    Abstract - (Show below) - (Hide below)

    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.

    Scope - (Show below) - (Hide below)

    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.
