HOW THIS VERIFICATION WORKS

  1. Step 1: Solve constrained threshold optimization via inverse normal CDF intersection — engineering workflow step. Follow the documented method for manual execution.
  2. Step 2: Compute sample size for Cpk hypothesis test using noncentral chi-squared approximation — engineering workflow step. Follow the documented method for manual execution.

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: Solve constrained threshold optimization via inverse normal CDF intersection

Manual Workflow
τ_opt = (σ_0 * σ_1 * (norm_inv(1 − α_max) + norm_inv(1 − β_max)) + μ_0 * σ_1² + μ_1 * σ_0²) / (σ_0² + σ_1²); α_act = 1 − Φ((τ_opt − μ_0)/σ_0); β_act = Φ((τ_opt − μ_1)/σ_1), where Φ is standard normal CDF and norm_inv is its inverse — per IEC 62660-1 Annex D decision-theoretic validation framework.

Step 2: Compute sample size for Cpk hypothesis test using noncentral chi-squared approximation

Manual Workflow
n_min = ⌈2 × [(z_{1−α} + z_{1−β}) / (√2 × (Cpk_target − 1.0))]² + 3⌉ — derived from asymptotic variance of Ĉpk estimator and noncentral chi-squared inversion per ISO 22514-2:2017 Annex B; conservative integer ceiling ensures ≥90% power for Cpk ≥1.33 claim.

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 Leak Tester engineering verification is needed for project-specific conditions.
  • For calculation of Solve constrained threshold optimization via inverse normal CDF intersection (Step 1).
  • For calculation of Compute sample size for Cpk hypothesis test using noncentral chi-squared approximation (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.
