Designation: C1616 −07 (Reapproved 2018)
Standard Test Method for
Determining the Moisture Content of Organic and Inorganic
Insulation Materials by Weight
1
This standard is issued under the ﬁxed designation C1616; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This test method will determine the moisture content, as
a percentage of the dry weight of organic and inorganic
insulation materials.
1.2 The values stated in inch-pound units are to be regarded
as the standard. The values given in parentheses are for
information only.
1.3 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.
1.4 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.

C302 Test Method for Density and Dimensions of Pre-
formed Pipe-Covering-Type Thermal Insulation

formed Block and Board–Type Thermal Insulation

3. Terminology
3.1 Deﬁnitions—For deﬁnitions used in this speciﬁcation,
see Terminology C168.
3.2 Symbols:
3.2.1 M—moisture content weight, percent.
3.2.2 W
I
—initial specimen weight, lb (g).
3.2.3 W
MF
—moisture-free specimen weight (g) M, lb.
4. Summary of Test Method
4.1 This test method is based upon weighing specimens of
the insulation material and then drying the specimens by
heating them in an oven to remove any moisture. Then the
moisture content is determined using the calculation procedure
in 9.1.
5. Signiﬁcance and Use
5.1 Some insulation materials contain moisture, which will
affect the thermal and other physical properties of the insula-
tion.
6. Apparatus
6.1 Air-circulating Oven.
6.2 Scale (accurate to within 0.0011 lb (0.5 g).
7. Sampling and Test Specimen Preparation
7.1 Test Specimen—The test specimen shall be of a size that
can be conveniently tested in a drying oven but not less than 72
cubic inches in volume such as 6 by 6 by 2 in. thick (150 by
150 by 51 mm).
8. Procedure
8.1 Four test specimens shall be tested. Cut or prepare the
four specimens to meet the size requirements of 7.1.
8.2 Measure and record the specimens weight (W
I
) imme-
diately after the specimens are prepared to size. The specimens
shall be weighed to the nearest 0.0011 lb (0.5 g).
8.3 Place the specimens in an air-circulating oven at a
temperature speciﬁed in the material speciﬁcation or at a
temperature no higher than 230 610°F (110 66°C) for a
minimum of 2 h. Cool the specimens to room temperature in a
desiccator and measure their weight. Repeat the process until
successive weights agree to within 0.2 % of the specimen
weight obtained in the latest weighing. Record these weights as
moisture free weight (W
MF
).

Insulation and is the direct responsibility of Subcommittee C16.33 on Insulation
Finishes and Moisture.

NOTE 1—When testing an insulation that contains multiple ingredients

and one or more ingredients will dehydrate between the material speciﬁ-

cation upper temperature limit or above, the oven temperature can be

lowered. The oven temperature will be adjusted based on the chemical the

dehydrates at the lowest temperature.

9. Calculation

9.1 Calculate the moisture content as follows:

M5100

(1)

9.2 The value reported shall be the numerical average of the

calculated moisture content of the four specimens rounded to

the nearest 0.1 percent.

10. Report

10.1 Report the following information:

10.1.1 Complete sample identiﬁcation including trade

name, manufacturer, lot number and date of production, when

known,

10.1.2 Date and time of test initiation,

10.1.3 Date and time of all weight determinations along

with the weights,

10.1.4 Actual temperature used to dry the sample,

10.1.5 Time to reach steady dry weight, and

10.1.6 Report the results of all the specimens tested for each

sample and the numerical average calculated in 9.2.

11. Precision and Bias

11.1 Precision and bias have not yet been determined but are

being investigated. A precision and bias statement will be

included when the proper data have been obtained and ana-

lyzed.

12. Keywords

12.1 inorganic insulation; insulation; moisture content; or-

ganic insulation; water; weight
