2. Direct-fired heaters/vessels
3. Boilers designed to produce hot water at temperatures above 110 °C, or steam t a gauge pressure above 0.05 MPa
4. Piping and valves designed for compressed, liquefied, and pressure-dissolved gases and vapors, as well as for liquids, and used for working media of groups 1 and 2
5. Components (assemblies) of equipment and associated parts and accessories designed to withstand pressure above 0.05 MPa
6. Indicating and safety devices, excluding devices classified as measuring instruments

5. Equipment specially designed for use on sea and river vessels, other floating facilities, and underwater applications
6. Braking equipment for rolling stock of railways, motor vehicles, and other means of transport
7. Pressure vessels specifically designed for use on aircraft and other flying vehicles
8. Equipment for defense purposes
9. Parts of machinery that are not independent pressure vessels (casings of pumps or turbines, cylinders of steam, hydraulic, internal combustion engines, and air machines and compressors)
10. Single-person medical pressure (hyperbaric) chambers
11. Equipment with aerosol dispensers

13. Enclosures and casings for electric power transmission system components (power and communication cables) operating under excess pressure
14. Equipment manufactured from non-metallic flexible (elastic) shells
15. Exhaust or intake gas noise mufflers (silencers)
16. Containers or siphons for carbonated beverages
17. Water supply, distribution, and drainage networks for water at a temperature of 110 °C or less, as well as penstocks in hydroelectric power plants and their associated fittings
18. Heating appliances and pipelines in water-based heating systems of buildings and structures
19. Equipment and its components for supplying gaseous fuel (compressed natural gas, liquefied petroleum gas (or liquefied hydrocarbon gas), liquefied natural gas, fuel-grade dimethyl ether) to engines, specifically designed for use in wheeled vehicles
20. Pipe support and hanger systems and their components

Certification or declaration of conformity

Certification shall be carried out with regard to equipment of categories 3 and 4 according to schemes 1c, 7c (for series-produced products), 3c (for batch of products) and 4c (for single item).
