1.1 This guide covers standard procedures for the quantitative sensory assessment of perceived olfactory intensity of indoor malodors for the purpose of assessing the deodorant efficacy of air care products. This guide is limited to static conditions only.
1.2 It is recognized that, sometimes desirable, the use of actual "live" malodors is often impractical due to the inherent variability of the malodor sources. A true malodor source may be used when practical. However, the use of a formulated odor source has several advantages, including consistency and availability.
1.3 The reader should be aware of good sensory practices when preparing the test environment or substrate, developing and training the panel.
1.4 The researcher is responsible for identifying the most appropriate test design and using the appropriate statistical tool to address the experimental design.
1.5 This guide is a compendium of information or series of options that does not recommend a specific course of action. This guide is not intended to support claims. If the research objective is claim related, then the researcher needs to refer to Guide E 1958.
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. Specific precautionary statements are given in Section 6 and X18.104.22.168.
