This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 317.

If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

European foreword
This document (prEN 13991:2022) has been prepared by Technical Committee CEN/TC 317 “Derivatives
from coal from pyrolysis”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 13991:2003.
A revision is required due to legal changes to the marketing of Creosote oils in Europe. According to Regulation
1907/2006/EC (Annex XVII, Entry 31, Restrictions), only Creosote oils with a benzo[a]pyrene content below
50 mg/kg may be placed on the market in Europe. This means that grade A quality with a benzo[a]pyrene
content below 500 mg/kg is no longer allowed to stay on the market and is therefore deleted from the
standard.
Annexes A and B are normative. Annex C is informative.

5 Specifications and test methods
Specifications for creosote grade B and C and the relevant test methods are given in Table 1.
Grade B is intended for pressure impregnation. In contrast to grade A, the distillation residue is lowered in
order to reduce the benzo[a]pyrene content. It is especially suitable for treatment of poles for overhead power
and telecommunication lines, and for structural timbers where bleeding in service can occur.
Grade C excludes the lower boiling fraction allowable in the other types of creosote and because of the low
volatility a reduction in odour is achieved.
Grade B and grade C are suitable for the hot-and-cold open-tank process.
Creosote in use should not contain more than 3 % of water.
