IEC 61557-2:2019 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 61557-2:2019 specifies the requirements applicable to equipment for measuring the insulation resistance of…

IEC 61557-6:2019 specifies the requirements applicable to measuring equipment for testing the effectiveness of protective measures of residual current devices (RCD) installed in TT, TN and IT systems. It is not the purpose of this document to verify the RCD according to their product standards. IEC 61557-6:2019 cancels and replaces the second edition published in 2007. This edition constitutes a…

IEC 61557-3:2019 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 61557-3:2019 specifies the requirements applicable to equipment for measuring the loop impedance between a line…

This document describes methods for measuring the thickness of coatings applied to a substrate. Methods for determining wet-film thickness, dry-film thickness and the film thickness of uncured powder layers are described. For each method described, this document provides an overview of the field of application, existing standards and the precision. Information on measuring film thickness on rough…

This document specifies an order for listing elements within the chemical composition of steels and most other iron-based alloys, excluding foundry irons. NOTE This document has been developed and is used by ISO/TC 17/SC 4, but can also be used by other ISO/TC 17 subcommittees.

This document specifies test specimens and procedures for performing constant load amplitude fatigue tests on multi-spot-welded and multi-axial specimens in the thickness range from 0,5 mm to 5 mm at room temperature and a relative humidity of maximum 80 %. The applicability of this document to larger thicknesses can be limited by mechanical properties such as yield strength and formability of…

This document specifies a method for the determination of creep in vulcanized rubber continuously subjected to compressive or to shear forces. The standard cannot be used for intermittent deformation of rubber.

IEC Guide 104:2019(E) is mandatory and defines procedures for the preparation of safety publications in addition to ISO/IEC Guide 51, including the preparation and use of basic safety publications and group safety publications. Also describes the relationship between TCs with horizontal safety functions or group safety functions and product TCs. In the context of this guide, "safety"…

This document specifies a number of methods of determining the dimensional changes in test pieces of vulcanized or thermoplastic rubber during and after tensile loading for relatively short periods under constant elongation or constant loading. The constant-elongation test is intended to measure the ability of rubbers to retain their elastic properties after extension, at a standard laboratory…

This document specifies rules for the creation and extending of TPEG application UML models. The rules are intended to ensure that TPEG application UML models can be interpreted unambiguously for conversion to physical format representations. TPEG application UML models that are defined according to these rules can be used for automatic generation of TPEG standards and for automatic generation of…
