VOC Measurements

The definition of volatile organic matter is shortly known as VOC. VOC stands for Volatile Organic Compounds. Volatile organic substances are chemicals that harm human health and nature. In order to reduce the amount of VOC emissions released to the atmosphere and to protect human health, various regulations are made by local and foreign organizations and standards are set.

Volatile organic substances are carbon-containing components that generally contribute to photochemical reactions in the atmosphere. Such chemical components arise from petroleum refineries, painting activities, fuel storage and loading processes, solvent cleaning and many other reasons. Such pollutants are also commonly found in indoor air. VOC concentrations are measured over a wide range up to 50-1000 μg per cubic meter.

Since people spend most of the day indoors, such as home or office, long-term exposure to VOCs raises a condition called building syndrome. In these environments, wall coverings, new furniture, VOC containing gas-emitting photocopiers and similar office devices are the source of volatile organic materials. Well-designed air conditioning and ventilation systems are effective in reducing VOC emissions in confined spaces.

There is evidence that cancer risk increases with prolonged exposure to volatile organic substances.

VOCs that spread to nature also mix with soil and surface waters. Airborne VOCs are the main cause of increased air pollution. Leafy plants are therefore very damaged. People's respiratory system is therefore irritated.

In our country, during the harmonization efforts in the process of accession to the European Union, directives issued in this direction were included in our current legal arrangements.

Our company also performs VOC measurements within the scope of gas measurements. In these studies relevant legal regulations, standards and test methods published by local and foreign organizations. A few standards considered in these studies are:

  • TS EN ISO 11890-1 Paints and varnishes - Determination of the content of volatile organic compounds (VOC) - Part 1: Difference method
  • TS EN ISO 11890-2 ... Chapter 2: Gas chromatography method

 

In the meantime, our organization, ÖSAS Accreditation Agency, Accredited according to TS EN ISO / IEC 17025 standard.
