Light intensity tests

The fundamental requirement regarding the working environment is to ensure an appropriate level of illuminance. Illumination intensity in the work environment (and not only) is defined as the average value of illumination on a section of a previously defined work plane. The value of the average illuminance must be appropriate to the nature of the work and the spatial conditions.

The work plane is defined as the actual or imaginary plane on which the work is performed. Usually, it is defined as the plane at a height of 0.85 m from the floor level. For aboveground works and open spaces, the working plane is defined at the floor/ground level.

What is the impact of lighting intensity on human health?

Inadequate lighting has a negative impact on the human visual perception.

Too low value of the intensity results in the lack of vision of objects and co-workers, which may cause accidents at work and a significant reduction of efficiency.

Too intense light can cause dizziness, headaches, and loss of concentration. It also affects the malaise and disrupts the daily cycle.


ENVILAB-EKO measuring equipmenta

Our ENVILAB-EKO workplace environment laboratory conducts measurements of illuminance using a L100 luxmeter. Thanks to this device, we can determine the illuminance in the range from 5 to 10,000 lx, using the direct measurement method. Measurements are conducted according to the reference document: PN-83/E-04040.03, EV-PB-2, edition 1, 02/01/2017. 

From the performed measurements, the work environment laboratory ENVILAB-EKO calculates the uniformity of lighting and compares the obtained values with the values from the applicable standards.

We make measurements throughout entirety of Poland.

Legal provisions

Standards and legal provisions specifying how the conducted illuminance tests are to be conducted:

Measurements of lighting intensity in the work environment performed by the ENVILAB-EKO laboratory are conducted on the basis of the guidelines set out in §26 section 2 of the Regulation of the Minister of Labor and Social Policy of September 26, 1997, on general provisions on occupational health and safety (consolidated text: Journal of Laws of 2003, No. 169, item 1650, as amended).
