Laboratory analysis

Laboratory(definite) testing and analysis

       As already mentioned before, the company performs the assessment of performance for combustion appliances according to construction Regulation and gas European directive.
       The company’s laboratories perform heat and emission measurements for determining the technical and operational features of the solid and liquid fuel and gas appliances, as well as primary testing of the fire safety.
       The laboratory performs also testing for current and production control of the above appliances.
       We offer determination of the following technical and operational characteristics and parameters:
  • Fire safety – determining the safety distances to flammable materials;
  • Combustion products emissions – determined in the output gases:
    • oxygen,
    • carbon dioxide
    • carbon monoxide,
    • nitrogen oxides,
    • organic gases,
    • dust.
  • Determination of hazardous substances;
  • Surface temperature of the controls during appliance operation;
  • Smoke gases temperature;
  • Testing of boilers at double maximum service pressure;
  • Heat output:
    • total heat output,
    • boiler heat output,
    • space heating output .
  • Energy efficiency – efficiency of the appliance,
  • Flue gas mass flow in g/s emitted by the appliance.
