South Korea Ministry of Employment and Labor apparent-temperature heat rule and 2025 implementation notices.

No standalone formula is published for this standard; see programmable logic and parameters below.
Governing metric: Apparent temperature
Programmable logic: Uses the binding 2025 MoEL rule that requires at least 20 minutes of rest within every 2 hours of heat work at apparent temperature 33°C and above. The calculator keeps separate advisory fields for the 35°C and 38°C outdoor-work notices instead of treating them as hard statutory stop-work thresholds.
This standard does not take WBGT as a required input, and publishes no standalone numeric parameter table here; see the governing metric and programmable logic above, and the primary source below.
Required inputs: none
Optional inputs: date, outdoor, heatIndexC, heatIndexF, airTempC, relativeHumidity
