Path to EU Market Entry for Pressure Equipment: Compliance

Assessment and conformity procedure are different for each category, in which the equipment is classified (Art.14):



Essential Safety Requirements

The Annex I of the Directive defines certain safety requirements about the design and performance of pressure equipment, such as:


- equipment must be designed for adequate strength taking into account internal/external pres-sure, ambient and operational temperatures, static pressure and mass of contents in operating and test conditions, traffic, wind, earthquake loading, corrosion and erosion, fatigue, decomposi-tion of unstable fluids;

- it must be ensured safe handling and operation of examination;

- adequate means shall be provided for the draining and venting of equipment;

- equipment must be provided with protection against exceeding the allowable limits of pressure;

- where necessary, pressure equipment must be designed and fitted with suitable accessories to meet damage-limitation requirements in the event of external fire.


Specific requirements are defined for materials used for the manufacturer of pressure equipment.


Harmonized Standard

Pressure equipment or assemblies, which are in conformity with harmonized standards or parts thereof,  which have been published in the Official Journal of the European Union, shall be presumed to be in conformity with the essential safety requirements covered by those standards or parts thereof, referred to in Annex I.

The materials used for the manufacture of pressure equipment or assemblies which are in conformity with European approvals for materials, the references of which have been published in the Official Journal of the European Union, shall be presumed to be in conformity with the applicable essential safety requirements set out in Annex I.

There is a special category of pressure equipment and assemblies - below or equal to the limits set out in all the other categories - which must be designed and manufactured in accordance with the Sound Engineering Practice (SEP) of a Member State to ensure safe use.

The Essential Safety Requirements of the Directive do not apply to product falls in the SEP category but can be a good guidance in absence of other instructions. A derogation it is also made for the CE marking of SEP, since Article 4 paragraph 3 explicitly prohibits CE marking of SEP pressure equipment.


Technical Documentation

The manufacturer shall draw up the technical documentation referred to in Annex III of the Directive.
