ASTM D3909/D3909M-14

Standard Specification for Asphalt Roll Roofing (Glass Felt) Surfaced With Mineral Granules

ABSTRACT
This specification covers asphalt-impregnated and coated glass felt roll roofing surfaced on the weather side with mineral granules, for use as a cap sheet in the construction of built-up roofs. The glass felt shall be a thin porous sheet composed predominately of fine glass fibers uniformly deposited in a nonwoven pattern. It shall contain a water-insoluble agent and may be reinforced with random, or parallel oriented glass yarns, or both, which may be gathered or twisted, bonded or unbonded. The products shall meet physical property requirements as to pliability, mass loss and behavior on heating, moisture, and dimensions (width, mass, and area).
SCOPE
1.1 This specification covers asphalt-impregnated and coated glass felt roll roofing surfaced on the weather side with mineral granules, for use as a cap sheet in the construction of built-up roofs.  
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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
