Standard Practice for Testing Physical Properties of Friable Surfacing Materials

Importancia y uso:

4.1 The purpose of this practice is to provide test methods and performance criteria involving encapsulants for surfacing material on an asbestos abatement project in accordance with Practice E1368, including the application of encapsulants to the surfacing material as an abatement measure and the removal of existing encapsulated surfacing material.

4.1.1 Abatement projects involving application of encapsulants require coverage, penetration, and cohesion/adhesion tests to determine encapsulation requirements during project design, on test patches, and at conclusion of the project to determine completeness of abatement.

4.1.2 Removal projects requires penetration tests during project design on test patches to determine thicknesses of encapsulated and un-encapsulated surfacing material.

4.2 The test methods and performance criteria described in this practice may also be used during a Project Design Survey in accordance with Practice E2356 to provide information for preparing the plans and specifications for applying or removing the encapsulated surfacing material.

4.3 Asbestos-containing surfacing materials installed in buildings may include fireproofing, acoustical and decorative plaster, and soundproofing. Properties not directly addressed in this practice may be important and appropriate test methods should be considered.

4.4 The test methods described in this practice are designed to (1) determine the depth of penetration, or lack thereof, of the encapsulant into the matrix of the surfacing material, (2) determine the coverage of the encapsulant on the surfacing material, and (3) to determine the adhesive and cohesive properties of the encapsulated surfacing material.

4.5 Compliance with the acceptance criteria in this practice and with referenced specifications does not guarantee that the abatement project will pass the visual inspection for completeness of clean-up in Practice E1368, or that the project will pass final air sampling for clearance, as other factors besides encapsulant performance affect these outcomes.
