Lighting measurement is a test carried out in workplaces to determine the adequacy of lighting levels. This test measures whether the business has the correct lighting for the sector it operates in and the work being done. The measurement results must fall within the limit values specified for the relevant application area.
Workplace lighting measurements use the reference values specified in the TS EN 12665, TS EN 12464-1, TS EN 12464-2, ISO 8995-1 and ISO 8995-3 standards. The relevant standard sets out the lighting requirements for work areas.
Measurements are carried out according to the measuring points and methods described in TS EN 12464-1 for indoor areas, TS EN 12464-2 for outdoor work areas and TS EN 13201-4 for road lighting. All illuminance measurements use the lux (lx) unit; measurements must be made with a lux meter with valid calibration.
Workplace lighting obligations are governed by the Occupational Health and Safety Law No. 6331 and the Regulation on Health and Safety Measures to Be Taken in Workplace Buildings and Annexes, which is based on this law. The minimum illuminance levels required for working environments are determined from the tables in the relevant standards.
