HOW THIS VERIFICATION WORKS

  1. Step 1: Identify reseal pressure as last pressure value before sustained sub-threshold flow during depressurization — compares engineering inputs against deterministic thresholds and produces a PASS or FAIL decision.

This tool coordinates 1 validation step and 0 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: Identify reseal pressure as last pressure value before sustained sub-threshold flow during depressurization

Manual Workflow
Traverse Q_d(t) backward from end of series; locate last time index where Q_d(t) ≥ Q_th. Then find first subsequent index where Q_d(t) < Q_th AND remains below Q_th for ≥ t_off/Δt consecutive samples. Assign P_rs = P_d(t) at the *first* sample of that compliant interval. Compute ΔP_hys = abs(P_cr − P_rs). Reject if P_rs > 0.9 × P_cr (indicating incomplete reseal).

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 Vent Valve engineering verification is needed for project-specific conditions.
  • For validation of Identify reseal pressure as last pressure value before sustained sub-threshold flow during depressurization (Step 1).
  • 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.
