Annex A
(normative)
Thermal properties of sleeping bags
Foreword
Different methods are applied throughout Europe for characterisation of thermal properties of sleeping bags. They rely on
measurement of thermal insulation of the sleeping bag with a thermal manikin and calculation of the lower limits of the range
of utility on the basis of a predictive physiological model. Additively one method also includes water vapour permeability of
the sleeping bag to upper limit of the range of utility.
An interlaboratory test, involving three different laboratories, was organised within present CEN working group on a set of 8
sleeping bags filled with feathers and downs. Two human shaped thermal manikins were used (one with 15 independent seg-
ments, the other with 35 segments), corresponding to CEN requirement for testing protective clothing against cold; one further
manikin was a single segment mummy shaped manikin which provides a figure related to its external heat loss.
The test showed the following conclusions:
even with multi-sectional manikins, the design and especially the number of independent sections may
influence the value of thermal insulation by more than 10 %;
yet all manikins, including the simple one, correlate within a range of ± 10 % (95 % confidence interval) through a linear
relation intrinsic to each manikin;
A.1 Scope
This annex describes the method for the assessment of the performance in steady state conditions of a sleeping bag with regard
to the protection against cold provided. It applies to sleeping bags for an adult person.
A.2 Principle
The measuring device is a thermal manikin which is positioned into a sleeping bag placed in a controlled cold
ambiance. Thermal loss is measured when stationary conditions are reached and, applying the result of a calibration procedure,
a standard thermal insulation of the bag is deduced. A physiological model is then applied, which uses the standard thermal
insulation to calculate ambient temperatures corresponding to a range of utility of the sleeping bag.
A.3 Terms and definitions
A.3.1
thermal manikin
inert mass internally heated:
with shape and dimensions such that, when placed in the bag, occupation of internal volume of the sleeping bag is repre-
sentative of a human body;
offering the possibility to determine thermal transfer through the sleeping bag under steady state conditions (i.e. constant
heat flux and temperature gradient).
A.3.2
standard thermal insulation
property of the sleeping bag which is related to the dry heat loss of the sleeping bag user (combination of conduc-tive, convec-
tive and radiative heat transfer), to the difference of temperature between skin and ambient air, as measured with a thermal
manikin.
