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.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. 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 SI (metric) units are to be regarded as 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.
