意义及用途

5.1 该测试方法提供了加速材料自燃的趋势, 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, 比如油漆, quartz powder, dirt, or desiccant (例如, materials that may be found on dirty, oil-soaked rags), can act as catalysts for this reaction.

ASTM D6801-2015 测量艺术品和其他材料的最大自热温度的标准测试方法

步 1: 范围

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 以 SI 单位表示的值应视为标准值. 括号内的数值仅供参考.

1.4 本标准并非旨在解决所有安全问题, 如果有的话, 与其使用相关. 本标准的使用者有责任建立适当的安全和健康实践，并在使用前确定监管限制的适用性. Refer to Appendix X1 for specific safety issues related to the treatment of solvent-impregnated rags.
