ASTM C1262/C1262M-16

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 and health practices and determine the applicability of regulatory limitations prior to use.
