Meaning and use

5.1 This test method provides a tendency to accelerate the spontaneous combustion of the material, which can eventually lead to a fire. Suitable for liquids and pastes.

5.2 The spontaneous heating behavior of oil-based materials is affected by the availability of oxygen, the amount of desiccant present, the degree of polymerization of the oil, the surface area of the cellulosic material, the measures taken to prevent heat dissipation, and the amount of oil in contact with the cellulosic material. The degree of spontaneous heating is independent of the type of cellulosic material in contact with the oil-based material or whether the oil-immersed material is first air-dried. Small amounts of contaminants, such as paint, quartz powder, dirt, or desiccant (for example, materials that may be found on dirty, oil-soaked rags), can act as catalysts for this reaction.

Step 1: Scope

1.1 The test method includes a small-scale laboratory procedure to determine the self-heating tendency of oil-based materials exposed to high temperatures in air in a controlled semi-adiabatic system.

1.2 This test method was developed to address the urgent need to identify oil-based materials that may need to be labeled with a tendency to self-heating. Research based on this test method could allow the development of practices to identify such oil-based materials.

1.3 Values expressed in SI units shall be regarded as standard values. The values given in parentheses are for reference only.

1.4 This standard is not intended to address all safety concerns, if any, associated with its use. It is the responsibility of users of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.
