Significance and Use
4.1 Masonry specimens are sometimes removed as part of an assessment of the condition of masonry construction. Such specimens are commonly prepared for shipment to a laboratory where the specimens are assessed with visual techniques, petrographic techniques, or standard test methods. The process of selecting, removing, and shipping the specimens can have an effect on test results. This practice provides procedures for selecting, removing, and shipping masonry specimens removed from existing construction.
4.2 The selection and removal processes described in this practice are primarily intended for walls. Selection and removal of masonry specimens from locations other than walls requires user judgment in order to obtain appropriate specimens.
4.3 This practice also covers reporting of the selection, removal, and shipping processes. This information allows interested parties to assess the impact of these processes on test results.
4.4 This practice does not address the use of test results conducted on removed masonry specimens. This practice does not determine whether the removed masonry materials met original specification requirements.
1.1 This practice covers the process of selection, removal, and shipment of masonry specimens from existing construction that are intended for testing. These specimens can be either individual masonry units or assemblages. Assemblages are a portion of existing masonry, typically consisting of masonry units, mortar, grout, reinforcing steel, collar joint, and masonry accessories. The specimens may be taken from single- or multiple-wythe construction, or portions thereof. This practice also covers procedures for reporting as part of this process.
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 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.
1.3 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.
