IEC 63202-1:2019 describes procedures for measuring the light-induced degradation (LID) of crystalline silicon photovoltaic (PV) cells in simulated sunlight. The magnitude of LID in a crystalline silicon PV cell is determined by comparing maximum output power at Standard Test Conditions (STC) before, and after, exposure to simulated sunlight at a specified temperature and irradiance. The purpose…

l'IEC 63202-1:2019 décrit les procédures pour la mesure de la dégradation induite par la lumière (LID, light-induced degradation) des cellules photovoltaïques (PV) au silicium cristallin sous éclairement solaire simulé. L'amplitude de la dégradation induite par la lumière dans une cellule photovoltaïque au silicium cristallin est déterminée en comparant la puissance de sortie maximale…

This document reviews the methodologies or analytical models that have been used to develop the strength and stiffness of structural glued laminated timber (glulam) from the characteristic properties of lumber laminations. The review is limited to the methodologies used in Europe, the USA, Australia/New Zealand, and Canada as they represent different fundamental philosophies in these areas. As a…

This document specifies requirements for the design, fabrication, inspection and testing of large transportable vacuum-insulated cryogenic vessels of more than 450 l volume, which are permanently (fixed tanks) or not permanently (demountable tanks and portable tanks) attached to a means of transport, for one or more modes of transport. This document applies to large transportable vacuum-insulated…

Le présent document spécifie une méthode pour la détermination du taux de ventilation applicable aux cigarettes.

This document specifies a visual method for assessing the porosity of the machined surface of aluminium alloy castings. The method does not apply to assessing porosity shown on radiograms.

This document specifies a method for the determination of ventilation which is applicable to cigarettes.

This document specifies test conditions and test procedures for determining the performance characteristics of air source heat pump water heaters for space heating with electrically driven compressors with or without supplementary heater. The purpose of this document is to rate the performance of the heat pump water heaters for space heating with no operation of any supplementary heater. In the…

This document specifies how to measure and report the shooting time lag, shutter release time lag, shooting rate and start-up time lag for digital still cameras, including camera modules in phones and tablet computers. It includes a method that uses control signals inside the digital still camera and a method that determines the timing values without requiring access to the inside of the digital…
