The Science and Technology Centre includes laboratories providing quality assessment services during the entire oil production and refining process.

Quality control process starts by field testing of the quality of crude oil in facility laboratories, it is continued with the testing of crude oil prepared for refining, the testing of quality of certain processes and intermediate products important for the monitoring and control of operation of refining facilities, and finishes with the quality control of the final refining products and the issuance of a Test Report. The Test Report confirms that the quality of produced fuels is in compliance with the quality required by the national rules and regulations.

Laboratory tests performed as the final quality control, prior to the delivery of fuel to end users, are undertaken in order to ensure the quality of fuel during the transport from the refinery to filling stations and to prevent possible degradation of fuel in transport. These procedures guarantee the quality of fuels produced by the Company.

Raising the level of customer satisfaction to the highest level possible is one of the Company priorities. In order to analyze and monitor customer satisfaction, the Company conducts different customer satisfaction surveys.

Communication between suppliers and customers requires producers and importers to provide information on the environmentally-friendly and safe use of their substances or mixtures – the main instrument in such communication is the Safety Sheet. The safety sheet is a statutory document whose use has been mandatory since 2013.

Compliance with REACH (Registration, Evaluation, Authorization and Chemicals) is a prerequisite for the export of Company products to the European Union. Since a significant part of its products is exported to the European Union market, NIS has undertaken extensive tests and activities with a view to fulfilling its REACH obligations. A total of 14 Company products have been registered as REACH-compliant. This has ensured free marketing and sales of NIS products on the European Union market. Read more

Minor negative impact of product

In order to reduce the environmental impact, NIS produces and sells AdBlue, which is a 32.5% aqueous urea solution that is used to reduce vehicle exhaust gases, i.e. of nitrogen oxides, by converting them into an unharmful gas – N2. AdBlue is stored in a special tank in the vehicle, wherefrom it is injected into the exhaust gas treatment device, the so-called SCR (Selective Catalytic Reduction) system.

Biodegradable lube oils are the lube oils that in contact with the environment shall cause minimal harmful effect. In addition, biodegradable lube oils are produced from renewable resources (vegetable oil). Therefore, since its establishment the Lubricants Department is working on development of “ECO-FRENDLY” range of products – environmentally friendly lube oils. In 2015 the development of a biodegradable product NISOTEC Biotesterol was completed, which is intended for lubricating chain saws. After the completion of laboratory tests also the exploitation – application testing was performed in close cooperation with the customer, by which the formulation was verified. The drafting of technical documentation has also been completed and the production is launched. The product will be distributed and made available to customers at NIS Petrol stations.
