1 Scope
This Technical Report gives guidance on the use of conformity assessment procedures for unfired pressure
vessels as covered by Article 1, § 2.1.1 of the Pressure Equipment Directive (PED). The PED requires all pressure
equipment falling within its scope to have its design and manufacture assessed for conformity in accordance with a
series of conformity assessment procedures given in Article 10 of the PED. These procedures are described in
detail in Annex III of the PED to which reference must be made in order to ensure compliance. The following
summary is given for guidance purposes only.
2 Normative references
This Technical Report incorporates, by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply to this Technical
Report only when incorporated in it by amendment or revision. For undated references the latest edition of the

European
Union this organisation should be a notified body or a recognised third-party organisation or a user
inspectorate, as appropriate according to module chosen, and designated by a Member State. For the purpose of
this standard all these organisations have been collectively termed “responsible authorities”

4 Application of the PED
4.1 General
The PED requires that for each pressure vessel the hazard category should be determined. Thereafter the
manufacturer should choose the module or combination of modules of conformity assessment from those permitted
recognizing that:

each individual vessel should be manufactured to a single module or a combination of modules;

each series of identical vessels (including batches) should be manufactured to a single module or a
combination of modules.
4.2 Classification of pressure vessels in hazard categories
For the purpose of classification of pressure vessels in hazard categories, fluids (gas or liquid) are divided into two
groups:
Group 1: This group comprises dangerous fluids (under Council Directive 67/548/EEC (27 June 1967),
Article 2 (2)), i.e. fluids defined as:

explosive;

extremely flammable;

highly flammable;

flammable (where the maximum allowable temperature is above flashpoint);

very toxic;

toxic;

oxidizing.
Group 2: This group comprises all other fluids not referred to in Group 1.
In combination with the internal volume (V) and/or the maximum allowable pressure (PS) of the vessel this leads to
four specific cases:
a) Fluids in Group 1; Vessels for gases, liquefied gases, gases dissolved under pressure, vapours and also
liquids whose vapour pressure at the maximum allowable temperature is greater than 0,5 bar above normal
atmospheric pressure (1 013 mbar), within the following limits: V > 1 L and PS


 
 
b) Fluids in Group 2; Vessels for gases, liquefied gases, gases dissolved under pressure, vapours and also
liquids whose vapour pressure at the maximum allowable temperature is greater than 0,5 bar above normal
atmospheric pressure (1 013 mbar), within the following limits: V > 1 L and PS · V > 50 bar·L, or,
PS > 1000 bar;
c) Fluids in Group 1; Vessels for liquids having a vapour pressure at the maximum allowable temperature of not
more than 0,5 bar above normal atmospheric pressure (1 013 mbar), within the following limits: V > 1 L and
PS ·V > 200 bar·L, or, PS > 500 bar;
d) Fluids in Group 2; Vessels for liquids having a vapour pressure at the maximum allowable temperature of not
more than 0,5 bar above normal atmospheric pressure (1 013 mbar), within the following limits: PS > 10 bar
and PS · V > 10 000 bar·L, or, PS > 1 000 bar.

CR 13445-7:2002 (E)
Issue 1 (2002-05)
Pressure vessels are classified in hazard categories I to IV according to one of the relevant cases a) to d) and their
volume and maximum allowable pressure. The classification has been defined in the Figures A.1 to A.4.
4.3 Conformity assessment procedures
4.3.1 General
The manufacturer should subject each vessel to a procedure to assess the conformity with the essential
requirements of the PED. A list of conformity assessment procedures is given in Table B.1.
4.3.2 Choice of conformity assessment procedure
The conformity assessment procedures to be applied to a vessel with a view to affixing the CE marking should be
determined by the hazard category in which the vessel is classified. The procedures that are to be applied for the
various hazard categories are given in Table B.2.
The vessel manufacturer has the option of selecting between a procedure of conformity assessment involving a
quality assurance system (if available) and one which does not.
The manufacturer may also choose to apply one of the procedures which apply to a higher category, if available.
4.3.3 Conformity assessment procedures and the involvement of Responsible Authorities
The manufacturer is responsible for ensuring that the requirements of EN 13445, including inspection and testing
activities, are fully applied. If a CE marking is sought, it is a requirement of the PED that (in many cases) there is a
supplementary involvement of a Responsible Authority (e.g. Notified Body) to ensure the requirements of the PED
are met. The involvement of User Inspectorates is restricted to the modules A1, C1, F and G.
Serially produced pressure vessels manufactured to Annex A of EN 13445-5 refer to "Model Acceptance". For
vessels manufactured to satisfy the PED, the requirements for model acceptance can be considered as "Type
Approval" (Module B) providing the responsible authority has been involved at the appropriate time. Several
conformity modules are based on the design element of a type approval.
The kind and extent of responsible authority involvement in inspection and testing activities will depend upon the
conformity assessment procedure chosen by the manufacturer. For each appropriate conformity assessment
procedure the participation is indicated in Table C.
Annex C has been provided in order to give guidance to the different parties so that they may be aware of the
various stages where a responsible authority may be involved. Details of the inspection and testing activities are
described in subsequent sub-clauses, the reference of which is given in Table C.
5 Subcontracting
Where the manufacturer is producing the pressure vessel under a conformity assessment procedure requiring
intervention of a responsible authority, the manufacturer should inform the responsible authority of his intention to
subcontract so that the responsible authority has the opportunity to take part in the subcontractor surveillance.
NOTE Where the manufacturer is producing the equipment under a conformity assessment procedure based on quality
assurance, e.g. D, H, H1, the controls the manufacturer applies over subcontractors should be described in his appropriate
quality system.
