1 Scope This International Standard gives requirements for the Performance and safety of stand-alone gas mixers intended for medical use and intended for connection to a medical gas supply System. Rationales for some of the requirements are given in annex B. This International Standard does not apply to a) blocks of flowmeters with separate controls for the flow of each gas; b) gas mixers…

1 SCOPE 1.1 Except as described in Clause 1.7, these minimum requirements cover single and double wall cylindrical steel, non-pressure tanks of the horizontal type that are used for the underground storage of flammable liquids and combustible liquids, that are compatible with the material of construction. 1.2 These minimum requirements cover double wall tanks with provision for leak detection…

1 SCOPE 1.1 This Standard provides minimum requirements for primary containment leak detection that uses quantitative assessment of physical characteristics to detect leaks in the primary containment. 1.2 These requirements do not cover qualitative nonvolumetric leak detection devices. 1.3 The requirements of this Standard apply to newly-manufactured products. The requirements of this…

1 DOMAINE D’APPLICATION 1.1 La présente norme comprend les exigences minimales relatives à la détection des fuites dans une enceinte de confinement primaire. Cette détection s’appuie sur une évaluation quantitative des caractéristiques physiques. 1.2 Ces exigences ne touchent pas les dispositifs de détection des fuites non volumétriques qualitatives. 1.3 Les exigences de la présente norme s’…

1 SCOPE 1.1 This Standard provides minimum requirements for primary containment leak detection that uses qualitative characteristics to detect leaks in the primary containment. NOTE: Depending on the design of the tank system, and the capabilities of the leak detection devices, leaks from the tank alone, and/or from other parts of the tank system, may be detected. 1.2 Nonvolumetric leak…

1 DOMAINE D’APPLICATION 1.1 La présente norme comprend les exigences minimales relatives à la détection des fuites dans une enceinte de confinement primaire. Cette détection s’appuie sur l’évaluation qualitative des caractéristiques. REMARQUE : Selon la conception du système de stockage, et les capacités des dispositifs de détection des fuites, les fuites provenant du réservoir seulement, ou…

1 Scope This part of IEC 61000 is concerned with the limitation of voltage fluctuations and flicker impressed on the public low-voltage system. It specifies limits of voltage changes which may be produced by an equipment tested under specified conditions and gives guidance on methods of assessment. This part of IEC 61000 is applicable to electrical and electronic equipment having an input…

IEC TR 62511:2014(E) provides guidelines in planning and design of the interconnected power system (IPS) and consequently achieve the delivery of reliable supply service. The guidelines for the design of interconnected power systems within this document will enhance system reliability, mitigate many of the adverse impacts associated with the loss of a major portion of the system or unintentional…

IEC PAS 80005-3:2014(E) describes low voltage shore connection (LVSC) systems, on board the ship and on shore, to supply the ship with electrical power from shore. This PAS is applicable to the design, installation and testing of LVSC systems and addresses: - LV shore distribution systems; - shore-to-ship connection and interface…

IEC 60335-2-90:2006+A1:2010+A2:2014 The safety of microwave ovens with a cavity door intended for commercial use, their rated voltage being not more than 250 V for single-phase appliances connected between one phase and neutral and 480 V for other appliances. It also deals with the safety of microwave ovens without a cavity door and with transportation means that are intended for commercial use…
