1.1这些试验方法包括观察特征和残余气味以及估计甲醇、乙醇、， n -丙醇和异丙醇，以确定其气味可接受性。包括几种试验方法，可以使用任何或全部方法。这些试验方法可用于变性和未变性酒精。 1.2这些试验方法的目的不是确定醇类之间的细微气味差异，这不会影响其最终用途。 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和健康实践，并确定监管限制的适用性。 ====意义和用途====== 这些试验方法旨在提供可用于评估含1至3个碳原子的变性和未变性醇的特征气味和残余气味的程序，这些气味和残余气味将影响其最终用途。 使用所述的一种或所有测试方法将测试的产品与参考标准进行比较。特定最终用途的结果解释和产品可接受性是专家组主管的责任，并基于测试中获得的结果。 这些测试可用于鉴定这些产品在客户中的适用性- 生产者关系。

1.1 These test methods cover procedures for observing characteristic and residual odors and estimating odor intensity of methanol, ethanol, n -propanol, and isopropanol for the purpose of determining their odor acceptability. Several test methods are included and any or all may be used. These test methods may be used for both denatured and undenatured alcohols. 1.2 These test methods are not intended to determine subtle odor differences between alcohols, which do not affect their end use. 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== These test methods are intended to provide procedures that may be used to evaluate denatured and undenatured alcohols with 1 to 3 carbon atoms for characteristic and residual odors that will affect their end use. The products tested are compared to reference standards using one or all of the test methods described. Interpretation of results and acceptability of the product for a specific end use are the responsibility of the panel supervisor and are based on the results obtained in testing. These tests may be used to qualify the suitability of these products for use in a customer-producer relationship.
