This document specifies minimum requirements for the material, design, construction, workmanship, examination and testing at manufacture of refillable welded steel cylinders for the sub-atmospheric pressure storage of liquefied and compressed gases. It only applies to the cylinders themselves, irrespective of the materials contained therein (e.g. adsorbents, media, materials and/or gases) and…

This document establishes general principles for measuring the uniformity of furnace exposure of samples tested in accordance with the requirements of ISO 834‑1. This document specifies the type and location of instrumentation used to measure the temperature, velocity and oxygen content near the surface of simulated test samples. The surface of the simulated sample facing the furnace is gypsum…

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…

IEC 60068-2-85:2019 demonstrates the adequacy of specimens to resist dynamic loads without unacceptable degradation of its functional and/or structural integrity when subjected to the specified vibration test requirements as defined by a time history (long time history replication). These can either be recorded in measurement exercises or generated artificially. In both cases, this method allows…

L'IEC 60068-2-85:2019 a pour objet de démontrer la capacité des spécimens à résister aux charges dynamiques sans dégradation inacceptable de leur intégrité de fonctionnement et/ou de structure, lorsqu'ils sont soumis aux exigences d'essais de vibrations spécifiées, définies par un accélérogramme (reproduction des vibrations dans le temps). Ces vibrations peuvent être enregistrées…

ISO/IEC 14543-5-101:2019 (E) enables a media connection, resource sharing and co-operation among computers, home appliances and consumer electronics using remote access (RA). Also, users and devices can share and control media resources. This document specifies: • an IGRS remote media access profile based on the IGRS RA core protocol and the IGRS RA platform protocol, and • application rules…

IEC 61158-6-19:2019 provides common elements for basic time-critical and non-time-critical messaging communications between application programs in an automation environment and material specific to Type 2 fieldbus. The term “time-critical” is used to represent the presence of a time-window, within which one or more specified actions are required to be completed with some defined level of…

L’IEC 611586-19:2019 fournit des éléments communs pour les communications de messagerie prioritaires et non prioritaires élémentaires entre les programmes d’application des environnements d’automatisation et le matériel spécifique au bus de terrain de type 19. On utilise le terme "prioritaire" pour traduire la présence d’une fenêtre temporelle, à l’intérieur de laquelle il est exigé qu’…

IEC 61158-6-23:2019 provides common elements for basic time-critical and non-time-critical messaging communications between application programs in an automation environment and material specific to Type 2 fieldbus. The term “time-critical” is used to represent the presence of a time-window, within which one or more specified actions are required to be completed with some defined level of…
