The drag-to-check calculator needs JavaScript. Every value it can show is a row of the table below, which is computed by the same engine.
No standalone formula is published for this standard; see programmable logic and parameters below.
| Parameter | Value |
|---|---|
equivalentTempCeilingC | 33 |
wetBulbWeight | 0.9 |
dryBulbWeight | 0.1 |
recordFromC | 30 |
Programmable logic
te = 0.9*wetBulbC + 0.1*airTempC. te > 33: ceiling exceeded; work above it needs special authorisation from the mining authority (urgent cases allowed with precautions and constant technical control). te > 30: temperatures must be recorded daily and intake/return air measured (reported as a control). Screening limit only: no work/rest schedule or stop-work trigger. Applies to underground mining (industry mining).
Required inputs: wetBulbC, airTempC
Optional inputs: none
