โœฆ Synopsis

A simple, inexpensive test measuring the volatility or fuming propensity of bituminous materials with good repeatability has been devised. The test depends on measuring the mass loss which occurs when a small sample of the material is heated in a shallow open dish on a thermostatic hotplate for a fixed time. A rectilinear inverse relation between the mass losses and the softening points of a series of pitches from one source has been found, and the test has been shown to give results which correlate well with other methods for characterizing pitch volatility. Test results obtained with a range of tar products from pitches to creosotes all showed similarly good repeatability.

A test, replacing the distillation test for pitches, has been developed. In this test, a sample is placed into an aluminium dish which is introduced into the cavity of a metal block preheated to a selected temperature. The surface of the sample is in a constant stream of nitrogen preheated to the te
