European foreword
This document (CEN/TR 14473:2020) has been prepared by Technical Committee CEN/TC 23
“Transportable gas cylinders”, the secretariat of which is held by BSI.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes CEN/TR 14473:2014.
Compared to the previous version, the following changes apply:
a) data of further porous materials has been added;
b) the structure of the document has been changed:
— Clause 7 contains data for porous materials for acetylene cylinders approved to TPED
evaluation of conformity at time of manufacture;
— Clause 8 contains data for porous materials for acetylene cylinders reassessed in accordance
with TPED;
— Clause 9 contains data for porous materials for individual acetylene cylinders and that are type
approved based on national regulations;
c) the document has been aligned with the current principles and rules for the structure and drafting
of CEN and CENELEC documents.
For amendments or changes to this report, an application shall be made to the Secretariat of
CEN/TC 23, with a copy of the documentation based on which the acetylene cylinders are placed on the
market (type approval by the competent authority or conformity assessment in accordance with
Directive 2010/35/EU (TPED)).
Introduction
This document contains data and information about monolithic porous materials for acetylene
cylinders.
It does not contain information about non-monolithic porous materials.
In International Standards, weight is equivalent to a force, expressed in newton. However, in common
parlance the word “weight” continues to be used to mean “mass”, but this practice is deprecated
(ISO 80000-4).
In this document the unit bar is used, due to its universal use in the field of technical gases. It should,
however, be noted that bar is not an SI unit, and that the according SI unit for pressure is Pa
5 5 2
(1 bar = 10 Pa = 10 N/m ).
Pressure values given in this document are given as gauge pressure (pressure exceeding atmospheric
pressure) unless noted otherwise.
1 Scope
This document contains information about monolithic porous materials used in individual acetylene
cylinders and in acetylene cylinder bundles in Europe. It does not claim to be exhaustive.
NOTE Where there is any conflict between this document and any applicable regulation, the regulation
always takes precedence.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
No terms and definitions are listed in this document.

4 Source and nature of the data about the listed porous materials
The data contained in the tables in Clauses 7 and 8 are derived from the documentation based on which
the acetylene cylinders were placed or still are on the market (type approval by the competent
authority or conformity assessment in accordance with TPED) and according to which they are
operated. In some cases a type approval or a TPED-certificate might no longer be valid but the cylinders
that are already on the market still may be used. For this purpose, information on old porous materials
is provided.
NOTE 1 The documentation provided was examined carefully before including the according information into
this Technical Report. Nevertheless, there might be discrepancies to the actual approval, e.g. because more recent
amendments exist which were not made available at the time of preparing this document. In some cases not all
information was available in the documents provided and consequently the according information is missing (for
example the maximum top clearance or the working pressure).
Acetylene cylinders that were reassessed in accordance with TPED may be filled with the filling values
conforming to the reassessment certificate throughout the EU. It should be noted that these values
might deviate from those of prior national approvals which still apply to those cylinders that were not
reassessed according to TPED.
Where no official documentation could be made available to CEN/TC 23/WG 31, the data for the porous
material is added with a note, that this information is shared by expert/porous material manufacturer
as extracted from the official documentation, but has not been presented to the working group. This is
of especial note in the case of reassessed acetylene cylinders, since every user can ask for a specific
reassessment.
Clause 7 contains information on porous materials for acetylene cylinders approved to TPED. It also
contains information on filling conditions for acetylene cylinder bundles in accordance with
EN ISO 13088:2012. The same filling ratio applies for the whole EU.
Clause 9 contains information on porous materials used in individual acetylene cylinders and cylinder
bundles that were type approved based on national regulations and/or standards.
If several years are indicated for the approval or certification, they refer to according amendments in
addition.
NOTE 2 The initial agreements of the French porous materials have been delivered on the basis of a data pair
“porous material/cylinder manufacturer”. Therefore, the name of the cylinder manufacturer has been detailed:
Chevalier Bertrand (CB), Schneider Industrie (SI), Pecquet Tesson (PTC), Société Métallurgique de Gerzat (SMG)
and Siebel (S).
NOTE 3 Every user (owner) of a cylinder can decide on its own commercial acetylene load, provided that this
load is less or equal to the maximum load given in the agreement.
5 Country codes
In this document, countries are identified in accordance with their distinguishing signs for motor
vehicles according to the Vienna Convention on Road Traffic, which is also the basis for marking of
cylinders according to the ADR (see Annex A to the ADR, 6.2.2.7) as follows:
A Austria  FIN Finland  NL Netherlands
B Belgium  GB United Kingdom  P Portugal
BG Bulgaria  GR Greece  PL Poland
CH Switzerland  H Hungary  RO Romania
CZ Czech Republic  HR Croatia  S Sweden
D Germany  I Italy  SK Slovakia
DK Denmark  IRL Ireland  SLO Slovenia
E Spain  L Luxembourg
F France  N Norway
