Fabric Systems: Evaporative Resistance

Downloads:

Methods:

ASTM F 1868 “Thermal and Evaporative Resistance of Clothing Materials Using a Sweating Hot Plate Test” (Procedure Part B)

ISO 11092 "Textiles--Determination of Physiological Properties--Measurement of Thermal and Water-Vapour Resistance" 

Instrument:

Sweating hot plate in an environmental chamber; custom hoods provide either horizontal or vertical air flow at different levels

Cost:

$375 per fabric type (3 reps)

 

ERF
Flooding the plate.  See photos of plate and hoods under Fabric Systems: Thermal Insulation.
ERF
Water is covered with a PTFE liquid barrier to keep the fabric sample dry during the evaporative resistance test.
