The Electrical lighting for rolling stock European Standard specifies design criteria for electrical lighting illumination levels within the interiors public transport railway rolling stock under all operating conditions. It is important to consider the specific tasks and safety requirements when designing a lighting system.

The lighting design should not only provide task-related illumination, but also create a pleasant and comfortable visual environment.

To ensure tasks that require particular attention, it is important to specify the minimum lighting levels.

Lighting equipment related to electromagnetic fields

This International Standard covers the assessment of lighting equipment that is related to humans Exposure to electromagnetic fields. The assessment includes the induced internal electricity

Field for frequencies between 20 kHz and 10 MHz. The specific absorption rate (SAR), is also available.

Frequency ranges from 100 kHz up to 300 MHz in the vicinity of lighting equipment.

These are included in the scope of the standard:

All lighting equipment that has the primary function of producing and/or dispersing light

Designed for illumination and for use with the low voltage.

Use indoor or outdoor for electricity supply and battery operation

Multi-function equipment lighting is one of its primary functions.

- Independent auxiliaries for use only with lighting equipment

- Lighting equipment, including intention radiators for wireless control or communication.

These items are not included in the scope of this standard:

Lighting equipment for airfields and aircraft;

- Lighting equipment for roads vehicles (except for lighting for illumination of passengers)

Public transport compartments

Lighting equipment for agriculture

Lighting equipment for boats/vessels

- photocopiers, slide projectors;

- Apparat for which the electromagnetic field requirements are specifically formulated

Daylight and energy demand for lighting

ISO 10916.2014 describes the method for calculating the amount of daylight that can penetrate non-residential buildings via rooflights or vertical facades. It also explains the impact on electric lighting demand. This can be used to design new or renovated buildings as well as existing buildings. ISO 10916.2014 is an international standard that calculates the total lighting energy balance. It relates the installed power density of electric lighting systems with daylight supply and lighting controls (proof calculation). This method does not include the determination of the installed energy density. It also doesn't cover controls related to occupancy detection. The internal loads by lighting can be calculated once the control parameters are determined using external sources. In order to calculate the total building energy balance, the energy required for lighting and the internal loads caused by lighting can be included. These include heating, ventilation, climate regulation and control (including cool and humidification); as well heating the domestic hot water supply of buildings. A simple table-based calculation is used to estimate the daylight supply and rate artificial lighting control systems that are daylight-dependent. 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. The dynamic vertical facades can be equipped with light redirection and shading options. This allows for separate optimization of facade solutions under direct sunlight and under diffuse skies. Standard rooflighting systems can be characterized by static solutions such as shed rooflights or continuous rooflights. This method can be used in different climates and latitudes. Operation times are given for standard building zones (utilizations). Minimum requirements are required for computer-based analysis (comprehensive calculations). Additional daylight performance indicators at the building level can be used to support overall building performance assessment.

Reflecting surfaces for luminaires

This European standard covers the optical performance of untreated and coated materials in sheet or strip form. It can be used as a plane, formed or preformed reflector. These include: a) Untreated base materials such as: 1) Aluminium, 2) Steel, 3) Plastic, and 4) Glass. b) Surface treated materials include: 1) polished materials; 2) anodised and 3) vacuum-metallised materials; 4) painted materials; 5) multilayer systems. Fluorescent materials are not covered by this European Standard.
