Standard Test Method for Measuring Maximum Spontaneous Heating Temperature of Art and Other Materials

Importancia y uso:

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
