Abstract
Abstract The Atlas cell test (NACE TM0174) and the autoclave test (NACE TM0185) are laboratory tests that are regularly used to select internal linings for vessels and tanks used in processing oil and gas production fluids. The results from the two tests are often quite different and in some notable instances the correlation between Atlas cell test results and field performance is poor. This paper documents our investigation of the various operational details of the Atlas cell test and their influence on the nature of the cold wall effect created in the Atlas cell. A number of commonly used tank linings were evaluated under Atlas cell conditions. The results are used to offer an explanation regarding some of the contradictory behaviour of coatings in Atlas testing, autoclave testing, and field performance.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
