1 Scope 1.1 This Standard applies to locking-type, pin and sleeve type plugs, receptacles, power inlets, connectors, junction boxes, and live-end covers rated up to 1200 A (for single- and multi-pole) and above 750 V to 35 kV ac, 50/60 Hz or up to 1500 V dc and which shall have one or more pilot contacts for multi-pole configuration and above 750 V to 1000 V ac or dc for single pole…

1 Scope 1.1 This Standard applies to open-type (fused and solid-blade) cutouts with a polymeric insulator structure component. These cutouts are intended for operation on alternating current distribution systems. 1.2 In some cases, specific types of construction are envisaged. This does not preclude the use of other types of construction, provided that the engineering representatives involved…

This document specifies the method for rotating bar bending fatigue testing of metallic materials. The tests are conducted at room temperature or elevated temperature in air, the specimen being rotated. Fatigue tests on notched specimens are not covered by this document, since the shape and size of notched specimens have not been standardized. However, fatigue test procedures described in this…

IEC 60652:2021 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 60652:2021 specifies the methods and procedures of testing supports for overhead lines. It applies to the testing…

This document specifies a method for the determination of the green strength of raw rubber or unvulcanized rubber compounds using a tensile stress-strain test, the test pieces being prepared following standard test conditions or cut from calendered sheets.

IEC 62841-3-12:2017+A1:2021 applies to transportable threading machines. The rated voltage is not more than 250 V for single-phase a.c. or d.c. tools, and 480 V for three-phase a.c. tools. The rated input is not more than 3 700 W. The limits for the applicability of this standard for battery tools are given in Annex K. This standard deals with the hazards presented by tools which are encountered…

IEC TR 62908-1-3:2021, which is a technical report, provides general information on pen touch technology with the aim toward standardization. This document includes an overview of the pen touch technology, critical performance characteristics, issues of characteristics measurements, and other information. The purpose of this documents is to provide an overview of the different products available…

IEC 60255-187-1:2021 specifies the minimum requirements for functional and performance evaluation of (longitudinal) differential protection designed for the detection of faults in ac motors, generators and transformers. This document also defines how to document and publish performance test results. This document defines the influencing factors that affect the accuracy under steady state…

This document specifies a general protocol for the observation of the meiofaunal community in the deep seabed. The standardized method can be used in any phase [baseline data acquisition, monitoring during and after mining (testing)] accompanying resource development, making it easier to compare data beyond differences in workers and waters. This document is intended for marine environment impact…

This document specifies a bioassay for the determination of the presence of unknown toxic contaminants in test seawater (see Figure A.1). It is based on the inhibition of photosynthetic activity of the marine cyanobacterium Cyanobium sp. (NIES-981) by such toxic contaminants. The inhibition is determined based on delayed fluorescence (DF) intensity. The method is rapid and requires less…
