scope:

1.1 This practice is for removing specimens from existing modified bitumen roof membranes for visual assessment and evaluation for abnormalities in the membrane. The roof membrane consists of one or more plies/sheet materials in which at least one ply is a modified bitumen (MB) sheet, and which is installed with one or more of the following methods: hot asphalt, heat welding (open flame torching or heated air), cold adhesive, or self-adhesive. The roof membrane may consist of one or more plies of the following:

1.1.1 SBS (styrene-butadiene-styrene), APP (attactic polypropylene), or other polymer, modified bitumen sheet materials.

1.1.2 An exposed modified bitumen sheet material, that is, a modified cap sheet, covering multiple layers of built-up roofing (BUR) plies.

1.1.3 Any adhesive or bitumen component used to install the roof membrane.

1.2 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.

1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
