ASTM C1763-19e1
(Test Method)Standard Test Method for Water Absorption by Immersion of Thermal Insulation Materials
Standard Test Method for Water Absorption by Immersion of Thermal Insulation Materials
SIGNIFICANCE AND USE
6.1 This test method provides a means of measuring the water absorption of flat specimens of thermal insulation materials under isothermal conditions as a result of direct immersion in liquid water. It is intended for quality control and product and material specifications.
6.2 The procedure to be used: A, B, or C as well as any exceptions shall be noted in material specifications citing this test method.
6.3 Repeatability has been established only for one type and size of material at one immersion duration.
Note 1: Specifications referring to this test method are encouraged to establish repeatability for specific materials, immersion duration, and dimensions for inclusion in this test method.
SCOPE
1.1 This test method determines the amount of water retained (excluding surface water) by flat specimens of thermal insulations after these materials have been fully immersed in liquid water for a prescribed time interval under isothermal conditions. This test method is intended to be used for the characterization of materials in the laboratory. It is not intended to simulate any particular environmental condition potentially encountered in building construction applications.
1.2 This test method does not address all the possible mechanisms of water intake and retention and related phenomena for thermal insulations. It relates only to those conditions outlined in 1.1. Determination of moisture accumulation in thermal insulations due to partial immersion, water vapor transmission, internal condensation, freeze-thaw cycling, or a combination of these effects requires different test procedures.
1.3 This test method does not address or attempt to quantify the drainage characteristics of materials.
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
1.5 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 appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

1.1 This test method determines the amount of water retained (excluding surface water) by flat specimens of thermal insulations
after these materials have been fully immersed in liquid water for a prescribed time interval under isothermal conditions. This test
method is intended to be used for the characterization of materials in the laboratory. It is not intended to simulate any particular
environmental condition potentially encountered in building construction applications.
1.2 This test method does not address all the possible mechanisms of water intake and retention and related phenomena for
thermal insulations. It relates only to those conditions outlined in 1.1. Determination of moisture accumulation in thermal
insulations due to partial immersion, water vapor transmission, internal condensation, freeze-thaw cycling, or a combination of

1.3 This test method does not address or attempt to quantify the drainage characteristics of materials.
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each
system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used
independently of the other, and values from the two systems shall not be combined.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility

2. Material And Specimen Characteristics that can Influence Results
2.1 The apparent water absorption measured by this test method is dependent on the surface to volume ratio of the sample and
time of immersion. As such, comparisons between Procedures A, B, and, C cannot be made. Cracks in the specimens and rough
surfaces can increase the apparent water absorption.
2.2 Some materials tend to collect water on surfaces or to trap water in corners and, if not removed, will give incorrect results.
2.3 Materials that change or react with water can have increased (or decreased) apparent water absorption and are not suitable
for use with this method. 12.5.1 provides a method for ensuring the specimen has not been physically or chemically altered in a
way that would invalidate the measurement. Use this method in cases of dispute.
