OECD 103 Testing of Chemicals - Standard Test Method for Boiling Point

EUROLAB, together with its state-of-the-art accredited laboratories and expert team, provides precise and rapid testing services within the scope of OECD 103 testing. This test guide describes methods for determining the boiling point of test substances. The boiling point of a liquid is defined as the temperature (in K) at which its vapor pressure equals the standard atmospheric pressure of 101.325 kPa.

The effect of impurities on the boiling point is largely dependent on the nature of the impurity. The methods described in this Test Guide are applicable to liquids and low melting substances, provided they do not undergo chemical change below their boiling point.

The methods are: ebulliometry, dynamic method, distillation method, method according to Siwoloboff, photocell detection, differential thermal analysis, differential scanning calorimetry.

Photocell detection and thermal analysis allow determination of boiling and melting temperatures. The advantage of the dynamic method is that it can also be applied to the determination of vapor pressure.

The OECD guidelines for testing chemicals are a collection of approximately 150 of the most relevant internationally recognized test methods used by government, industry and independent laboratories to identify and characterize the potential hazards of chemicals. They are a set of tools for professionals used primarily in regulatory safety testing and then in chemical and chemical product declaration, chemical registration and chemical evaluation.
