This International Standard applies to the assessment of lighting equipment related to human
exposure to electromagnetic fields. The assessment consists of the induced internal electric
field for frequencies from 20 kHz to 10 MHz and the specific absorption rate (SAR) for
frequencies from 100 kHz to 300 MHz around lighting equipment.
Included in the scope of this standard are:
– all lighting equipment with a primary function of generating and/or distributing light
intended for illumination purposes, and intended either for connection to the low voltage
electricity supply or for battery operation; used indoor and/or outdoor;
– lighting part of multi-function equipment where one of the primary functions of this is
illumination;
– independent auxiliaries exclusively for the use with lighting equipment;
– lighting equipment including intentional radiators for wireless communication or control.
Excluded from the scope of this standard are:
– lighting equipment for aircraft and airfields;
– lighting equipment for road vehicles; (except lighting used for the illumination of passenger
compartments in public transport)
– lighting equipment for agriculture;
– lighting equipment for boats/vessels;
– photocopiers, slide projectors;
– apparatus for which the requirements of electromagnetic fields are explicitly formulated in
other IEC standards.
NOTE The methods described in this standard are not suitable for comparing the fields from different lighting
equipment.
This standard does not apply to built-in components for luminaires such as electronic
controlgear.

IEC 60364-7-714:2011 applies to the selection and erection of luminaires and lighting installations forming part of an outdoor fixed installation. The origin of the external lighting installation is the supply delivery point of electrical energy by the supply authority or the origin of the circuit supplying the external lighting installation exclusively. The requirements apply to, for example, lighting installations for roads, parks, gardens, places open to the public, sporting areas, illumination of monuments, floodlighting, telephone kiosks, bus shelters, advertising panels, town plans and road signs. The requirements do not apply to: - public street-lighting installations which are part of the public power grid; - temporary festoon lighting; - road traffic signal systems; - and luminaires which are fixed to the outside of a building and are supplied directly from the internal wiring of that building. This second edition cancels and replaces the first edition, published in 1996, and constitutes a technical revision. The major technical changes with respect to the previous edition are listed below: - clause numbering is aligned with present structure of IEC 60364; - additional protection is required in some cases of equipment incorporating lighting; - more stringent requirements regarding IP degree of protection; - introduction of particular requirements for isolation.

ISO 10916:2014 defines the calculation methodology for determining the monthly and annual amount of usable daylight penetrating non-residential buildings through vertical facades and rooflights and the impact thereof on the energy demand for electric lighting. It can be used for existing buildings and the design of new and renovated buildings. ISO 10916:2014 provides the overall lighting energy balance equation relating the installed power density of the electric lighting system with daylight supply and lighting controls (proof calculation method). The determination of the installed power density is not in the scope of this method, neither are controls relating, for instance, to occupancy detection. Provided the determination of the installed power density and control parameters using external sources, the internal loads by lighting and the lighting energy demand itself can be calculated. The energy demand for lighting and internal loads by lighting can then be taken into account in the overall building energy balance calculations: heating; ventilation; climate regulation and control (including cooling and humidification); and heating the domestic hot-water supply of buildings. For estimating the daylight supply and rating daylight-dependent artificial lighting control systems, a simple table-based calculation approach is provided. The simple method describes the division of a building into zones as required for daylight illumination-engineering purposes, as well as considerations on the way in which daylight supplied by vertical facade systems and rooflights is utilized and how daylight-dependent lighting control systems effect energy demand. Dynamic vertical facades with optional shading and light redirection properties are considered, i.e. allowing a separate optimization of facade solutions under direct insolation and under diffuse skies. For rooflighting systems standard, static solutions like shed rooflights and continuous rooflights are considered. The method is applicable for different latitudes and climates. For standard building zones (utilizations), operation times are provided. For detailed computer-based analysis (comprehensive calculation), minimum requirements are specified. To support overall building performance assessment, additional daylight performance indicators on the overall building level are provided.
