Pressure equipment covers a very broad and diverse field, including domestic products (e.g. cookware such as whipped cream sprays and pressure cookers) to industrial equipment (e.g. pressure vessels and facility piping, safety fittings and unfired pressure equipment).

The placing on the market of pressure equipment is subject to four specific regulations depending on the type of device. They aim to cover the risks arising from the pressure to which the devices are exposed during use (e.g. explosion, parts coming loose).

Pressure equipment

Pressure equipment refers to: pressure vessels, facility piping, safety fittings and pressurised accessories. Pressure equipment can also refer to the elements that are attached to pressurised components, such as flanges, tubes, couplings, crane lugs, etc.

Examples include pressure cookers, steam appliances, etc.

Simple pressure vessels

A simple pressure vessel is a welded vessel with an internal overpressure of more than 0.5 bar. It is intended to contain air or nitrogen, but is not intended to be fired.

Example: the container for an air compressor.


Aerosols are single-use containers made of metal, glass or plastic that contain compressed, liquefied or dissolved gas under pressure, with or without a liquid, paste or powder. The containers are equipped with a release device, which allows the contents to be ejected in the form of solid or liquid particles in suspension in a gas, or in the form of foam, liquid, paste or powder, or in a liquid state.

Some examples include hair spray, whipped cream spray cans, paint spray cans, etc.

Transportable pressure equipment

Transportable pressure equipment come under the jurisdiction of the FPS Mobility and Transport.

Transportable pressure equipment can be described in general terms as receptacles or tanks that are used for transporting certain gases and dangerous substances.

Some examples include tanks, battery vehicles, closed cryogenic vessels, etc.
