This part of IEC 60079 specifies the requirements for the design, construction, testing and marking of electrical equipment and Ex Components with type of protection increased safety “e” intended for use in explosive gas atmospheres. Electrical equipment and Ex Components of type of protection increased safety “e” are either: a) Level of Protection “eb” (EPL “Mb” or “Gb”); or b) Level of…

ISO 17509:2016 specifies requirements for torque transmitters to be used in oral implantology in conjunction with a dental handpiece as an accessory in the placement of dental implants and the further manipulation of connecting parts in the craniofacial area. ISO 17509:2016 applies to torque transmitters used for placement and for removal in the oral cavity of the patient which are connected to…

IEC 62548:2016 sets out design requirements for photovoltaic (PV) arrays including DC array wiring, electrical protection devices, switching and earthing provisions. The scope includes all parts of the PV array up to but not including energy storage devices, power conversion equipment or loads. An exception is that provisions relating to power conversion equipment are covered only where DC safety…

IEC TS 62257-9-3:2016(E) specifies the general requirements for the design and the implementation of the interface equipment within the user's installation which connects to a microgrid or the generating part of a standalone system. It applies to simplified user's interfaces (distribution board) in electrical installations with maximum power of 500 VA in decentralized rural…

IEC 61975:2010+A1:2016 applies to system tests for high-voltage direct current (HVDC) installations which consist of a sending terminal and a receiving terminal, each connected to an a.c. system. The tests specified in this standard are based on bidirectional and bipolar high-voltage direct current (HVDC) installations which consist of a sending terminal and a receiving terminal, each connected…

IEC 62873-3-1:2016(E) applies to RCDs equipped with screwless terminals, for current not exceeding 20 A primarily suitable for connecting unprepared (see 3.5) copper conductors of cross-section up to 4 mm2. This part of IEC 62873 cannot be used alone but it is intended to be applied together with an RCD product standard (IEC 61008-1 or IEC 61009-1) if an RCD is equipped with screwless terminals.

IEC 62873-3-2:2016(E) applies to RCDs equipped with flat quick-connect terminations consisting of a male tab (see 3.2) with nominal width 6,3 mm and thickness 0,8 mm, to be used with a mating female connector for connecting electrical copper conductors according to the manufacturer's instructions, for rated currents up to and including 16 A.

ISO 1219-3:2016 supplements ISO 1219-1 and ISO 1219-2 by specifying rules for the generation and combination of symbols of connectable components in circuit diagrams. Using these symbols, the design envelope and piping can be reduced.

IEC 61800-5-1:2007+A1:2016 It specifies requirements for adjustable speed power drive systems, or their elements, with respect to electrical, thermal and energy safety considerations. It does not cover the driven equipment except for interface requirements. It applies to adjustable speed electric drive systems which include the power conversion, drive control, and motor or motors. Excluded are…

IEC 61800-5-1:2007+A1:2016 spécifie les exigences pour les entraînements électriques de puissance à vitesse variable, ou leurs éléments, en ce qui concerne les considérations de sécurité électrique, thermique et énergétique. Elle ne couvre pas l'équipement entraîné, à l'exception des exigences pour les interfaces. Elle s'applique aux systèmes d'entraînement électrique à…
