Evaluation of cold environments — Determination of required clothing insulation (IREQ)

Proposes methods and strategies to assess the thermal stress associated with exposure to cold environments. Cold stress is suggested to be evaluated in terms of both general cooling of the body and local cooling of particular parts of the body (e.g. extremities and face). The methods apply to continuous, intermittent and occasional exposure and in both indoor and outdoor work. Specific effects associated with certain meteorological phenomena (e.g. precipitation) are not covered and should be assessed by other methods.
