Thermal Evaluation of Headwear

Property:
Resistance to dry heat transfer (insulation value) and/or the evaporative resistance provided by headwear and helmet systems

Method:
There is no standard method for evaluating headwear; the basic procedures in the whole body manikin standards ASTM F 1291 and ASTM F 2370 will be followed

Instrument:
Thermal sweating head in an environmental chamber

Specimen number and size: 1 or 3 sets of garments sized to fit the head

Cost for insulation tests:
$550 for 3 replications in a row on one hat or helmet; $650 for replications on 3 headwear samples of the same type

Cost for evaporative resistance tests:
$750 for 3 independent replications
