Comment |
Provides additional recorded information, if any, about the test.
|
Conductance (Thermal) |
The time rate of steady-state heat flow through a unit area of a material or construction
induced by a unit temperature difference between the specimen surfaces (in
W·m-2·K-1 or
Btu·h-1·ft-2·°F-1).
|
Conductivity (Thermal)
|
The time rate of
steady-state heat flow through a homogeneous material induced by a unit
temperature gradient normal to the unit area (in
W·m-1·K-1) or
(Btu·in·h-1·ft-2·°F-1).
|
Date |
Date of test (month, day year [xx/xx/xxxx]). |
Delta T |
Difference of hot and cold plate temperatures in K or °F.
|
Description |
Provides additional recorded information describing the test specimen.
|
Final Moisture Content
|
The amount of water (by mass) present in the test specimen at the end of the test in %.
|
Form |
Describes the physical
characteristics of the material. Can be one of the following: blanket,
block, board, loose, pipe, slab, spray, or woven.
|
ID |
The database internal identification number.
|
Initial Moisture Content
|
The amount of water (by mass) present in the test specimen at the start of the test in %.
|
Interposed Sheets? |
For purposes of modifying
the specimen-plate interface, have sheets of another material been
interposed between the test specimens and apparatus plates? [Yes or No].
This field provides information on variation of the test method.
|
Material |
Generic name of material of
test specimen. Some materials may have additional information that can be
seen in the detail page. If it is available, a button saying: "Click for
material info" appears.
|
Material Designation |
If available, specifies the
Trademark® or Trade Name of test specimen. Some trade names may have
additional information that can be seen in the detail page. If it is
available, a button saying: "Click for designation info" appears.
|
Material Source |
Name of manufacturer or third-party source of test specimen.
|
Mean Temperature |
Average of hot and cold
plate temperatures corresponding to the temperature at the mid-plane of
the test specimen in °C or °F.
|
Mode of Operation |
Specifies either the
traditional two-sided mode of operation for a pair of identical specimens,
or one-sided for a single specimen [2 or 1] . This field provides
information on variation of the test method.
|
Other Specimen |
Specifies the name of the
material of the other specimen if the test mode of operation is 1.
|
Pre-test
Conditions
|
Specifies the ambient
conditions (temperature, humidity, time), if available, that the specimen
was conditioned to prior to testing.
|
Resistance (Thermal) |
The quantity determined
by the temperature difference, at steady state, between two defined
surfaces of a material or construction that induces a unit heat flow rate
through a unit area (in m2·K·W-1 or
h·ft2·°F·Btu-1).
|
Resistivity (Thermal)
|
The quantity determined
by the temperature difference, at steady state, between two defined
parallel surfaces of a homogeneous material of unit thickness, that
induces a unit heat flow rate through a unit area (in m·K·W-1
or h·ft2·°F·Btu-1·in-1).
|
Select Units |
SI refers to the International System of Units, universally abbreviated SI (from the French Le Système International d’Unités). The term IP (also I-P) is an abbreviation for inch-pound and refers to the system of customary units commonly used in the United States.
|
Sheet Material |
Provides the material name
if sheets have been inserted between the test specimen and plates.
|
Specimen Number |
Assigns a unique
identification number to the test specimen.
|
Specimen Thermocouples
|
Indicates if thermocouples
have been installed directly on the faces of the specimens.
|
Thermal Property |
Heat transmission property
based upon steady-state, one-dimensional heat-transfer tests, including
thermal conductance, thermal resistance, (apparent) thermal conductivity,
and (apparent) thermal resistivity, among others. The thermal transmission
properties of heat insulators and other building materials determined from
standard test methods typically include several mechanisms of heat
transfer including conduction, radiation, and possibly convection.
|
Thickness |
Thickness of cross-section of
test specimen in mm or inches.
|
Uncertainty |
The relative expanded
uncertainty for the estimate for the thermal transmission property of
interest in %. Unless explicitly stated, the relative expanded
uncertainty for most estimates of the thermal transmission properties
ranges from 2 % to 3 % for heat insulators and 10 % for other
materials.
