ASTA (Ausschuss für Sicherheit und Gesundheit bei der Arbeit an Arbeitsstätten) recommendation 'Hitzeschutz an Arbeitsstätten im Freien' for outdoor and not-fully-enclosed workplaces. Applies to outdoor and not-fully-enclosed workplaces only; computes a corrected Beurteilungstemperatur rather than reading raw indoor room temperature — see germany_asr_a35 for the indoor Raumtemperatur rule this recommendation does not replace or duplicate.

Outdoor and not-fully-enclosed workplaces only (ASTA §1); indoor rooms are governed by ASR A3.5, not this recommendation. With no relative humidity supplied the Tab. 4 Schwüle correction is reported as not evaluated rather than assumed zero, and with no wind speed supplied the Tab. 5 wind credit is not applied.
