1 Scope
This Technical Report gives guidance on the use of conformity assessment procedures for industrial piping and
pipelines as covered by Article 1, § 2.1.1 of the Pressure Equipment Directive (PED). The PED requires all pres-
sure 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 nor-
mative 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 publication re-
ferred to applies (including amendments).

3 Terms and definitions
For the purposes of this Technical Report, the following terms and definitions apply.
3.1
responsible authority
competent organisation which is independent of the manufacturer. For application within the jurisdiction of the
European Union this organisation may be a Notified Body, a recognised third-party organisation or a user inspec-
torate where 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"
3.2
fluid
gases, liquids and vapours in pure phase as well as mixtures thereof. A fluid my contain a suspension of solids
4 Application of the PED
4.1 General
According to the PED the manufacturer shall determine for each industrial piping and pipeline
a) the hazard category of the industrial piping and pipeline;
b) the procedures to be applied to assess conformity of the industrial piping and pipeline with the requirements of
the PED.
4.2 Classification of pressure equipment in hazard categories
For the purpose of classification of pressure equipment in hazard categories, fluids (gas or liquid) are divided into
two groups:
1) Group 1 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.
2) Group 2 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
4 specific cases:
a) Fluids in Group 1; Industrial piping 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 nor-
mal atmospheric pressure (1 013 mbar), within the following limits: DN > 25;
b) Fluids in Group 2; Industrial piping, 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 atmos-
pheric pressure (1 013 mbar), within the following limits: DN > 32 and PS x DN > 1 000 bar;
c) Fluids in Group 1; Industrial piping 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: DN > 25
and PS x DN > 2 000 bar;
d) Fluids in Group 2; Industrial piping 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 DN > 200 and PS x DN > 5 000 bar.
Industrial piping are classified in hazard categories I to III according to one of the relevant cases a) to d) and their
nominal diameter 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 shall subject each item of equipment to a procedure to assess the conformity with the essential
requirements of the PED. Annex B describes the conformity assessment requirements of the PED. It is applicable to
piping systems which are to be installed in an EU Member State.
4.3.2 Choice of conformity assessment procedures
The conformity assessment procedures to be applied to an item or pressure equipment with a view to affixing the
CE marking shall be determined by the hazard category in which the equipment is classified. The procedure that
are to be applied for the various hazard categories are given in table B.2-1.
The piping manufacturer has the option of selecting between a procedure of conformity assessment involving a
certified 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 this Technical Report, 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 require-
ments of the PED are met.
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 pro-
cedure the participation is indicated in Table C.1.
Annex C has been provided in order to give guidance to the manufacturer so that he 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.1.
5 Subcontracting
Where the manufacturer is producing the equipment under a conformity assessment procedure requiring interven-
tion of a responsible authority, the manufacturer shall 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 shall be described in his appropriate quality
system.

Annex B
Conformity of industrial piping to the essential safety requirements of Direc-
tive 97/23/EC (Pressure equipment directive)
B.1 Introduction
This annex describes the conformity assessment requirements of Directive 97/23/EC. It is applicable to piping sys-
tems which are to be installed in an EU Member State.
In the EU Member States, the authorized inspection bodies are identical to the notified bodies ).
B.2 Conformity assessment procedure
Where piping is subject to the conformity assessment procedure, the manufacturer shall identify the appropriate pip-
ing category based upon the classification of the piping as defined in table 4.1-1 of prEN 13480-1 and subsequently
shall select one of the conformity assessment modules available for that piping category in accordance with table B.2-
1.
NOTE The conformity assessment procedure attributed to a higher category may be applied to piping classified in a lower
category.
The activities to be performed by the parties involved in each of the conformity assessment procedures during de-
sign and fabrication/installation of the piping in accordance with this European Standard are summarised in An-
nex C.
