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

3.2.2 high-temperature ﬁber thermal insulation—a thermal
insulation, varying in ﬂexibility, composed of refractory inor-
ganic ﬁbers, without binder added, and furnished in either ﬂat
sheets or rolls.
4. Classiﬁcation
4.1 The general-type product governed by this speciﬁcation
is blanket or batt composed of inorganic refractory ﬁbers.
4.2 Types—The product is separated into types based upon
temperatures of use (Table 1).
4.3 Grades—The product is separated into grades based
upon its maximum Apparent Thermal Conductivity values (see
Table 2) and minimum Tensile Strength values (see Table 3).
5. Ordering Information
5.1 High-temperature ﬁber blanket thermal insulation is
normally purchased on the basis of brand name, type, grade,
length, width, thickness, and total square footage as speciﬁed
in the purchase order.
5.2 The type and grade for the intended service shall be as
speciﬁed by the user with the assistance of the supplier where
desirable.
5.3 The purchaser shall be permitted to specify, inspect and

this shall be speciﬁed by the purchaser.
6. Materials and Manufacture
6.1 Composition—High temperature ﬁber thermal insulation
shall be composed of ﬁbers, made of metallic oxides of, but not
limited to, silicon, aluminum, calcium, and magnesium. The
raw materials, processed from the molten state into spun ﬁbers,
are then mechanically interlocked through a needling process
into insulation blanket felts with out the use of chemical
binders.
7. Physical and Mechanical, and Chemical Properties
Requirements
7.1 Apparent Thermal Conductivity shall conform to the
requirements of Table 2 when tested in accordance with 11.1.2.
7.2 Tensile Strength—shall conform to the requirements of
Table 3 when tested in accordance with 11.1.5.

mum of 30 % by weight when testing in accordance with
11.1.3.
7.6 Linear Shrinkage—shall be limited to a maximum of 5
%, after exposure to the Maximum Use Temperature, in
accordance with 11.1.4.
8. Dimensions, Mass, and Permissible Variations
8.1 Rolls or ﬂat sheets of blanket are normally furnished in
standard dimensions as shown in Table 4,Table 5, and Table 6.
8.2 The standard length, width, and thickness combinations
available are a function of the type and grade. Contact the
supplier for information on standard or non-standard dimen-
sion and combinations.
8.3 The maximum density (determined in accordance with
Test Method C167) speciﬁed in Table 4 for Grades 3, 4, 6, 8,
10, and 12 are for weight design purposes only.
9. Workmanship, Finish, and Appearance
9.1 The insulation shall indicate good workmanship in
fabrication by a uniform appearance, shall not have visible
defects such as tears and holes that will adversely affect the
service quality, and shall be free from foreign materials.
10. Sampling
10.1 The insulation shall be sampled for the purposes of test
in accordance with Practice C390. Speciﬁc provision for
sampling shall be agreed upon between the supplier and the
purchaser.
11. Test Methods
11.1 The properties enumerated in this speciﬁcation shall be
determined in accordance with the following test methods:
11.1.1 Dimensional Measurement and Density—Test Meth-
ods C167. Density is based on nominal thickness.
11.1.2 Apparent Thermal Conductivity—Test in accordance
with Test Method C177 or C201 (modiﬁed by the procedure
shown in Annex A1).
11.1.2.1 Practice C1058. shall be used to obtain recom-
mended test temperature combinations for testing purposes.
11.1.2.2 As speciﬁed in Practice C1045, the range of test
conditions must include at least one test where the hot surface
temperature is greater than, or equal to, the hot limit of the
temperature range of desired data and at least one test where
the cold surface temperature is less than, or equal to, the cold
limit of the temperature range desired. The exception to this
requirement is given in 11.1.2.2(1) below. At least two addi-
tional tests shall be distributed somewhat evenly over the rest
of the temperature range.
(1) In cases where the maximum temperature of the C177
test device is exceeded by the required hot surface temperature
as stipulated in 11.1.2.2, it is acceptable to operate one hot
plate at the C177 upper temperature limit and the other hot
plate at the lower temperature that gives the target mean
temperature.
11.1.2.3 Final analysis of the thermal data shall be con-
ducted in accordance with Practice C1045 to generate a

thermal conductivity versus mean temperature relationship for
the specimen. Practice C1045 and the speciﬁc hot and cold
surface temperatures is required to determine the effective
thermal conductivity for comparison to the speciﬁcation re-
quirements.
11.1.2.4 Final step of Practice C1045 analysis would be to
calculate the thermal conductivity using the equations gener-
ated at a set of mean temperatures for comparison to the
speciﬁcation.
(1) While it is recommended that the speciﬁcation data be
presented as conductivity versus temperature, it is possible that
several existing speciﬁcations will contain mean temperature
data from tests conducted at speciﬁc hot and cold surface
temperatures. In these cases, it is possible that the conductivity
will be a as a function of temperature and that the Practice
C1045 analysis will provide different results. To ensure that the
data is compatible, a Practice C680 analysis, using the con-
ductivity versus temperature relationship from Practice C1045
and the speciﬁc hot and cold surface temperatures, is required
to determine the effective thermal conductivity for comparison
to the speciﬁcation requirements.
11.1.3 Non-Fibrous Content (Shot)—Test Method C1335
Procedure B, with the following exceptions.
11.1.3.1 Use U.S. Standard Sieves No. 30, 50, and 70. The
specimen shall ﬁrst be ﬁred in a furnace at the maximum use
temperature for the particular Type for a duration of 5h. After
passing all particles and ﬁne ﬁber through Sieve No. 50,
mechanically shake Sieve No. 70 for 30 min.
11.1.3.2 For the purposes of this speciﬁcation, the non-
ﬁbrous content (that is, shot) are those not passing through a
U.S. Standard No. 70 sieve (210 µm opening). The shot content
is the cumulative weight of shot remaining on 30-, 50-, and
70-mesh screens.
11.1.4 Linear Shrinkage and Temperature of Use—Test
Method C356, except that dimensions shall be determined by
Test Methods C167. The temperature of test shall be the
temperature of use, as speciﬁed in 4.2.
11.1.5 Tensile Strength—Test Methods C209, Section 12
(parallel to surface), except that rate of separation of the jaws
shall be 1 to 2 in./min (25 to 50 mm/min).
