Comparative inclined plane tests on silicone and EPDM elastomers under DC
Bibliographic record
Abstract
The paper presents comparative inclined plane test results of high temperature vulcanized silicone rubber and EPDM elastomers filled with alumina trihydrate to 25 wt% under DC. Both the initial tracking voltage and the constant voltage test methods are employed to evaluate the relative tracking/erosion resistance of both elastomers. While insignificant differences between the tracking/erosion resistance of the two elastomers is observed, earlier failure occurs under -DC. A recognizable distinction is also found between the failure pattern and the corresponding dry-band arcing current. Shorter non-conduction periods in the leakage current are observed on the silicone rubber elastomer prior to failure, a result that indicates stable discharge activity, which is more evident under +DC than under -DC. Imbedded in the stable dry band arcing current are transient leakage current pulses due to probable ionization activity, which can be seen to enhance the intensity of the discharge. In contrast, intermittent dry band arcing current is found to be dominant for the EPDM elastomer.

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.
