(Test Method)Standard Test Method for Evaluating the Freeze-Thaw Durability of Dry-Cast Segmental Retaining Wall Units and Related Concrete Units
Standard Test Method for Evaluating the Freeze-Thaw Durability of Dry-Cast Segmental Retaining Wall Units and Related Concrete Units
SIGNIFICANCE AND USE
4.1 The procedure described in this test method is intended to determine the effects of freezing and thawing on SRW and related units in the presence of potable tap water or saline solution.
4.2 The procedure is not intended to provide a quantitative measure to determine an expected length of service for a specific type of concrete unit.
Note 2: The testing laboratory performing this test method should be evaluated in accordance with Practice C1093.
SCOPE
1.1 This test method covers the resistance to freezing and thawing of dry-cast segmental retaining wall (SRW) units (see Specification C1372) and related concrete units. Units are tested in a test solution that is either potable tap water or 3 % saline solution depending on the intended use of the units in actual service.
Note 1: Related concrete units include units such as hollow and solid concrete masonry units, concrete brick, and concrete roof pavers.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with this standard. Some values have only SI units because the inch-pound equivalents are not used in practice.
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.

3.2 Definitions of Terms Specific to This Standard:
3.2.1 chamber capacity, n—the number of specimens contained within the test chamber during verification of chamber
temperatures and cycling.
3.2.1.1 Discussion—
The number of specimens in the chamber must remain the same at all times during testing. Chamber temperature cycling
verification must be performed at the chamber capacity that will be used during testing. If at any time during testing the actual
number of test specimens is less than the chamber capacity, dummy specimens must be used to maintain the same thermal load.
A change in chamber capacity requires verification of temperature cycling.
