4.1 A standard procedure is necessary to establish an evaporation equation for spilled oils or petroleum products.

4.2 This procedure employs standardized equipment and test procedures.

1.1 This test method covers methods to measure the rate of evaporative weathering and then adjust the resulting equation to provide prediction of evaporation at various temperatures. The results of this test method can provide oil behavior data for input into oil spill models and response method selection.

1.2 This test method covers specific procedures for oil evaporation and does not cover all possible procedures that may be applicable to this topic.

1.3 The results obtained using this test method can be used directly to predict oil spill evaporation or as input to oil spill models.

1.4 The accuracy of the test method depends very much on the representative nature of the oil sample used. Certain oils can have different properties depending on their chemical contents at the moment a sample is taken.

1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
