Taking the Next Step in Harmonization: Key Changes in IEEE 515-2011
Bibliographic record
Abstract
Since its initial publication in 1983, IEEE 515 has been the primary industrial trace heating standard in the United States and the basis for many other international industrial trace heating standards. With the overall objective of one worldwide standard for industry, the goals of the revised IEEE P515 were to incorporate technical updates and further harmonize with international industrial trace heating standards. The two industrial trace heating standards considered were International Electrotechnical Commission (IEC) 60079-30-1 and -2 [1], [2] and Canadian Standards Association (CSA) 130-03 [3]. This article presents the key changes in IEEE 515-2011 [4], the process used for harmonization, and the rationale for the additions and changes.

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.
