此前由ASHRAE资助的研究开发了一种名为“Formula#9”的烟草气味模拟物。ASHRAE委员会TC 2.3决定制定气体过滤介质的试验方法。授予了一个项目，以确定配方#9是否可以在试验方法中用作质疑过滤器的气味介质。该项目的目的是使用标准测试管道和由50%木炭和50%Purafil制成的通用过滤介质，将真实烟草烟雾与配方9进行比较。™1972年，ASHRAE赞助了一个三阶段项目，即RP-111项目，题为“烟草烟雾中气味成分的测定”，目的是开发一种由可重复模拟烟草烟雾气味的特定化学物质组成的配方。 该项目的第一阶段包括各种烟草烟雾气味的气相色谱和感官测量。测定了烟草烟雾的主要气味成分，以及不同数量的几种烟草烟雾源（香烟、雪茄和烟斗烟）的气味强度。这项工作产生了一份出版物。*第一阶段测定的气味相关成分在第二阶段通过质谱法进行鉴定。在第三阶段，一种被称为ASHRAE Formula#9的合成烟草烟雾气味模拟混合物被配制出来。文献中也报告了第二阶段和第三阶段的结果。**第三阶段的一个关键方面是感官评估，并将配方#9（以及其他配方）与真实烟草烟雾气味进行比较。 气味专家组的九名成员都报告说，公式#9确实模拟了烟草烟雾的气味，在可能的100分中，他们总共给了84分。据信，可以在上述工作的基础上开发使用该配方的试验方法。该配方可用于相对简单的试验装置，使过滤器制造商能够测量其过滤介质的有效性。这将有助于制造商生产有效的过滤器，并有助于客户评估各种产品。*A.德拉夫尼克斯、J.惠特菲尔德和J.沙阿。烟草烟雾中气味成分的测定。ASHRAE Trans。，80，第一部分，76- 91**A.德拉夫涅克、A.奥唐纳和H.R.赖利希。烟草烟雾中气味成分的测定:模拟气味的混合物设计。ASHRAE Trans。，81，第一部分，200-212

Previous work funded by ASHRAE resulted in the development of a tobacco odor simulant known as Formula #9. ASHRAE Committee TC 2.3 decided to develop a test method for gaseous filtering media. A program was awarded to determine if Formula #9 could be used in the test method as the odorous medium to challenge the filters. The objective of the program was to compare real tobacco smoke to Formula #9 using a standard test duct and generic filter media made of 50 percent charcoal and 50 percent Purafil.™In 1972 ASHRAE sponsored a three-phase program, Project RP-111 entitled "Determination of Odor Components in Tobacco Smoke", in order to develop a formulation consisting of defined chemical substances that could reproducibly simulate tobacco smoke odor. Phase I of the program consisted of gas chromatographic and sensory measurements of a variety of tobacco smoke odors. It was determined the major odor components of tobacco smoke and the odor intensity of different quantities of several tobacco smoke sources (cigarettes, cigars, and pipe tobacco). A publication resulted from this work.* The odor-relevant components determined in Phase I were identified by mass spectrometry in Phase II. In Phase III, a synthetic tobacco smoke odor simulant mixture known as ASHRAE Formula #9 was formulated. The results of Phases II and III were also reported in the literature.** One critical aspect of Phase III was the sensory evaluation and comparison of Formula #9 (and the other formulations) against real tobacco smoke odor. All nine members of an odor panel reported that Formula #9 did simulate tobacco smoke odor and collectively gave it a score of 84 out of a possible 100.It was believed that a test method using this formulation could be developed based on the above work. The formulation could be used in a relatively simple test setup which would allow filter manufacturers to measure the effectiveness of their filtering media. This would aid the manufacturer in the production of effective filters and the customer in evaluating various products.* A. Dravnieks, J. Whitfield, and J. Shah.
