Quality laboratory services

The laboratory was founded in 1969 in order to test the quality of oil and petroleum products in the production processes of NIS.


Since 2009, the laboratory has been transformed into a commercial laboratory that offers testing services for oil, gas, semi-products, commercial oil derivatives, oils and lubricants at the market.


In order to satisfy the needs of internal and external service providers, which require the recognition of the competence of the laboratory to carry out testing activities in the field of petroleum derivatives, including fuels, lubricants and solvents, as well as in the field of chemical products, the Downstream Laboratory received accreditation granted by the Accreditation Body of Serbia (ATS). The laboratory works in accordance with the EN ISO/IEC 17025 standard and has adopted all technical and safety requirements. It is equipped with modern testing equipment that complies with the specifications relevant to the tests.


The laboratory is accredited for 269 testing methods.
