(Specification)Standard Specification for Asphalt-Saturated Organic Felt Used in Roofing and Waterproofing
Standard Specification for Asphalt-Saturated Organic Felt Used in Roofing and Waterproofing
ABSTRACT
This specification covers asphalt-saturated organic felt used in roofing and waterproofing. Two types of asphalt-saturated felts are presented: type I - commonly called No. 15 asphalt felt, and type II - commonly called No. 30 asphalt felt. In the process of manufacture a single thickness of dry felt shall be saturated with an asphaltic saturant. The methods for the determination of openness of the perforations in saturated felts are presented in detail.
SCOPE
1.1 This specification covers asphalt-saturated organic felts, with or without perforations, intended to be used with asphalts conforming to the requirements of Specification D 312 in the construction of built-up roofs, and with asphalts conforming to the requirements of Specification D 449 in the construction of water proofing systems.
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 following safety hazards caveat pertains only to the test method portion, Section 8, of this specification: 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.
