European foreword
This document (EN 13991:2024) has been prepared by Technical Committee CEN/TC 317 “Derivatives
from coal pyrolysis”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by January 2025, and conflicting national standards shall
be withdrawn at the latest by January 2025.
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 EN 13991:2003.
— a revision is required due to legal changes to the marketing of Creosote in Europe. According to
Regulation 1907/2006/EC (Annex XVII, Entry 31, Restrictions), only Creosote Grades with a
benzo[a]pyrene content below 50 mg/kg are allowed to be placed on the EU market. This means
that former Creosote Grade A with a benzo[a]pyrene content up to 500 mg/kg is no longer allowed
and has therefore been deleted from the standard;
— additional restrictions by Commission Implementing Regulation (EU) 2022/1950 related to use
and storage have been taken into account;
— test methods originating from BS 144 have been integrated as informative Annex D due to
withdrawal of BS 144;
— normative references and bibliography have been updated.
Annexes A and B are normative. Annexes C and D are informative.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and the
United Kingdom.

4 Sampling
Samples for the assessment of the parameters listed in Table 1 shall be taken in accordance with
EN 1014-1.
5 Specifications and test methods
Specifications for Creosote Grade B and C and the relevant test methods are given in Table 1.
Creosote is intended to protect wooden railway sleepers, utility poles (overhead power and
telecommunication lines) and wood for other uses permitted in the receiving country.
Creosote in use should not contain more than 3 % of water.

NOTE According to Regulation 1907/2006/EC (Annex XVII, Entry 31, Restrictions) only creosote with a
benzo[a]pyrene content lower than 50 mg/kg may be marketed in Europe. This means that former grade A
quality with a benzo[a]pyrene content of max. 500 mg/kg is no longer allowed to stay on the market. Grade A
was therefore deleted.
a
The density is determined at a temperature above the crystallization temperature. For each degree Celsius
above 20 °C, a fixed value of 0,7 kg/m is added to the density reading.
b
As an alternative, the distillation method of ISO 3733 can be used.
Annex A
