ASTM D 1518 Document Information:
Title
Standard Test Method for Thermal Transmittance of Textile Materials
ASTM International
Publication Date:
Jul 26, 1985
Scope:
This test method covers the determination of the overall thermal
transmission coefficients due to
the combined action of conduction, convection, and radiation for dry
specimens of textile fabrics,
battings, and other materials within the limits specified in 1.2. It
measures the time rate of heat
transfer from a warm, dry, constant-temperature, horizontal flat-plate
up through a layer of the
test material to a relatively calm, cool atmosphere.
For practical purposes, this test method is limited to determinations
on specimens of fabrics,
layered fabric assemblies, and battings having thermal transmittances
(U2, as defined in 3.1.2)
within a range of 0.7 to 14 W/m²·K and thicknesses not in
excess of 50 mm.
The coefficients obtained apply strictly only to the particular
specimens tested and for the
specified thermal and environmental conditions of each test. This test
method gives values that are
valid for comparison under the same conditions of test, that is, with
the specified air velocity,
temperature difference between the warm plate and the cool air, and
air gap for measuring cool air
temperature.
The values stated in metric units are to be regarded as the standard.
Conversion factors, for
thermal conductance and conductivity and thermal resistance and
resistivity, to other units in
common use are given in Tables 1-5
This standard does not purport to address the safety concerns
associated with its use. It is the
responsibility of whoever uses this standard to consult and establish
appropriate safety and health
practices and determine the applicability of regulatory limitations
prior to use.
