Abstract
The effect of mass loading is an important phenomenon for the calibration of back-to-back accelerometers. When a transfer standard back-to-back accelerometer that has been calibrated for a given mass load is used to calibrate an accelerometer whose mass is different, an error is introduced. For this reason, accelerometer manufactures may supply correction curves for the mass loading effect or specify a maximum sensitivity change due to mass loads. These data, however, often have limited applicability. In this paper, the effect of mass loading on the shock sensitivity of some transfer standard accelerometers is presented. The shock-shaped excitation varied in amplitude from 5000 m/s2 to 10000 m/s2, for different mass loads from 37 g to 200 g. It has been found that the shock sensitivity of the accelerometers investigated decreases linearly as the load mass increases at a rate of about 0.007 %/g. This rate of decrease in shock sensitivity is almost constant for different shock accelerations.

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.
