Car upholstery is a dominant part of interiors of various cars and can significantly contribute to the spread of fire because it belongs to flammable polymer materials. Statistics indicate car fires caused by a cigarette due to smoker's negligence. Picking the right material can mitigate the effects caused by fire, influence the damage to the property and even save life. The diploma thesis deals with evaluation of car upholstery as to fire protection and safety. Car upholstery whose top layer was based on faux leather, leather and polyester textiles was tested. Samples were tested in a new condition without modifications and subsequently subjected to modification by aging simulation and abrasion. Newspaper method (a method without a norm) and smouldering cigarette method pursuant to norm STN EN 1021-2 (2006) were used. In terms of the overall evaluation, the best results were reached by fine leather when it comes to non-textile upholstery material and multi-layer polyester knitted fabric when it comes to textile materials. Modification by abrasion had bigger effect on evaluation criteria compared to the aging simulation.
