(Test Method)Standard Test Method for Absorption of Architectural Cast Stone
Standard Test Method for Absorption of Architectural Cast Stone
SIGNIFICANCE AND USE
4.1 This test method is to be used in determining the absorption value of cast stone. Absorption is one measure of porosity of cast stone and, hence, its resistance to weathering and structural stress.
SCOPE
1.1 This test method covers the sampling and preparation of specimens for determining the absorption value of architectural cast stone.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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 appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 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. Scope
1.1 This test method covers the sampling, sampling and preparation of specimens, and determination of specimens for
determining the absorption value of architectural cast stone.
1.2 This test method describes two procedures: (1) cold water and (2) boiling water. The user of the test method should stipulate
which is desired. If no stipulation is made, the cold water procedure will be used.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and are not considered standard.
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 appropriate safety, health, and environmental practices and determine the applicability of
regulatory limitations prior to use.
1.4 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.

7. Conditioning
7.1 Oven dry specimens at a temperature of 230 6 9°F (110 6 5°C) until the loss in mass is not more than 0.1 % in 24 h of
drying. Remove specimens from the oven and allow to cool in room temperature to a final temperature of 68 to 77°F (20 to 25°C)
before testing for absorption.
8. Procedure

specimen).
