Scope
This European Standard specifies the Sweating Torso as a method to
measure the coupled heat and mass transfer through protective clothing
in fire fighters’ specific conditions.

NOTE The Sweating Torso is developed to perform highly reproducible
laboratory tests for heat and mass transfer on clothing systems under
controlled conditions which are closely correlated to real conditions. The
Sweating Torso is a cylinder with the same size as a human trunk. The
layers of the measurement cylinder are made of compact Teflon,
polyethylene and aluminium. Due to this combination of materials,
transient processes can be modelled. Thus, changes in the skin and core
temperature can be simulated. The Sweating Torso contains a total of 54
independently-controlled sweating nozzles. In order to avoid any axial
heat loss, the cylinder has a heated guard at each end. The cylinder and
the thermal guards are heated electrically using heating foils. The
Sweating Torso can be run either with constant surface temperature or
with constant heating. The whole Sweating Torso is placed on a
precision scale to assess the evaporated and condensed amount of
water.
