Domaine d’application 1.1 Ces exigences s’appliquent aux systèmes de luminaires dont l’alimentation électrique provient de modules photovoltaïques. Les systèmes comprennent un module photovoltaïque (PV), des batteries de stockage, un ou plusieurs luminaires colocalisés et des commandes pour gérer le flux d’énergie entre ces sous-ensembles. Ces systèmes sont destinés à être installés…

This document provides guidance on the staged implementation of Electric, Connected and Autonomous Vehicle (eCAV) passenger and delivery services, with a special focus on on-demand responsive passenger services with shared vehicles. This document aims to accelerate innovation and deliver smart transportation by eCAV, in and between cities. Note 1 to entry:       This document does not designate…

This document specifies requirements, test methods and performance criteria for line-type smoke detectors for use in fire detection systems installed in buildings. The detectors consist of at least a transmitter and a receiver and can include reflector(s) for the detection of smoke by the attenuation and/or changes in attenuation of an optical beam. This document is not applicable to: —    line-…

This document specifies dimensions for metric ports for use with the adjustable and non-adjustable stud ends as described in ISO 6149‑2 and ISO 6149‑3. Ports in accordance with this document can be used at working pressures up to 63 MPa (630 bar[1]) for non-adjustable stud ends and 40 MPa (400 bar) for adjustable stud ends. The permissible working pressure depends upon port size, materials,…

This document specifies the requirements and recommendations for the design, setting depth and installation of conductors for the offshore petroleum and natural gas industries. This document specifically addresses: —    design of the conductor, i.e. determination of the diameter, wall thickness, and steel grade; —    determination of the setting depth for three installation methods, namely,…

1 Scope 1.1 Applicable equipment This Standard applies to newly produced outdoor cooking gas appliances (see Clause 3) constructed entirely of new, unused parts and materials. Outdoor cooking gas appliances submitted for examination under this Standard are classified as portable, stationary, or built-in. 1.2 Applicable equipment for recreational vehicle This Standard applies to outdoor…

This document specifies a method for the determination of fuel consumption and resulting CO2 emissions to enable fleet managers to reduce fuel costs and greenhouse gas (GHG) emissions in a sustainable manner. The fuel consumption determination is achieved by extracting trip data and speed profiles from the global navigation satellite system (GNSS) receiver of a nomadic device (ND), by sending it…

This document specifies the following, in order to determine the corrosiveness of gases and gas mixtures so that a suitable outlet connection can be assigned to each of them: —    for pure gases and some liquids, a complete list indicating their corrosiveness; —    for gas mixtures, a calculation method, in the absence of experimental data, relating to the corrosiveness of each of their…

IEC 62271-203:2022 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 62271-203:2022 edition 3.0 and the previous IEC 62271-203:2011 edition 2.0. Furthermore, comments from IEC SC 17C experts are provided to explain the reasons of the most relevant changes, or to clarify any part of…

IEC 62271-203:2022 specifies requirements for gas-insulated metal-enclosed switchgear in which the insulation is obtained, at least partly, by an insulating gas or gas mixture other than air at atmospheric pressure, for alternating current of rated voltages above 52 kV, for indoor and outdoor installation, and for service frequencies up to and including 60 Hz. This third edition cancels and…
