GOST R 59403-2021 «Professional cleaning services – cleaning services». Green cleaning. General technical requirements. The standard applies to ecological cleaning services on real estate objects, territories and vehicles. The document establishes the safety requirements for these services for the life and health of people, animals, plants and environmental protection.
According to the standard, the complete biodegradability of surfactants that make up synthetic detergents (laundry detergents) used for washing textile materials and for cleaning must be at least 60% in terms of carbon dioxide or at least 70% in terms of total organic carbon.
Products made of textile materials for ecological cleaning must be hand and machine washable at temperatures from 90 ° C to 95 ° C.
GOST R 58458-2020 «Swimming pools. General specifications» establishes requirements for the technical condition, infrastructure parameters, the environment during the operation of swimming pools.
The water temperature in the pools for preschool children should be from 30 to 32 ° C; in
training and health-improving pools - from 26 to 29 ° С.
The illumination of the water surface of the baths of the health-improving and sports pools is from 200 to 600 lux.
In indoor swimming pools, the noise level should not exceed 82 dBA during training sessions and the provision of physical culture and health services, and during competitions - no more than 110 dBA.
In the baths of the pools, a technological slope of the bottom should be provided, intended for draining water, directed to the places of its release into the drain water intake device. The slope value should be taken in the range from 1% to 4%.
Along the walls along the entire perimeter of the pool baths, the depth of which exceeds 1.2 m, there is a ledge for relaxation with a width of 0.10 to 0.15 m.
GOST R 34697-2020 «End valves and disconnecting valves. General specification. General technical conditions» apply to devices designed for controlled mechanical blocking of brake, feed and air lines of a railway rolling stock unit.
According to GOST, the operating temperature range of the ambient air, which does not interfere with the operation of the cranes, is from minus 60 ° C to plus 60 ° C.
Over the entire operating temperature range, at a pressure of (0.60 ± 0.02) MPa, the turning force applied to the end of the valve handle should be no more than 245 N.
The end valve gate must be sealed at a maximum (0.98 ± 0.02) MPa and a minimum (0.1 ± 0.02) MPa compressed air pressure and at the limiting values of operating temperatures.
The assigned service life of end and disconnected valves is at least 32 years.
