1.1 This practice covers encapsulants intended to reduce or eliminate the release of asbestos fibers from a matrix of friable sprayor trowel-applied asbestos-containing surfacing material.
1.2 This practice includes a series of determinations to be conducted in the field on asbestos abatement projects for which encapsulation is being considered or has been performed.
1.3 This practice is to be used to determine the appropriateness of encapsulation as an abatement measure in accordance with Practice E1368, as part of a Project Design Survey in accordance with Practice E2356, and to demonstrate completeness of abatement in accordance with Practice E1368. Performance of the encapsulated surfacing material for other purposes is not within the scope of this practice. Use Test Methods E84, E119, and E605 to determine other properties of the material.
1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.
1.5 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.
1.6 Warning—Asbestos fibers are acknowledged carcinogens. Breathing asbestos fibers can result in disease of the lungs including asbestosis, lung cancer, and mesothelioma.2 Precautions in this standard practice should be taken to avoid creating and breathing airborne particles from materials known or suspected to contain asbestos. See
2.3 for regulatory requirements addressing asbestos.
1.7 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.
