Requirements for four types of coal tar creosote for wood preservation. Some test methods are included together with guidance on the methods of treatment of timber.

This British Standard specifies requirements for four types of coal tar creosote for wood preservation. Type 1 creosote is intended for treatment of timber by pressure impregnation.

Type 2 creosote is also intended for pressure impregnation, but has a more closely defined distillation range and a more restricted residue content than creosote of type 1. Type 2 creosote is especially suitable for treatment of poles for overhead power and telecommunication lines, and for structural timbers where bleeding in service could present a problem.

Type 3 creosote is intended for treatment of timber by immersion and brushing.

Type 4 creosote is intended for treatment of timber by pressure impregnation at temperatures > 100 °C. This creosote excludes the lower boiling fractions allowable in the other three creosote types and is especially suitable where volatility leading to odour is a problem.

NOTE. Creosote of types 1, 2 and 3 may be used for the hot-and-cold open tank process.
