The following This example illustrates the representation of smokeless tobacco a cigarette product's identifiers and descriptors using the TO domain. Note that this example makes use of TOCAT (Category uses TOSCAT (Subcategory of Tobacco Product Prod ID Element, a permissible variable) to emphasize and differentiate the two 2 distinct types of parameters represented in TO: tobacco product identifiers and tobacco product descriptors. 

The manufacturing parameter specifications of the cigarette tobacco product as used intended for use are represented in the Product Design Parameters ( PD ) domain  The following example below shows the target, minimum, and maximum values associated with each of 19 23 separate design parameters. These parameters are defined manufacturing specifications, not characteristics that are determined experimentally.

Note the use of the variable IGDCMPID (Ingredient or Component Identifier) in rows 5-6. This tobacco product had 2 tobacco ingredients with 2 different tobacco cut sizes. IGDCMPID identifies to which tobacco ingredient the cut size applies. IGDCMPID originates in the IT (Tobacco Ingredients) and IN (Non-Tobacco Ingredients) domains. See Section 3.1.3.1, Ingredients and Additives, for more information.

Finally, the Tobacco Product Testing ( PT ) domain is used to represent the actual results of testing the manufactured cigarette product for conformance to the tobacco product design parameters shown in PD above. . PTCAT is a Required variable and is set to "DESIGN PARAMETER TESTING" for all records here. As described in the PD example, IGDCMPID is also used here to differentiate 2 records of the same test performed on each of 2 different types of tobacco that are ingredients of the tobacco product. Typically, applicants would submit data on each parameter in multiple replicates. For simplicity of review, only 1 replicate per parameter is shown. Note that PTREPNUM (repetition number) = 1 for all rows.
