Standard Specification for Asphalt Roll Roofing (Organic Felt)
ABSTRACT
This specification covers three classes and three types of asphalt roll roofing in sheet form, in widths agreed upon between the purchaser and the producer/supplier, and composed of asphalt-saturated organic felt coated on both sides with asphalt. Class M and WS rolls are surfaced on the weather (exposed) side with mineral granules, except for any selvage. Class S rolls are surfaced with powdered talc, mica, or other fine mineral matter to prevent sticking. Type classifications (Types II, III, and IV) are grouped based on minimum net mass per unit area of roofing. Roofing shall adhere to physical property requirements such as breaking strength, water permeance and vapor transmission, width, selvage, area, and moisture.
SCOPE
1.1 This specification covers asphalt roofing in sheet form, in widths agreed upon between the purchaser and the producer/supplier, composed of asphalt-saturated organic felt coated on both sides with asphalt. Class M and WS rolls are surfaced on the (exposed) weather side with mineral granules, except for any selvage. Class S rolls are surfaced with powdered talc, mica, or other fine mineral matter to prevent sticking.
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 nonconformance with the standard.
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
