In-situ measurements

In situ measurements

  • In situ measurements of road lighting installations according to EN 13201: 2016 and Royal Decree-Law1890/2008. 
  • In situ tunnel measurements according to UNE-CR 14380: 2007 and CIE 88: 2004.
  • Tests according to UNE-EN_12198-1: 2008 standard. Machine safety. Assessment of risks caused by the radiation emitted by machines.
  • Risk assessment for ultraviolet, blue and infrared radiation at workplaces.
  • Evaluation of interior lighting installations according to the UNE-EN_12464-1: 2012 standard. Lighting of workplaces. Part 1: Indoor Workplaces.
In situ measurements of road lighting installations according to EN 13201: 2016 and Royal Decree-Law1890/2008, Regulation of energy efficiency in outdoor lighting installations 

Measurements of the parameters that define an external lighting installation such as: average luminance, global and longitudinal uniformity, veil luminance, disturbing glares (threshold intensity TI), glare index (glare rating GR), vertical and horizontal illuminance and surrounding lighting (surrounding ratio SR).
In situ measurements in tunnels

In situ measures in tunnels to evaluate the different areas of a tunnel following the indications of the following guides and regulations: 

  • CIE 88: 2004 Guide for lighting road tunnels and underpasses.
  • Royal Decree-Law 635/2006, of May 26, on minimum safety requirements in State Highway tunnels.
  • UNE-CR 14380: 2007 IN Lighting applications. Tunnel lighting. Valid. Issue date 2007-09-26.

These publications define the lighting parameters that each of the different zones of a tunnel must meet: Access zone, threshold zone, transition zone, interior zone, exit zone and also the L20 in the threshold zone.

Luminance is the key parameter to measure in tunnel lighting and at candelTEC we have the appropriate equipment for these measurements, in addition to extensive experience on that.


Evaluation of indoor lighting installations according to UNE-EN_12464-1: 2012 standard. Lighting of workplaces. Part 1: Indoor Workplaces.

Measurements of the parameters established by the standard for workplaces such as: Average illuminance, illuminance uniformity, UGR, color rendering index (CRI) and color temperature.

Tests according to UNE-EN_12198-1: 2008 standard. Machine safety. Assessment of risks due to radiation emitted by machines

Optical radiation measurements [200 - 1100] nm at the points of maximum radiation in the accessible parts of the machines and at distances determined by the standard.

This standard also establishes different measurement conditions depending on the risk to be evaluated.

Finally, it allows the assignation of a category (0, 1 or 2) to the machine, which determines the type of personal protective equipment necessary to operate the machine and the conditions required to do so.
