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.
