Accredited laboratory scope (ISO/IEC 17025)
Physico-chemical analyses and sampling in the fields of air, emission measurements, microclimatic conditions, noise, artificial lighting and vibration.
Emissions from stationary sources
Sampling, determination of emission components, TOC/VOC, particulates, NOx, CO, SO₂, O₂ and related parameters.
Workplace and indoor air
Dust, organic substances, chemicals, aerosols, fibres and operational exposure.
Microclimate
Temperature, pressure, humidity and air velocity in the workplace environment.
Lighting
Artificial lighting in indoor and outdoor environments.
Vibration
Hand-transmitted vibration and whole-body vibration for hygiene and occupational health and safety purposes.
Noise
Noise in workplace and non-workplace environments according to applicable methods.
The full list of methods and analysts is in the annex to the certificate of accreditation (PDF).
The laboratory uses analysers, sampling equipment, acoustic and vibration instruments, lux meters, pumps and laboratory facilities for sample preparation and evaluation.
