    Abstract

    This specification covers finished and treated, woven glass fabrics coated with either asphalt, coal-tar pitch, or an organic resin compatible with the roofing, waterproofing, or other usage as specified by the purchaser. Asphalt treated Type I glass fabrics are suitable for use with all asphalts and asphalt based compounds. Coal tar pitch treated Type II glass fabrics, are suitable for use with all coal tar pitches and coal tar pitch based compounds. And finally, for organic resin treated Type III glass fabrics, the purchaser and supplier shall agree on an organic resin that is compatible with and/or suitable for the plying liquid plying materials either specified or to be used. This organic resin shall not be water soluble. Fabric specimens shall be appropriately sampled and tested, and consequently adhere to the following properties: thread count for both warp and filling threads; organic resin mass, width, length, area coverage, and mass; moisture present; and tensile strength.

    This abstract is a brief summary of the referenced standard.

    1. Scope

    1.1 This specification covers finished treated (coated) woven-glass fabrics coated with either asphalt, coal-tar pitch, or an organic resin compatible with the roofing, waterproofing, or other usage as specified by the purchaser.

    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 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.
