Abstract
Due to the revision of the Montreal Protocol (Copenhagen- November 1992), CFCs will be phased out at the end of 1995. The European Union (EU) has adopted a more severe position and will ban CFCs by the end of 1994. In order to face this challenge, Elf Atochem has developed a comprehensive range of CFC alternatives. Today, CFC-12 can easil be replaced by the FORANEQ 134a or the FORANEQ FX56 (retrofit) and R-502 by the FORANE 8 FX70 or the FORANEB FXlO (retrofit). During the last two years, Elf Atochem's new FORANE @ refrigerants have been intensively tested in the field, first, by compressor manufacturers, second, by equipment manufacturers and contractors. FORANEB blends are today recognized by major compressor manufacturers and are requested by major supermarket chains for retrofits. Large number of retrofits have been performed on various systems through a wide range of technology all over the world. This paper puts forwards a selection of representative experiences where Elf Atochem brought technical assistance and follow-up, in order to assess FORANE @ products performance. Upon these experiences, it appears that data and observations reported by contractors indicate that

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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
