1.1 This test method covers a small-scale laboratory procedure to determine the self heating tendency of oil-based materials by exposure to elevated temperatures in air in a controlled semi-adiabatic system.

1.2 This test method has been developed to address an urgent need to identify oil-based materials that may require labeling for spontaneous heating tendency. Studies based on this test method may allow the development of a practice to identify such oil-based materials.

1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

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 and health practices and determine the applicability of regulatory limitations prior to use. For safety concerns specific to disposal of solvent-soaked rags, see Appendix X1.
