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.

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.

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.

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 inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

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 requirements prior to use.
