Accredited measurement and assessment of environmental and occupational physical factors

Measurement of environment noise immission

• noise immission measurement in protected area from road and railway traffic
• noise immission measurement in protected area from other noise sources

Measurement of occupational noise immission

• noise immission measurement at workplaces of workgroups (nonspecific noise effects)

Measurement and determination of occupational noise exposure

• Measurement and determination of occupational noise exposure for the nominal day (shift) (specific noise effects)

Measurement of vibration

• measurement of vibration in defined places or in places of transmission to human body
• measurement of vibration in buildings

Vibration measurement and evaluation of human (worker) exposure

• measurement and evaluation of human exposure to hand-transmitted vibration for the nominal day
• measurement and evaluation of human exposure to whole-body vibration for the nominal day

Measurement of sound power level

• measurement and determination sound power level of noise source – survey method according to the standard EN ISO 3746

Measurement of electromagnetic field strength related to human exposure and evaluation of human exposure to electromagnetic fields

• measurement of static magnetic field flux density
• magnetic flux density (magnetic field strength) measurement
• electric field strength (power density) measurement
• determination (calculation) of current density induced in human body exposed to low frequency electric and magnetic field
• evaluation of tissue electric stimulation effect (simultaneous exposure to fields of different frequencies in frequency range below 10 MHz)
• evaluation of tissue thermal effect (simultaneous exposure to fields of different frequencies in frequency range above 100 kHz )

Measurement of lighting
