This document applies to an MFC with declared maximum inlet pressures up to and including 50 kPa (500 mbar) of nominal connection sizes up to and including DN 150 for use on burners or in appliances…

IEC 63267-1: 2023 covers enhanced macrobend loss 50 µm core diameter multimode fibre optic connection interfaces. It includes references, document structure details, definitions, and standardised optical connection grades. The grades are based on random mated connections between two optical connector populations according to prescribed characteristics including the core diameter and numerical…

This document defines the requirements for the external test equipment as: —    a means of establishing communications between a WWH-OBD-equipped vehicle and external test equipment; —    a set of diagnostic services, including addressing methods, to be provided by the external test equipment in order to exercise the services defined in ISO 27145‑3. This document describes the minimum…

IEC PAS 63472:2023 describes dimensional options for CONFIGURATION FF AC/DC contact-tube vehicle couplers as defined in IEC 62196-3. These possibilities serve to improve the reliability of a mated connection when the charging cable is not axially constrained. The options can be implemented optionally and maintain mating compatibility with CONFIGURATION FF according to IEC 62196-3.

IEC 63027:2023 applies to equipment used for the detection and optionally the interruption of electric DC arcs in photovoltaic (PV) system circuits. The document covers test procedures for the detection of series arcs within PV circuits, and the response times of equipment employed to interrupt the arcs. The document defines reference scenarios according to which the testing is conducted. This…

1 Scope 1.1 Inclusions This Standard sets forth a set of minimum performance requirements for portable engine fuelling systems (PEFS) with a rated capacity of not more than 32 L (8.45 US gal), designed to be connected to gasoline-fueled engines aboard boats by flexible fuel lines that can be disconnected for refilling and portability. It applies to PEFS intended to be used with gasoline…
