ASTM C1587/C1587M-21a

Standard Practice for Preparation of Field Removed Manufactured Masonry Units and Masonry Specimens for Testing

SIGNIFICANCE AND USE
4.1 Masonry units and masonry specimens are sometimes removed as part of an assessment of the condition of masonry construction. This standard is intended to standardize the preparation of such units and masonry specimens for compressive and flexural bond strength testing.
Note 1: Masonry specimens removed from existing masonry construction (single wythe, multi-wythe or portions thereof) will sometimes contain mortar, grout, reinforcement, or accessory materials.  
4.2 This practice provides information pertaining to the removal of hardened mortar, cleaning, and other special preparation required prior to compressive and flexural bond strength testing of a manufactured masonry unit or masonry specimen that has been removed from usage.  
4.3 This practice does not address test procedures or the use of test results conducted on removed specimens. This practice does not determine whether removed masonry materials met original specification requirements.
Note 2: Compressive and flexural bond strength test results of masonry units and masonry specimens extracted from the field are expected to vary from and will likely be less than test results of masonry units that have not been placed in service or masonry prisms that have been constructed within a controlled environment. Comparison of results of tests conducted on specimens removed from service to those of masonry units prior to use or of constructed prisms is difficult. Considerable judgment is typically required for the selection and preparation of specimens removed from service.
SCOPE
1.1 The purpose of this practice is to standardize the preparation of manufactured masonry units and masonry specimens extracted from the field for compressive and flexural bond strength testing in a laboratory environment.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The inch-pound units are shown in brackets. 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 the 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.
