- other pressure vessels containing:
- harmful fluids (toxic or corrosive)
- fluids with flash point below 100°C
- fluids with temperature above 220°C
- fluids with pressure above 40 bar
- compressed gases where
pd × V ≥1500 bar ltr
- boilers and hot water generators, including equipment, valves and fittings
- thermal-oil heaters, including equipment, valves and fittings
- oil or gas burners and oil or gas firing equipment.
pd = design pressure
V = volume.
Pressure equipment according to [1.1.2] are subject to certification by the Society.
