HOW THIS VERIFICATION WORKS

  1. Step 1: Estimate Cpk from binomial defect rate with confidence-interval-adjusted sigma — performs a deterministic calculation from the provided inputs. No acceptance criterion is applied; the result is CALCULATED only.
  2. Step 2: Assign IEC 62443-3-3 security impact weights to SHAP-importance-ranked features — performs a deterministic calculation from the provided inputs. No acceptance criterion is applied; the result is CALCULATED only.

This tool coordinates 0 validation steps and 2 calculation steps. The overall engineering decision uses ALL_REQUIRED_VALIDATION_PASS aggregation: only validation steps contribute to the pass/fail outcome; calculation steps produce data only.

METHODS & EQUATIONS

All formulas are resolved from canonical runtime definitions and executed deterministically by the client-side engine.

Step 1: Cpk from Binomial Defect Rate with Confidence-Interval-Adjusted Sigma

Calculationmin((usl_fnr - observed_fnr) / (3 * sqrt(observed_fnr * (1 - observed_fnr) / sample_size)), (observed_fnr - lsl_fnr) / (3 * sqrt(observed_fnr * (1 - observed_fnr) / sample_size)))

Step 2: Workflow Step

CalculationN/A

UNDERSTANDING THE RESULTS

PASS
A proven validation criterion passed. The engineering input satisfies the deterministic threshold.
FAIL
A proven validation criterion failed. The engineering input does not satisfy the deterministic threshold.
CALCULATED
A deterministic calculation completed, but no acceptance criterion exists for this step. CALCULATED does NOT mean PASS.
RESULT NOT VALID
Runtime executed but engineering validity requirements were not met.
INCOMPLETE
Required inputs or workflow steps are incomplete.

The overall decision reflects only validation steps. Calculation steps produce numerical results without pass/fail claims.

WHEN TO USE THIS TOOL

  • When deterministic Battery Grading System engineering verification is needed for project-specific conditions.
  • For calculation of Estimate Cpk from binomial defect rate with confidence-interval-adjusted sigma (Step 1).
  • For calculation of Assign IEC 62443-3-3 security impact weights to SHAP-importance-ranked features (Step 2).
  • For deterministic pre-checks before formal engineering review or submission.

When NOT to use this tool: This tool does not replace laboratory testing, formal engineering analysis by a licensed professional, or code-compliance certification. It performs deterministic threshold comparison and calculation only.
