This report contains data and information about monolithic porous materials for acetylene cylinders.

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

In this European Technical Report 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

Pressure values given in this European Technical Report are given as gauge pressure (pressure

This Technical Report contains information about monolithic porous materials used in individual

acetylene cylinders and in acetylene cylinder bundles. It does not claim to be exhaustive.

NOTE Where there is any conflict between this European Technical Report and any applicable regulation, the

The following documents are referred to in the text in such a way that some or all of their content

constitutes requirements of this document. For dated references, only the edition cited applies. For

undated references, the latest edition of the referenced document (including any amendments) applies.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

The data contained in the tables in Clauses 6, 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

NOTE 1 The documentation provided was examined carefully before including the according information into

this 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 Report. In some cases not all

information was available in the documents provided and consequently the according information is missing (for

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

Where no official documentation could be made available to CEN/TC 23/WG 31, no information is

included in this technical report, meaning that the information is not exhaustive. This is of especial note

in the case of reassessed acetylene cylinders, since every user can ask for a specific reassessment.

Clause 6 contains information on porous materials for acetylene cylinders approved or reassessed to

TPED. It also contains information on filling conditions for acetylene cylinder bundles in accordance

Clause 7 contains information on porous materials used in individual acetylene cylinders that were type

Clause 8 contains information on porous materials used in acetylene cylinder bundles that were

If several years are indicated for the approval or certification they refer to according amendments in

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)

In this Technical Report 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

Sub-clause 6.1 contains information on porous materials for pi-marked acetylene cylinders which were

placed or still are on the market. Such porous materials are type tested in most cases according to

EN ISO 3807, EN 1800 or ISO 3807-1. It also contains information on filling conditions for acetylene

NOTE 1 according to ADR:2015 EN 1800 was used for type approvals until December 2016. ISO 3807-1 is used

for the type approval of UN-Cylinders and EN ISO 3807 is used for non-UN-Cylinders.

NOTE 2 EN 1800 and ISO 3807-1 were superseded by EN ISO 3807 in 2013. Nevertheless type approvals for

The following tables are ordered alphabetically according to the name of the porous material.

Column 1 gives the cylinder water capacities, in l, to which the filling conditions (solvent content,

acetylene content, working pressure) as given in the subsequent columns are applicable.

Column 2 lists the specified solvent content, in kg/l, that the acetylene cylinder shall contain per litre

water capacity in accordance with the type tests according to EN ISO 3807, EN 1800 or ISO 3807-1.

Column 3 lists the maximum acetylene content (including saturation acetylene), in kg/l, that the

acetylene cylinder shall contain per litre water capacity in accordance with the type tests according to

EN ISO 3807, EN 1800 or ISO 3807-1. Filling tolerances, especially depending on the scale, have to be

Column 4 lists the working pressure (always given as gauge pressure [bar]) of the acetylene cylinder as

calculated in accordance with EN ISO 3807, EN 1800 or ISO 3807-1. For bundles it gives the maximum

no. of consecutive fillings before the bundle has to be dismantled and solvent has to be replenished in
