1. Legal Restrictions of Tar Oil Impregnation

Impregnation oils from coal tar (otherwise known as tar oils or creosotes) were the first

wood preservatives to gain industrial importance. Even today, their extensive protection

against biological attack is unsurpassed. Tar oils are especially suited for

are in permanent contact with the ground or water. The impregnated wood, after many

years in service, may be easily burned since creosote does not leave a (hazardous)

residue. In fact the heat value is even increased with the impregnation.

substances - especially benzo[a]pyrene

Therefore, legislative authorities have issued restrictions for the use of creosote.

3. European Classification of Impregnation Oils

In Europe, at present three types of preservatives exist according to the European

Standard EN 13991 with the labels Grade A, Grade B and Grade C, whereas use of

Grade A is forbidden since July 2003. The physical parameters of the EN 13991 grades

are based on the well known WEI standards. The technical data of the labels are

summarized in the following table. Compliance with the technical requirements does

not necessarily mean that the oil is suitable for all applications. This has to be proven

for each new use.

Classification of tar oils:

Grade A: forbidden according to 2001/90/EC

Grade B: wood poles and all other applications

Grade C: new generation of tar oils with reduced odor. They can replace

4. The different Impregnation oil Grades

Tar oils are products from the distillation of coal tar, consisting of a large number of

chemical compounds. The contribution of a single ingredient depends on the dividing

line of the tar distillation, therefore the boiling curve of tar oils is an importa

characteristic (see Figure 1).
