Scope This specification covers the quality of poly vinyl chloride (PVC), polyethylene (PE), high-density polyethylene (HDPE), and acrylonitrile-butadiene-styrene (ABS) plastic pipe, fittings, and joint materials. 2. Material Pipe—The pipe must be as uniform as commercially practicable in color, opaqueness, density, and other specified physical properties. It must be free from visible cracks, holes, foreign inclusions, or other defects. The dimensions of the pipe must be measured as prescribed in ASTM D2122. Unless otherwise specified, the pipe must conform to the requirements listed in this specification and the applicable reference specifications in table 547–2, the requirements specified in Construction Specification 45, Plastic Pipe, and the requirements shown on the drawings. Fittings and joints—Fittings and joints must be of a schedule, SDR or DR, pressure class, external load carrying capacity, or pipe stiffness that equals or exceeds that of the plastic pipe. The dimensions of fittings and joints must be compatible with the pipe and measured in accordance with ASTM D2122. Joint and fitting material must be compatible with the pipe material. The joints and fittings must be as uniform as commercially practicable in color, opaqueness, density, and other specified physical properties. They must be free from visible cracks, holes, foreign inclusions, or other defects. Fittings and joints must conform to the requirements listed in this specification, the requirements of the applicable specification referenced in the ASTM or AWWA specification for the pipe, the requirements specified in Construction Specification 45, and the requirements shown on the drawings.

  • Hydraulics Manual Glossary G - 3
    Glossary G - 1 GLOSSARY OF HIGHWAY-RELATED DRAINAGE TERMS (Reprinted from the 1999 edition of the American Association of State Highway and Transportation Officials Model Drainage Manual) G.1 Introduction This Glossary is divided into three parts: · Introduction, · Glossary, and · References. It is not intended that all the terms in this Glossary be rigorously accurate or complete. Realistically, this is impossible. Depending on the circumstance, a particular term may have several meanings; this can never change. The primary purpose of this Glossary is to define the terms found in the Highway Drainage Guidelines and Model Drainage Manual in a manner that makes them easier to interpret and understand. A lesser purpose is to provide a compendium of terms that will be useful for both the novice as well as the more experienced hydraulics engineer. This Glossary may also help those who are unfamiliar with highway drainage design to become more understanding and appreciative of this complex science as well as facilitate communication between the highway hydraulics engineer and others. Where readily available, the source of a definition has been referenced. For clarity or format purposes, cited definitions may have some additional verbiage contained in double brackets [ ]. Conversely, three “dots” (...) are used to indicate where some parts of a cited definition were eliminated. Also, as might be expected, different sources were found to use different hyphenation and terminology practices for the same words. Insignificant changes in this regard were made to some cited references and elsewhere to gain uniformity for the terms contained in this Glossary: as an example, “groundwater” vice “ground-water” or “ground water,” and “cross section area” vice “cross-sectional area.” Cited definitions were taken primarily from two sources: W.B.

  • Plastic Pipe Terms & Definitions
    PLASTIC PIPE TERMS & DEFINITIONS Every product has certain terms and definitions that are unique to that particular product. Listed below are some of the more common terms and definitions that relate to plastic pipe. A good understanding of these definitions is essential to understanding flexible pipe and future Info Briefs and Information Series. ASTM D 883 and F 412 define additional terms relating to plastic pipe. ACRYLONITRILE-BUTADIENE-STYRENE (ABS): Plastics containing polymers or blends of polymers, or both, in which the minimum butadiene content is 6%, the minimum acrylonitrile content is 15%, the minimum styrene or substituted content, or both, is 15%, and the maximum content of all other monomers is not more than 5%; plus lubricants, stabilizers and colorants. ADDITIVE: A substance added to another substance, usually to improve properties, such as plasticizers, initiators, light stabilizers, and flame retardants. AGING: The effects on materials of exposure to an environment for an interval of time. ASH CONTENT: Proportion of the solid residue remaining after a reinforcing substance has been incinerated (charred or intensely heated). BURST STRENGTH: The internal pressure required to cause a pipe or fitting to fail. CARBON BLACK: A black pigment produced by the incomplete burning of natural gas or oil. Because it possesses useful ultraviolet protective properties, it is also much used in molding compounds intended for outside weathering applications. CELL CLASSIFICATION: A rating of the primary properties of the resin material. To include density, melt index, flexural modulus, tensile strength at yield, environmental stress crack resistance, hydrostatic design basis, color and UV stabilizer. 208 Page 1 of 5 03/96 COEXTRUSION: A process whereby two or more heated or unheated plastic material streams forced through one or more shaping orifice(s) become one continuously formed piece.
