Product Design Parameters and Conformance Testing

The examples in this section illustrate how to represent lists of design parameter specifications and testing for conformance to those specifications using three tobacco product categories: cigarettes (Example 1), ENDS devices (Example 2), and smokeless tobacco products (Example 3). Each example starts with a TO dataset, followed by a Product Design Parameters (PD) dataset and a Tobacco Product Testing (PT) dataset.

Note that tobacco product testing for conformance to design parameters would typically require multiple replicates for each parameter being tested. In SDTM, each replicate would be represented in its own record, differentiated by using the PTREPNUM variable (repetition number), which would be set to values of 1 through n (where n = the total number of replicates being tested). For simplicity of review, each example uses the PTREPNUM variable, but only for 1 record (1 repetition). In reality, if only 1 record for a given parameter or analyte is collected, the PTREPNUM variable would not be used.

Example

This example illustrates the representation of a cigarette product's identifiers and descriptors using the TO domain. Note that this example uses TOSCAT (Subcategory of Tobacco Prod ID Element, a permissible variable) to emphasize and differentiate the 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 intended for use are represented in the 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.

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 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.

The manufacturing parameter specifications of the portioned snus tobacco product as intended for use are represented in the PD domain. The following example shows the target, minimum, and maximum values associated with each of 10 separate design parameters. These parameters are defined manufacturing specifications, not characteristics that are determined experimentally.

Finally, the PT domain is used to represent the actual results of testing the manufactured portioned snus product for conformance to the tobacco product design parameters shown in PD. PTCAT is a Required variable and is set to "DESIGN PARAMETER TESTING" for all records here. 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.
