1. Scope
1.1 This guide provides recommended formats for the
recording of thermal transmission test data for thermal insula-
tion and similar materials for inclusion in computerized mate-
rial property databases. From this information, the database
designer is able to construct the database dictionary prepara-
tory for development of a database schema.
1.2 This guide is applicable to thermal transmission test data
obtained from standard test methods that cover planar and
radial specimen geometries.
1.3 This guide is not intended for thermal transmission data
obtained for thermal insulation assemblies or systems (that is,
heat transmission coefficients for walls, roofs, ceilings, and
ﬂoors).
1.4 This standard does not purport to address all of the
safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appro-
priate safety, health, and environmental practices and deter-
mine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accor-
dance with internationally recognized principles on standard-
ization established in the Decision on Principles for the
Development of International Standards, Guides and Recom-
mendations issued by the World Trade Organization Technical
Barriers to Trade (TBT) Committee.

3. Terminology
3.1 Deﬁnitions—For deﬁnitions of some terms applicable to
this guide, see Terminology C168
3.2 Deﬁnitions of Terms Speciﬁc to This Standard:
3.2.1 class, n—a major material class, for example, ceramic,
insulation, polymer, etc.
3.2.2 data element, n—an individual piece of information
used to describe a material or to record test results; for
example, a variable name or a test parameter.
3.2.2.1 Discussion—The term is synonymous with data
item.
3.2.3 essential ﬁeld, n—a ﬁeld in a record that shall be
completed in order to make the record meaningful in accor-
dance with the pertinent guidelines or standard.
3.2.3.1 Discussion—Fields are considered essential if re-
quired to make a comparison of property data from different
sources meaningful. A comparison of data from different
sources where essential information is omitted reduces the
value of the comparison.
3.2.4 ﬁeld, n—an elementary unit of a record that contains a
data item, a data aggregate, a pointer, or a link.
3.2.5 ﬁeld name, n—a name or code associated with a ﬁeld
and used for identiﬁcation.
3.2.6 form, n—the material form, for example, blanket,
board, or roll.
3.2.7 value set, n—an open listing of representative accept-
able text which is included in a particular ﬁeld of a record.
4. Signiﬁcance and Use
4.1 This guide deﬁnes the principal elements of
information, which are considered important and worth record-
ing and storing permanently in computerized databases. Suffi-
cient information is provided in this guide to enable the user to
construct a database structure suitable for the intended appli-
cation involving thermal insulation. Guidance on the storage of
(optional) digital images associated with test data is provided
in Appendix X1.

4.2 Because of increased activity in building computerized

materials databases and to maintain uniformity and ease of data

comparison and interchange, these formats provide for the

inclusion of speciﬁc elements of thermal transmission test data

in databases.

4.3 The key beneﬁt of using this guide is the establishment

of a systematic approach to the management of thermal

transmission test data. Other advantages include: (1) an in-

crease in data accuracy because new test data are vetted in real

time; (2) increased efficiency in data retrieval and storage; and,

(3) improved data consistency. Over time, historical data can

show important trends in the test measurements.

4.4 This guide has no implication on data required for

materials production or purchase. Reporting of actual test

results shall be as described in the actual materials speciﬁcation

or as agreed upon between the vendor and purchaser.

4.5 The suggested set of units for the recommended stan-

dard format given in this guide is SI. This guide, however, does

not preclude other sets of units, such as inch-pound (IP).

5. Recording of Test Data

5.1 Table 1 is a recommended standard format for the

computerization of thermal transmission data for thermal

insulation materials. The headings for each ﬁeld are:

5.1.1 Field Number—A reference number assigned to an

individual data ﬁeld that has no permanent value and does not

become part of the database.

5.1.2 Field Name and Description—The complete name of

the ﬁeld, descriptive of the data element of information of

interest.

5.1.3 Data Type—Type of data to be included in the ﬁeld,

such as the type of number, character text, logical values

(yes/no), and date.

5.1.4 Value Sets or Units—A listing of the types of infor-

mation which are included in the ﬁeld or, in the case of

properties or the numeric ﬁelds, the SI units in which the

numbers are expressed.

5.2 The presentation of the recommended standard format

does not require that every element of information be included

in every database. There is, however, a minimum number of

ﬁelds considered essential to any database and these ﬁelds are

marked with an asterisk (*).

NOTE 1—Many databases are prepared for speciﬁc applications and,

therefore, some database builders will omit certain elements considered to

be of no value for that speciﬁc application. Conversely, in some individual

cases, additional data elements are needed and the database builder is

encouraged to include these elements along with the elements in the

recommended standard format. It is important to note that not all of the

elements considered essential will be available for every test. Further, not

all of the ﬁelds included in the recommended standard format are

appropriate for all tests.

5.3 The recommended standard format is divided into ﬁve

sections as illustrated in Fig. 1: material identiﬁcation; micro-

structure; test method; specimen description; and test results

and analysis.

5.4 Fields that indicate the accuracy of each measurement

are beyond the scope of this guide. However, the entries in all

ﬁelds shall be given to the appropriate number of signiﬁcant

ﬁgures.

6. Material Identiﬁcation

6.1 The ﬁelds in this section identify the material tested.

NOTE 2—The numbers given in parentheses after the ﬁeld name refer to

the ﬁeld number in Table 1 and accompanying tables. Essential ﬁelds are

identiﬁed by an asterisk (*).

6.1.1 Material Reference Number (1*) —Unique database

identiﬁer containing material and process information for the

specimens. A typical value set contains information from the

material lot code (see Field 9).

6.1.2 Material Class (2*)—A major material class, for

example ceramic, insulation, metal, polymer, rubber, etc.

6.1.3 Material Name (3*)—A (generic) name for the par-

ticular material. A value set of typical responses is given in

Table 2.

6.1.4 Material Description (4*)—Descriptive name of ma-

terial tested, for example, E-type ﬁbrous glass with phenolic

binder.

6.1.5 Material Speciﬁcation (5)—Speciﬁcation and year of

issue for material name in ﬁeld (3). A value set of typical

responses is given in Table 2.

6.1.6 Material Designation (6)—Trade name, trademark,

brand name, etc., of material.

6.1.7 Material Manufacturer (7)—Manufacturer of material.

6.1.8 Material Source (8)—Source of material, if different

from manufacturer.

6.1.9 Material Lot Code (9)—Manufacturer identiﬁcation

(date, plant, etc.).

6.1.10 Date of Manufacture (10)—Date of manufacture.

6.1.11 Material Form (11)—Functional form of material. A

value set of typical responses is given in Table 2.

6.1.12 Material Classiﬁcation (12) —ASTM Classiﬁcation

for material, see particular material speciﬁcation (include year

of issue).

7. Microstructure

7.1 The ﬁelds in this section pertain to the microstructure of

the material and provide information complementary to the test

results and analysis given in 10. The information requested is

basic to the characterization of the insulation and is not

intended, in this condensed form, for prediction of thermal

performance.

7.1.1 Microstructure Type (13*)—Composition (cellular,

ﬁbrous, particle, etc.).

7.1.2 Cell Size (14)—Diameter of cells, if applicable.

7.1.3 Fiber Size (15)—Diameter of ﬁbers, if applicable.

7.1.4 Particle Size (16)—Diameter of particles, if appli-

cable.

7.1.5 Blowing Agent (17)—Name of blowing agent, if ap-

plicable.

7.1.6 Closed-cell Content (18)—Percentage of closed cells,

if applicable.

7.1.7 Binder Content (19)—Binder content, if applicable.

7.1.8 Shot Content (20)—Shot content, if applicable.
