This standard has been revised by ISO 3838:2004
The first method is also for use with solids and this method may also be used for coal tar products, including road tars, creosote and tar pitches or for mixture of these with petroleum products. This method is not suitable for highly volatile liquids. The second method is recommended for the accurate determination of all except the more viscous products.
