Cigarette ignition propensity testing: three brands of Kreteks
Bibliographic record
Abstract
The ignition propensity of three brands of Kreteks (the Djarum Super, the Djarum Special, and the Djarum Black) was determined through a series of tests in accordance with the ASTM E2187-04 "Standard Test Method for Measuring the Ignition Strength of Cigarettes". The relative ignition strength was determined by observing the percentage of the cigarettes that burned their full length. In addition, the length of the remaining tobacco column was measured for all those cigarettes that self-extinguished during the test.Test results showed that the Djarum Super and the Djarum Black had relatively high numbers of full-length burns. The Djarum Super Kretek cigarettes burned their full length 75%, 95% and 100% of the time, and the Djarum Black Kretek cigarettes burned their full length 92.5%, 92.5% and 100% of the time, on the 15-layer, 10-layer and 3-layer assemblies, respectively.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
