133 new standards came into force in the beginning of April 2022 in the Russian Federation.
There are a group of interstate standards for cereals (technical specifications), heating boilers, gas heaters with forced convection for heating of buildings (domestic and non-domestic purposes), trunk pipeline transport of oil and petroleum products, devices printing in Braille script and others among the above-mentioned documents.
Now we will elaborate on several documents that have come into force for the first time.
GOST R 59634-2021 «Snow safety systems. General specifications» is distributed on the systems of snow safety of pitch roofs.

Elements of the snow safety system for the roofs should be manufactured of the metal resistant to the corrosion, atmospheric and climatic impacts during the whole life cycle according to the document. Materials should not have any defects and foreign inclusions that can worsen the loading-carrying ability. Separate elements of snow safety systems can be manufactured of other materials.
