In contrast to grade A, the distillation residue is loweredin order to reduce the benzo[a]pyrene content. It is especially suitable for treatment of poles for overheadpower 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 lowvolatility a reduction in odour is achieved.NOTE 2All types of creosotes are suitable for the hot-and-cold open-tank process.NOTE 3Creosote in use should not contain more than 3 % of water.NOTE 4The density is determined at a temperature above the crystallization temperature. For eachdegree Celsius above 20 °C, a fixed value of 0.7 kg/m3 is added to the density reading.SIST EN 13991:2003
