Anotácia textu normy ASTM F1499-22 :
This specification covers co extruded composite drain, waste, and vent pipe (DWV). The pipe is produced in Schedule 40 IPS sizes by a co extrusion die system, in which the concentric layers are formed and combined before exiting the die. Coextruded composite drain, waste, and vent pipe, DWV, by definition, is permitted to be produced with two or more layers. The outer layer shall be ABS. The middle layer is permitted to be thermally foamed PVC or solid PVC or a blend of rework material, as specified. The inner layer is permitted to be solid PVC or ABS, or a blend of rework material as specified. The basic material used for pipes is a virgin compound which is used in the outer layer of co extruded composite drain, waste, and vent pipe or (DWV). It shall contain pigments or screening agents to provide protection against UV radiation. Different tests and measurements shall be conducted in order to determine the following properties of pipes: outside diameter, wall thickness, length, pipe flattening, pipe stiffness, impact strength, and bond. The inside and outside surfaces of pipe produced shall be free of chalking, sticky, or tacky material. The surfaces shall be free of excessive bloom. Bloom or chalking may develop in pipe exposed to direct rays of the sun (ultraviolet radiant energy) for extended periods and consequently, these requirements do not apply to pipe after extended exposure to direct rays of the sun. The inside and outside surfaces of pipe shall be free of foreign inclusion or other defects that re visible to the naked eye, and may affect the wall integrity.

1.1?This specification covers coextruded composite drain, waste, and vent pipe (DWV). The pipe is produced in Schedule 40 IPS sizes by a coextrusion die system, in which the concentric layers are formed and combined before exiting the die. 1.1.1?Coextruded composite drain, waste, and vent pipe, DWV, by definition, is permitted to be produced with two or more layers. The outer layer shall be ABS. The middle layer is permitted to be thermally foamed PVC or solid PVC or a blend of rework material, as specified in the rework material section. The inner layer is permitted to be solid PVC or ABS, or a blend of rework material as specified in the rework material section. 1.1.2?The function of this specification is to provide standardization of product, technical data, and serve as a purchasing guide. 1.2 DWV is permitted to be produced utilizing a two layer or three layer coextrusion die. 1.3?Materials that do not meet the requirements of the material section are excluded. 1.4?Pipe produced to this specification is permitted to be joined using molded fittings meeting the requirements of Specification D2661 or Specification F628. The fitting patterns must comply with Specification D3311. 1.5?Pipe produced to this specification is permitted to be perforated in accordance with any specified standard or by agreement between the purchaser and the supplier. 1.6?Pipe produced to this specification is permitted to be belled for joining by solvent cementing or belled for joining by an elastomeric seal (gasket), in accordance with any specified standard or by agreement between the purchaser and the supplier. 1.7?Recommendations for storage, joining, and installation are provided in Appendix X1, Appendix X2, and Appendix X3, respectively. 1.8?The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are for information only. 1.9?The text of this specification references notes, footnotes, and appendixes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this specification. Note 1:?Specifications related to this specification are as
follows: Specifications D2661, D2665, F628, and F891.
1.10?The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.11?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. 1.12?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. |
