Accredited Indoor Air Quality Testing After Renovation
Spaces designated for permanent human occupancy — offices, schools, hospitals, retail premises — may contain elevated concentrations of chemical substances emitted from paints, adhesives, flooring and insulation materials following renovation or fit-out works. Polish OHS regulations and construction standards require confirmation that concentrations of these substances do not exceed permissible values before spaces are handed over for occupancy. OIKOS performs measurements under PCA accreditation No. AB 934 (PN-EN ISO/IEC 17025) — results accepted by building supervision authorities and the State Sanitary Inspectorate.
Why OIKOS for Indoor Air Acceptance
Four reasons our indoor air quality testing stands out — one report covers the full handover scope:
- Results accredited under PN-EN ISO/IEC 17025 (AB 934) — accepted by building supervision authorities and the State Sanitary Inspectorate
- A single commission covers formaldehyde (HCHO), residual solvent vapours, and acrylonitrile — one report for the full scope
- Test report ready for inclusion in technical handover documentation or submission to the property manager
- Over 35 years of environmental testing experience and more than 1,000 clients served
Formaldehyde, VOCs & Acrylonitrile — Pre-Handover Verification
OIKOS performs accredited measurements of formaldehyde (HCHO), volatile organic compounds (VOCs) and acrylonitrile concentrations in indoor air. Sampling and analysis are conducted according to applicable standard methods within the scope of AB 934 accreditation, granted by the Polish Centre for Accreditation.
Results are presented in a report that compares measured concentrations against applicable normative limit values. This protocol constitutes a document ready for submission to the building supervision inspectorate or for inclusion in the as-built documentation of the facility.
OIKOS has been conducting environmental tests since 1988. Over more than 35 years we have served more than 1,000 clients in the construction, development and public sectors — over two thirds return for subsequent projects.

FAQ
Indoor Air Acceptance Questions
When is indoor air quality testing required after renovation?
Measurements are required or recommended before spaces designated for permanent human occupancy are handed over after construction or fit-out works. This obligation arises from OHS regulations and sanitary-epidemiological requirements.
What substances are measured in indoor air?
The standard scope covers formaldehyde (HCHO), residual solvent vapours (VOCs) and acrylonitrile. Depending on the materials used, the scope may be extended to other substances — please inform us at the time of placing your order.
How long after renovation should testing be carried out?
It is recommended to wait at least several days after finishing works for conditions in the space to stabilise. The exact time depends on the materials used and ventilation conditions. Our specialists will advise you on the optimal timing when you place your order.
