This specification covers prefabricated, self-adhesive, glass fiber fabric reinforced, polymer-modified asphalt roll roofing, with granule surfacing, designed for steep slope applications. These products use polymer modifiers in their top and bottom coatings and have an adhesive bottom layer which is exposed by removal of a peel-away protective release paper or film sheet. The specified tests and property limits used to characterize the sheet materials are intended to establish minimum, or maximum properties. The minimum physical properties required for the sheet include thickness, peak load,1.1 This specification covers prefabricated, self-adhesive, glass fiber fabric reinforced, polymer-modified asphalt roll roofing, with granule surfacing, designed for steep slope applications. These products use polymer modifiers in their top and bottom coatings. These products have an adhesive bottom layer which is exposed by removal of a peel-away protective release paper or film sheet.1.2 The specified tests and property limits used to characterize the sheet materials are intended to establish minimum or maximum properties. In-place roof system design criteria such as fire resistance, field strength, impact/puncture resistance, material compatibility, uplift resistance, and others, are factors beyond the scope of this material specification. Factors regarding the suitability of specific roof constructions or application techniques are beyond this scope.1.3 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.1.4 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.1.5 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.

This specification covers melt processible molding and extrusion materials of modified ETFE-fluoropolymer. The ETFE resin is a copolymer of ethylene containing approximately 75 mass% of tetrafluoroethylene. This specification addresses virgin materials only as performance requirements cannot be met with recycled material. Modified ETFE-fluoropolymers shall be supplied in pellet form and classified into five types according to their specific gravity. Furthermore, the resins of each type are divided into three grades according to their melt flow rate. Materials shall be sampled, prepared, and conditioned as appropriate for testing, wherein the following performance requirements must be met: melting point and flow rate; melting endotherm peak temperature; specific gravity; tensile properties (tensile strength and elongation); and dielectric constant and dissipation factor.1.1 This specification covers molding and extrusion materials of modified ETFE fluoropolymer. The ETFE resin is a copolymer of ethylene and tetrafluoroethylene. Modified ETFE resin contains no more than 5 mole % of other fluoromonomers.1.2 The values stated in SI units as detailed in IEEE/ASTM SI-10 are to be regarded as standard. The values given in parentheses are for information only.NOTE 1: Although this specification and ISO 20568-1 and ISO 20568-2 differ in approach or detail, data obtained using either are technically equivalent.1.3 The following safety hazards caveat pertains only to the test method portion, Section 11, 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 Recycled material is not appropriate for this specification because performance requirements cannot be met with recycled material. Therefore, this specification is for virgin material only.1.5 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.

4.1 This test method is useful for indicating the relative coke-forming propensities and for evaluating and characterizing tars and pitches. This test method can also be used as one element in establishing the uniformity of shipments or sources of supply.1.1 This test method covers the determination of the coking value of tar and pitch having an ash content not over 0.5 % as determined by Test Method D2415.1.2 Coking values by this test method are practically the same as those obtained by Test Method D189, but results are more reproducible. The apparatus used is identical, except that an electric furnace is substituted for the gas flame.1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.4 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.1.5 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.
