17、, based on the results of specied ammability tests, for the classication of uids or liquids as nonammable, or as ammable with the degree of re hazard rated both in general terms and on a numerical scale, in comparison with well-known products whose hazards have been established by eld experience. 1.
18、2 The classications derived by this method are evaluations of the inherent ammability of liquids and their vapors. Increases in re hazard due to partial evaporation of components of certain liquid mixtures during handling and use are taken into account in assigning the re hazard classication. The as
19、signed classications do not apply when the liquid is dispersed in the atmosphere in the form of nely divided spray, mist, or fog. 1.3 The liquids may be pure chemical compounds, homogeneous mixtures or solutions, emulsions, or multilayer combinations of immiscible liquids. The liquid products may co
20、ntain undissolved solid materials, either in suspension or as a separate layer. 1.4 This method of classication with respect to re hazard is applicable to liquids which are essentially stable materials. Liquids susceptible to dangerous decomposition reactions during phase change or when exposed to h
21、eat or mechanical shock, and liquids subject to hazardous exothermic polymerization, are considered unstable materials within the intent of this Standard. It should be ascertained that the product is stable with respect to these features before applying the tests specied in this Standard. Evaluation
22、 of the more severe hazards presented by such unstable materials requires considerations which are beyond the scope of this Standard. 1.5 The classications derived by this method are with respect to re hazard only. The assigned ratings do not cover other potential hazards, including the physiologica
23、l effects of the products, in any form, nor do they indicate the efficiency or effectiveness of the products in their intended uses. 2 General 2.1 Units of measurement 2.1.1 Values stated without parentheses are the requirement.
