Testing Laboratory

Testing Laboratory performs testing and measurements in scope of natural environment, including water, wastewater, soils and sludge analyses, emission and immission measurements as well as noise measurements.

Testing Laboratory received the Accreditation Certificate granted by the Polish Accreditation Center – Accreditation Certificate no AB 912, field of testing: acoustics, sample collection, chemistry, physical-chemical properties, general environment – confirming compliance with the requirements of PN-EN ISO/IEC 17025:2005 norm. Polish Accreditation Center is a signatory of International Laboratory Accreditation Cooperation ILAC

Within the scope of accreditation we perform the following:

determination of BOD₅, pH, electrical conductivity in water and wastewater by electrochemical methods,
determination of COD in water and in wastewater by dichromate titration method,
suspended solids determination, in water and in wastewater (method by filtration through glass fibre filters),
determination of phosphorus and general nitrogen in water and wastewater by testing methods,
determination of dry residues and water content in sludges,
hot environments - estimation of the heat stress on working man, based on the WBGT-index,
cold environments – method of appraisal of negative thermal stress based on WCI and IREQ indices,
determination of thermal comfort using calculation of the PMV and PPD indices
lighting of indoor work places,
measurement and assessment of noise exposure in a work environment.

Outside the scope of accreditation we perform:

determination of sodium content in soils, sludges, water, wastewater, dust and other matrices,
determination of organic compounds not encompassed with the scope of accreditation (after coordination with the client) in ambient air (immission), air of the work environment and in waste gases (gas chromatography method).

We are still working on extending our scope of accreditation.

All analyses are performed using high quality chemical agents (POCH, Fluka, Sigma-Aldrich, Riedel-de Haen) and the certified samples and reference materials (Merck, Hamilton, Sigma-Aldrich, Fluka, RTC, Chiron, AccuStandard).

The laboratory owns modern apparatus ensuring high quality of the performed measurements and analyses

Site testing:

portable gas analyzer PG-250A, Horiba, Japan
exhaust-gas analyzer Testo 350, Testo, Germany
automatic gravimetric dust metering device P-10ZA, ZAM Kęty, Poland
semi-automatic gravimetric dust metering device P-10A, ZAM Kęty, Poland
noise level metering devices SVAN 945, vibration level and noise metering device SVAN 948, acoustic calibrator SV30, SVANTEK, Poland
