines additional protocols. It…

ISO/IEC TR 11801-9906:2020(E) covers channel specifications, for channels constructed from balanced 1 pair cabling components, primarily intended for use in industrial automation and process control applications. The channel specifications are consistent with corresponding IEEE 802.3 single-pair Ethernet (SPE) applications and are referenced from link segment specifications in the following IEEE…

This document specifies the reference test methods for determining the physical optical properties of personal eye and face protectors. This document does not apply to any eye and face protection products for which the requirements standard(s) specifies other test methods. Other test methods can be used provided they have been shown to be equivalent and include uncertainties of measurement no…

IEC 60335-2-107:2017+A1:2020 specifies safety requirements and their verification for the design and construction of robotic battery powered electrical rotary lawnmowers and their peripherals with the rated voltage of the battery being not more than 75 V d.c. EMC and environmental aspects, except noise, have not been considered in this standard. This document does not apply to the additional…
