Heat Bluing Temperature Table Reader

Read a target temperature from a caller-supplied heat-bluing color table while preserving material, time, heating-rate, surface, and lighting limitations.

Description

A heat-bluing color table describes caller-supplied temperature bands.

A heat-bluing color table describes caller-supplied temperature bands. Color interpretation also depends on alloy, preparation, exposure and lighting.^[1]

Read a target temperature from a caller-supplied heat-bluing color table while preserving material, time, heating-rate, surface, and lighting limitations.

When to use Heat Bluing Temperature Table Reader

Use this tool to read a target temperature from a caller-supplied heat-bluing color table while preserving material, time, heating-rate, surface, and lighting limitations.

Choose a supported reference focus or prepare the watch measurements, evidence and explicit limits requested. Confirm units and date conventions before running.

How to use Heat Bluing Temperature Table Reader and understand its results

Choose a supported reference focus or prepare the watch measurements, evidence and explicit limits requested. Confirm units and date conventions before running.
Enter bandNames, targetTemperatureCelsius, temperatureBands using the field table and calculation rules, then run the tool.
Read matchedBandCelsius, matchedBandIndex, matchedBandName, tableCaveat. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
bandNames	Band names correspond by index to temperatureBands rows.	list of string	Required
targetTemperatureCelsius	Target metal temperature (degC)	number	Required
temperatureBands	Rows contain [minimum Celsius, maximum Celsius] and must be ordered.	list of list of number	Required

Enter nonempty ordered, nonoverlapping two-value bands and aligned names with finite target temperature. Touching boundaries are allowed; gaps are allowed but an unmatched target is an error. Return zero-based index, name, bounds and caution.

match first band containing target; [minimum,maximum), final band includes maximum

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
matchedBandCelsius	Matched temperature band (degC)	list of number
matchedBandIndex	Matched band index	integer; minimum: 0
matchedBandName	Matched color-band name	string
tableCaveat	Heat-bluing table caveat	string

Limitations and assumptions

No universal steel color chart or heating process is supplied.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Matrices are limited to 128 rows and 128 entries per row; other lists are limited to 100,000 entries. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
