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

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.
