|Publication Date:||1 January 1983|
|ICS Code (Binders. Sealing materials):||91.100.50|
1.1 This practice is a guide for removing specimens from new built-up bituminous roof membranes prior to 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.
