Scope

1.1 This practice is a guide for removing specimens from new built-up bituminous roof membranes 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 The values stated in SI (metric) units are to be regarded as the standard.

1.3 This standard is applicable to 910-mm (36-in.) wide felt rolls and does not apply to metric-sized (that is, 1000-mm [39 3/8-in.] wide) felt rolls.

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.
