HOW THIS VERIFICATION WORKS

  1. Step 1: Calculate voltage calibration error percent — performs a deterministic calculation from the provided inputs. No acceptance criterion is applied; the result is CALCULATED only.
  2. Step 2: Calculate current calibration error percent — performs a deterministic calculation from the provided inputs. No acceptance criterion is applied; the result is CALCULATED only.
  3. Step 3: Validate calibration status per NACE SP0198 tolerance — compares engineering inputs against deterministic thresholds and produces a PASS or FAIL decision.
  4. Step 4: Select minimum Rz per ISO 2063 Annex B ratio rule — performs a deterministic calculation from the provided inputs. No acceptance criterion is applied; the result is CALCULATED only.
  5. Step 5: Apply NACE RP0178 porosity limit for Zn/Al in chemical service — engineering workflow step. Follow the documented method for manual execution.
  6. Step 6: Compute deposition efficiency ratio using inverse-square model — performs a deterministic calculation from the provided inputs. No acceptance criterion is applied; the result is CALCULATED only.
  7. Step 7: Calculate efficiency loss percent — engineering workflow step. Follow the documented method for manual execution.
  8. Step 8: Verify efficiency loss does not exceed 10% threshold — compares engineering inputs against deterministic thresholds and produces a PASS or FAIL decision.
  9. Step 9: Compute atomizing air pressure using TWI empirical model — performs a deterministic calculation from the provided inputs. No acceptance criterion is applied; the result is CALCULATED only.

This tool coordinates 2 validation steps and 7 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: Calculate voltage calibration error percent

Formulaabs((V_meas-V_nom)/V_nom)*100

Step 2: Calculate current calibration error percent

Formulaabs((I_meas-I_nom)/I_nom)*100

Step 3: Validate calibration status per NACE SP0198 tolerance

Validation Rule
voltage_calibration_error_percent <= 2 [engineering_standard:NACE_SP0198_Section_7.3.2 AND current_calibration_error_percent]; current_calibration_error_percent <= 2 [engineering_standard:NACE_SP0198_Section_7.3.2 AND current_calibration_error_percent]

Step 4: Select minimum Rz per ISO 2063 Annex B ratio rule

FormulaPer ISO 2063:2012 Annex B, minimum Rz = 0.25 × t_coat for Zn/Al coatings on steel in corrosive service; round up to nearest 5 µm.

Step 5: Apply NACE RP0178 porosity limit for Zn/Al in chemical service

Manual Workflow
Per NACE RP0178 Section 5.4.2: maximum allowable porosity = 1.5 % for Zn/Al arc-sprayed coatings applied to carbon steel in chemical processing environments where continuous immersion or splash zone exposure is expected.

Step 6: Compute deposition efficiency ratio using inverse-square model

Formulapow((d_i/d_f),2)

Step 7: Calculate efficiency loss percent

Manual Workflow
Δη = (1 − η_ratio) × 100

Step 8: Verify efficiency loss does not exceed 10% threshold

Validation Rule
efficiency_loss_percent <= 10 [engineering_standard:ISO_2063_Annex_C]

Step 9: Compute atomizing air pressure using TWI empirical model

Formula0.023*W_target + 0.0015*d - 0.12*D_wire + 1.85

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.
