IEC 61557-13:2023 defines special performance requirements for hand-held and hand manipulated current clamps and sensors for measurement of leakage currents in electrical distribution systems up to 1 000 V AC and 1 500 V DC taking into account the influence of high external low-frequency magnetic fields and other influencing quantities. See Annex A for examples of measurement applications. This…

IEC 62788-2-1:2023 specifies the safety requirements for flexible polymeric front- and backsheet constructions, which are intended for use as relied-upon insulation in photovoltaic (PV) modules. The specifications in this document define the specific requirements of polymeric front- or backsheet constructions on the component level and cover mechanical, electrical, visual and thermal…

This document defines visual aspects for the identification and assessment of product characteristics for friction materials in terms of quality and for commercial and technical agreements. The sequence of the product characteristics represents no order of priority. Inspection is carried out in unused, “as supplied” condition. In some characteristic features, there are differences between brake…

IEC 62271-202:2022 specifies the service conditions, rated characteristics, general structural requirements and test methods of enclosed high-voltage prefabricated substations. These prefabricated substations are cable-connected to AC high-voltage networks with an operating voltage up to and including 52 kV and power frequencies up to and including 60 Hz. They can be manually operated from inside…

2 SCOPE This standard applies to any products containing a claimed recycled plastic content of at least 5%, which is either credited according to the Chain of Custody (CoC) mass balance model or actual physical recycled content. This standard is not intended to determine the mechanical, physical and chemical qualities and properties of a product, nor the adequacy of the product’s constraint…

This document defines an integrated XML implementation of ISO 19115-1 and ISO 19115-2 by defining the following artefacts: —     a set of XML schema required to validate metadata instance documents conforming to conceptual model elements defined in ISO 19115-1 and ISO 19115-2; and —     a set of ISO/IEC 19757-3 (Schematron) rules that implement validation constraints in the ISO 19115-1 and ISO…

IEC TR 61850-90-7:2023 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 TR 61850-90-7:2023, which is a Technical Report, describes functions for power converter-based distributed…

IEC TR 61850-90-7:2023, which is a Technical Report, describes functions for power converter-based distributed energy resources (DER) systems, focused on DC-to-AC and AC-to-AC conversions and including photovoltaic systems (PV), battery storage systems, electric vehicle (EV) charging systems, and any other DER systems with a controllable power converter. The functions defined in this document…

This document defines terms for brakes and braking in rolling stock.
