1.1这些实践旨在概述参考阈上区域材料气味强度的首选方法。 1.2一般目标是参考样品的气味强度，而不是其他气味特性。 1.3这些实践旨在参考任何有气味材料的ASTM气味强度参考量表上的气味强度。这是通过将样品的气味强度与一系列参考气味剂浓度的气味强度进行比较来实现的，即1- 丁醇（-丁醇）。 1.4规定了提交参考气味蒸汽以供专家评估的方法。测试样本的呈现方式将取决于样本的性质，本文未对其进行定义。 1.5试样展示应符合良好标准惯例（1） 并应明确记录在测试报告中。 1.6本标准可能涉及危险材料、操作和设备。本标准并非旨在解决与其使用相关的所有安全问题。 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。

1.1 These practices are designed to outline a preferred means for referencing the odor intensities of a material in the suprathreshold region. 1.2 The general objective is to reference the odor intensity rather than other odor properties of a sample. 1.3 These practices are designed to reference the odor intensity on the ASTM Odor Intensity Referencing Scale of any odorous material. This is done by a comparison of the odor intensity of the sample to the odor intensities of a series of concentrations of the reference odorant, which is 1-butanol ( -butanol). 1.4 The method by which the reference odorant vapors are to be presented for evaluation by the panelists is specified. The manner by which the test sample is presented will depend on the nature of the sample, and is not defined herein. 1.5 Test sample presentation should be consistent with good standard practice (1) and should be explicitly documented in the test report. 1.6 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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.
