Abstract:

This practice describes the standard procedure for sampling, analysis, and removal of specimens in built-up bituminous roof systems during application, but before the application of flood coating and top surfacing, for determining the approximate quantities of the components and the possible presence of moisture, or dry spots between plies, in the field. These components may be composed of insulation (when part of the roof membrane system), plies of roofing felt, interply layers of bituminous material, and top coating (if present, before any surfacing aggregate has been applied). Appropriate calculation procedures are also indicated herein.

Scope:

1.1 This practice is a guide for removing specimens for built-up bituminous roof systems during application, but before the application of flood coating and top surfacing, for determining the approximate quantities of the components and the possible presence of moisture, or dry spots between plies, in the field. Components may consist of:

1.1.1 Insulation, when part of the roof membrane system,

1.1.2 Plies of roofing felt,

1.1.3 Interply layers of bituminous material, and

1.1.4 Top coating, if present, before any surfacing aggregate has been applied.

1.2 This practice is applicable to both 914-mm [36-in.] and 1000-mm [39 3/8-in.] wide felt rolls.

1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. 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.

1.4 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 limitations prior to use.
