"DONSTROYTEST” LTD. REGIONAL TESTING CENTRE

Organization and carrying out of fire tests of building structures, products and materials

• determination of the fire resistance limits of building construction elements:
    - divisions and coverings of buildings and structures (including those made of cast reinforced concrete);
    - walls and partitions, including the glassed ones;
    - flights of the stairs, landings of staircase and their elements;
    - beams, collar beams, frames, arches and truss elements;
    - columns;
    - balconies and corridors.
  
• determination of fire resistance of:
    - doors, gates and hatches;
    - fire windows;
    - fire and smoke curtains (screens);
    - air pipes and fire ventilation dampers;
    - cable passages and passages of plastic pipes;
    - cable lines and their components;
    - suspended ceilings.
  
• determination of fire resistance capability of fire-resisting finishes and veneers of:
    - load-bearing metallic structures;
    - load-bearing reinforced-concrete structures.
  
• determination of an indicator of fire propagation along the structures:
    - along vertical structures (columns, exterior and interior walls, partitions, walls of stairwells, fire barriers, etc.);
    - along horizontal structures (collar beams, beams, divisions, flights of the stairs and stairs landings, suspended ceilings, air pipes, pipelines, etc.).
  
• determination of coefficients of intumescence of fire-resistant coatings;
  
• determination of a group of fire retardant efficiency of fire-retardant materials for the wood;
  
• determination of a group of not easily combustible and flammable solid substances and materials.
