Abstract

The territory of the Russian Federation can be divided into areas characterized by varying degrees of hail hazard. Most of them are occupied by territories with a low degree of hail hazard. The southern territories of Russia are located in an elevated hail fallout zone and are an important part of the country’s economy. Roofs and facades of buildings and structures also fall under the influence of hail, which leads them to an inoperable and emergency condition. Facade panels, light openings, roofing, drains, ventilation shafts, parapets fall under the blows of hail. GOST R 57414–2017 “Roofing and waterproofing flexible bitumen-containing and polymer materials (thermoplastic and elastomeric)” describes a method for determining resistance to impact of hail. In accordance with it, an installation for testing roofing materials was prepared. The work of a pneumatic device simulating hail, which will later be called a “HAIL CANNON”, has been studied.
