1.1 本指南总结了通过蒸发风化分馏油的方法，然后测量风化油的特性和行为。本指南的结果可以为输入溢油模型和响应方法选择提供石油行为数据。 1.2 本指南涵盖了石油风化和行为的一般程序，但未涵盖可能适用于本主题的所有可能程序。 1.3 使用本指南获得的结果旨在提供溢油时石油和石油产品行为的基线数据，并输入溢油模型。 1.4 使用本指南获得的结果可直接用于预测漏油行为的某些方面，或作为漏油模型的输入。 1.5 导轨的精度在很大程度上取决于所用油样的代表性。根据取样时的化学成分，某些油可能具有不同的性质 1.6 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.7 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。 1.8 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 有必要制定标准程序，以确定溢油或石油产品在不同石油风化阶段的性能变化。 5.2 该程序采用标准化设备和测试程序。 5.3 该程序应在与相关泄漏条件相对应的风化阶段执行。

1.1 This guide summarizes methods to fractionate oil by evaporative weathering and then measure the properties and behavior of the weathered oil. The results of this guide can provide oil behavior data for input into oil spill models and response method selection. 1.2 This guide covers general procedures for oil weathering and behavior and does not cover all possible procedures which may be applicable to this topic. 1.3 The results obtained using this guide are intended to provide baseline data for the behavior of oil and petroleum products when spilled and input to oil spill models. 1.4 The results obtained using this guide can be used directly to predict certain facets of oil spill behavior or as input to oil spill models. 1.5 The accuracy of the guide depends very much on the representative nature of the oil sample used. Certain oils can have different properties depending on their chemical contents at the moment a sample is taken 1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.7 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. 1.8 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 A standard procedure is necessary to establish property changes for spilled oils or petroleum products at different oil weathering stages. 5.2 This procedure employs standardized equipment, and test procedures. 5.3 This procedure should be performed at the stages of weathering corresponding to the spill conditions of interest.
