Laboratory Testing of Flammable Materials

ISO/IEC 17025 Accredited Laboratory

Many industrial processes include combustible materials in the form of liquids, vapours, mists, gasses, dusts, fibres and/or flyings. Fiditas experts provide solutions to potential problems that can occur during technological treatment of such hazardous materials. This technological treatment may involve different operations, such as transport, storage, handling, mixing, or unique patented industrial methods, all of which can generate explosive atmospheres which may explode in the presence of the ignition source.

Any such explosion may cause huge human losses and devastate facilities and surroundings, having potential hazardous effect to the environment. Companies operating hazardous materials are exposed to additional risks, involving the negative publicity and the loss of production, not to mention individual responsibilities of the managing personnel.    

Combustible materials can normally be found in gas distribution, petroleum refining and distribution, petrochemical, defense, wastewater, pharmaceutical, mining, food, grain, printing, research and test facilities, cement production, off shore rigs, petrol filling stations, chemical industry, shipyards, furniture production as well as in a variety of specialist manufacturing and processing plants.

To avoid unwanted scenarios there is essential need to apply effective safety measures. Such safety measures are identified in the process of Explosion Risk Assessment, as defined in Directive 1999/92/EC, also known as ATEX 153 (or DSEAR in UK). Explosion Risk Assessment requires deep understanding of several international and national safety standards and codes, industrial guides and rules and competency in different fields of science, including fluid dynamics, finite elements methods, computer aided design… Experience of person performing the Explosion Risk Assessment is another key element to achieve reliable results and define effective explosion safety solutions.

Reliable and effective explosion safety solutions cannot be obtained if physical and chemical properties of combustible materials are not known. Fiditas provides  integrated set  of laboratory tests performed on combustible materials in compliance with current editions of international standards. This integrated set of tests includes determination of a full spectrum of material properties which allows us to define its flammability and explosiveness. By understanding and adopting process improvement and lean principles, Fiditas laboratory achieves more efficient workflows by eliminating steps, reducing waste, and producing higher reliability results more quickly than ever before.

Fiditas laboratory is capable to perform tests in order to obtain following material properties (current standard editions used):

  • Material characteristics – Combustible dusts test methods (ISO/IEC 80079-20-2)
  • Determination of minimum ignition energy of dust/air mixtures (EN 13821)
  • Determination of the auto ignition temperature of gases and vapours (EN 14522)
  • Determination of the maximum explosion pressure pmax of dust clouds (EN 14034-1)
  • Determination of the maximum rate of explosion pressure rise (dp/dt)max of dust clouds (EN 14034-2)
  • Determination of the lower explosion limit LEL of dust clouds (EN 14034-3)
  • Determination of the limiting oxygen concentration LOC of dust clouds (EN 14034-4)
