Cigarette ventilation and circumference cross-checks are conducted between Development Center, Technical Center, and Macon Branch. Cross-checks are done to standardize Filtrona Ventilation Meters and Circumference Gauges situated at each facility. The cigarettes used in the cross-checks are produced in Development Center. Usually two production runs a year are enough to provide all the cigarettes required to do the checks. During production, both ventilation and circumference are tightly controlled. After manufacture, the cigarettes are randomized before and after packaging to insure that each participant uses cigarettes from the same population. The cigarettes are kept in Technical Center and are distributed to the participants. Development Center's Quality Assurance Laboratory will issue the cigarettes each day. TESTING PROCEDURE: 1. Each morning, the Filtrona Circumference Gauge and Ventilation Meter will be calibrated using designated standards for each. 2. After calibration each day, 25 of the cigarettes mentioned in Item 1 under Sample Preparation Procedure will be measured in the Filtrona Circumference Gauge. This same group of 25 will be measured in Filtrona Ventilation Meter. The cigarettes are discarded, and a new group is used the following day. 3. The data generated under Item 2 will be recorded on a Cross-Check Sheet. A copy of the Cross-Check Sheet is attached. 4. The Cross-Check Sheet is sent to Technical Center and the data is compared to that generated in Technical Center and Macon Branch. 5. The results are compiled on a data sheet by Technical Services, and a copy is sent to Development Center. A copy of the Data Sheet is attached. 0490M(5/20/89) Attachments TO: Mr. J. F. Nall Mr. R. H.
