IEC/TR 62540:2009(E) applies to all stationary lead-acid cells and monobloc batteries for float charge applications (i.e. permanently connected to a load and to a d.c. power supply), in a static location (i.e. not generally intended to be moved from place to place) and incorporated into stationary equipment or installed in battery rooms for use in telecom, uninterruptible power supply (UPS), utility switching, emergency power or similar applications. These batteries are covered by IEC 60896-11, IEC 60896-21 and IEC 60896-22.

This International Standard relates to Flow Batteries used in Electrical Energy Storage (EES) applications and provides the main terminology and general aspects of this technology

This standard establishes the minimum job performance requirements necessary for fire service and other emergency response personnel who perform technical rescue operations.

Withdrawn standard. This recommended practice contains application guidelines and procedures for the interconnection and compatible operation of a SWECS with electric utilities. It addresses the interface between the wind system and the utility and the factors relating to equipment protection, power quality, and the safety of operating personnel and the general public.

Withdrawn Standard

Replace this clause of the RD with the following: 1.1.1 Equipment covered by this standard This Standard applies to UPS, whose primary function for this Standard is to ensure continuity of an alternating power source. The UPS may also serve to improve the quality of the power source by keeping it within specified characteristics. This Standard is applicable to movable, stationary, fixed, and built-in UPS for distribution systems up to 600 V AC.

1.1 These requirements cover small wind turbine systems (WT) and electrical subassemblies. With respect to this standard, small WT are considered to be wind turbines where a user or service person cannot or is not intended to enter the turbine to operate it or perform maintenance. These units are intended for use in stand-alone (not grid-connected) or utility interactive applications. Utility-interactive, grid-tied WT are operated in parallel with an electric power system (EPS) to supply power to common loads.

The technical specifications for, and testing of, the interconnection between utility electric power systems (EPS) and distributed energy resources (DER) are the focus of this standard. It provides requirements relevant to the performance, operation, testing, safety considerations, and maintenance of the interconnection. It also includes general requirements, response to abnormal conditions, power quality, islanding, and test specifications and requirements for design, production, installation evaluation, commissioning, and periodic tests.

This guide describes construction, protection, occupancy features, and practices intended to reduce security vulnerabilities to life and property. Provisions cover security planning, administrative controls, security perimeters, crime prevention through environmental design, security systems, and accessory property. In addition, individual chapters present specific requirements for educational facilities; health care; lodging, multi-dwelling unit buildings, restaurants, shopping centers, retail establishments, office buildings, and industrial facilities.

This standard provides requirements for the application, location, installation, performance, testing, and maintenance of electronic premises security systems and their components. Provisions define the means of signal initiation, transmission, notification, and annunciation; the levels of performance; and reliability.
