There are many types of sprinklers that have been approved for use in fire protection. Differences in design, and in particular their basic element, which is the deflector, have an impact on the parameters of the spray produced by them. The main objective of the work was to examine these parameters, and above all the intensity and uniformity of water distribution, based on the PN-EN 12259-1:2005 standard, and then to analyze the obtained results in terms of the extinguishing effectiveness of the tested sprinklers. The results are presented in tabular and graphical form. Based on the results obtained, a number of conclusions were formulated. It was also found that some of the tested sprinklers do not meet the minimum requirements contained in the applicable standards.Among the systems used for extinguishing fires in rooms, automatic sprinkler systems, which are permanently connected to the protected facility and use water as an extinguishing agent, are very popular.
