Another dimension of odor is its character, or what the odor smells like. ASTM publication DS 61 (Dravnieks 1985) presents character profiles for 180 chemicals using a 146 descriptor scale. The scale uses terms such as fishy, nutty, moldy, rancid, sewer, and ammonia.

Table 5.26.1 provides a short list of the industrial odor character descriptions.
