Paint Pot Life Calculator
Completed mixed-coating workability trace crossings and right-censored below-threshold evidence, no chemical mixing/dosing, predictive Arrhenius potlife or readiness. Caller independently establishes units, regime, calibration and applicability; this does not establish design-code compliance, authenticity, operational safety, treatment efficacy or a validated forecast.
Description
Paint workability can be tracked through viscosity measurements after mixing.
Paint workability can be tracked through viscosity measurements after mixing.1
Observed threshold crossings differ from an assumed universal pot-life duration. Use Paint Pot Life Calculator to evaluate the supplied inputs under the model explained below.
When to use Paint Pot Life Calculator
Use Paint Pot Life Calculator to evaluate the supplied inputs under the model explained below. Establish the units, measurement scope and model assumptions before entering values.
How to use Paint Pot Life Calculator and understand its results
- Establish the units, measurement scope and model assumptions before entering values.
- Enter Observed paint elapsed minutes, Observed paint viscosity pa second, Caller verified maximum workability viscosity pa second using the field table and validation rules below, then run the tool.
- Read Observed workability threshold crossings minutes, Right censored below threshold; interpret the units, signs, ordering and unknown-value placeholders described below.
- Correct reported input errors and rerun. Apply successful results according to their specific meanings and check the assumptions before using them in a decision.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedPaintElapsedMinutes | Observed paint elapsed minutes | array of number | Required; constraints below |
| observedPaintViscosityPaSecond | Observed paint viscosity pa second | array of number | Required; constraints below |
| callerVerifiedMaximumWorkabilityViscosityPaSecond | Caller verified maximum workability viscosity pa second | number | Required; constraints below |
Enter at least two strictly increasing nonnegative elapsed minutes with aligned positive viscosities in Pa·s and a positive workability threshold in Pa·s. Return exact threshold sample times and linearly interpolated crossings in either direction. Consecutive duplicate crossing coordinates are suppressed, but a threshold plateau returns its sampled points. rightCensoredBelowThreshold is true only if there are no crossings and the final viscosity is below threshold. It does not extrapolate a later crossing or assess earlier unsampled history.
crossingTime = linear interpolation where viscosity crosses threshold; rightCensored = no crossings and finalViscosity<threshold Use the field order, units and branch conditions described above.
| Output field | Meaning | Value type |
|---|---|---|
| observedWorkabilityThresholdCrossingsMinutes | Observed workability threshold crossings minutes | array of number |
| rightCensoredBelowThreshold | Right censored below threshold | boolean |

}Limitations and assumptions
Observed threshold crossings differ from an assumed universal pot-life duration. Apply the exact scope and assumptions explained above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse arrays fail validation. Domain-specific bounds, alignments and supported tokens are explained above; extremely large inputs or outputs can also be rejected. Input errors differ from successful false results, empty match lists and unknown-evidence placeholders.
