1.1 本试验方法涵盖一个小规模实验室程序，通过在受控半绝热系统中暴露于空气中的高温来确定油基材料的自加热趋势。 1.2 开发本试验方法是为了解决识别可能需要标记自发加热倾向的油基材料的迫切需要。基于该试验方法的研究可能有助于制定识别此类油基材料的实践。 1.3 以国际单位制表示的数值应视为标准值。括号中给出的值仅供参考。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 有关处理溶剂浸泡抹布的安全问题，请参阅 附录X1 . 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 本试验方法提供了一种加速材料自发加热的方法，这种自发加热可能最终导致火灾。 适用于液体和糊状物。 5.2 油基材料的自发加热行为受以下因素影响:氧气的可用性、存在的干燥器的数量、油的聚合度、纤维素材料的表面积、防止散热的措施以及与纤维素材料接触的油量。自发加热的程度与油基材料接触的纤维素材料类型或是否首先风干油浸材料关系不大。少量污染物，如油漆、石英粉尘、污垢或干燥器（例如，可能在脏的油料上发现的材料）- 浸泡过的rag）可以作为该反应的催化剂。 4.

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 standard. The values given in parentheses are for information only. 1.4 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. For safety concerns specific to disposal of solvent-soaked rags, see Appendix X1 . 1.5 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. ====== Significance And Use ====== 5.1 This test method provides a means of accelerating the tendency of a material toward spontaneous heating that may eventually lead to a fire. It is applicable to liquids and pastes. 5.2 The spontaneous heating behavior of an oil-based material is affected by such factors as the availability of oxygen, the amount of driers present, the degree of polymerization of oils, the surface area of the cellulose material, measures to prevent heat dissipation, and the amount of oil in contact with cellulose material. The degree of spontaneous heating bears little relationship to the type of cellulose material to which an oil-based material comes in contact or whether or not oil soaked materials are first air dried. Small amounts of contaminants, such as oil paint, quartz dust, dirt or drier (for example, materials that might be found on a dirty, oil-soaked rag), can act as catalysts for this reaction. 4
