Abstract. This paper evaluates the results of selected mechanical properties of outdoor painting systems used in the railway industry and the influence of laboratory weathering (simulation of outdoor conditions) with sunlight, temperature, and moisture on the change of these properties. The impact of the above-mentioned weather parameters, particularly solar radiation, was briefly described on the degradation of coating systems of weathering on selected mechanical properties such as hardness, resistance to gradual deformation (cupping test), and adhesion (fracture strength) was evaluated. The tests were carried out at the Railway Institute, Materials and Construction Laboratory, using two weathering methods: ISO 16474-2 [1] and the in-house method described in DN 001/08/A2/16 paragraph 4.1.8 [2].
