This specification covers composite ribbed steel pipe, precoated and polyethyene lined intended for use for gravity flow sanitary sewers, storm sewers, and other special applications such as water transmission pipe, rehabilitation pipe, slip line pipe, and irrigation pipe. Pipes shall be fabricated in full circular cross-section with helical lock seams and helical ribs projecting outwardly. Specimens cut from production pipe normal to and across the lock seam shall conform to the required values of tensile strength. The pipe shall conform to the required values of nominal inside diameter and sheet thickness. Joint connectors for composite ribbed steel pipe precoated and polyethylene lined shall be specified as soil tight, water-resistant, or watertight.1.1 This specification covers composite ribbed steel pipe, precoated and polyethylene lined intended for use for gravity flow sanitary sewers, storm sewers, and other special applications such as water transmission pipe, rehabilitation pipe, slip line pipe, and irrigation pipe where extra corrosion and abrasion resistance are required. The steel sheet used in the fabrication of the pipe has a polymer coating over a metallic coating of zinc on both sides. In addition, as the pipe is being fabricated, the ribs are filled with polyethylene and then a polyethylene liner is extruded onto the interior surface.1.2 The exterior polymer precoating provides extra protection of the steel against soilside corrosion, in addition to that provided by the metallic coating, and also provides a dielectric barrier for cathodic protection. The interior polymer precoating provides an adhesive layer between the galvanized steel and the polyethylene lining. The applied lining provides internal protection against corrosion, erosion, and abrasion. By filling the rib which has a deltoid shape (smaller at the opening in the pipe wall than at the bottom of the rib), the polyethylene is mechanically connected to the pipe wall and the polyethylene liner is then thermally bonded to the filled rib.1.3 This specification does not include requirements for bedding, backfill, or the relationship between earth cover load and sheet thickness of the pipe. Experience has shown that the successful performance of this product depends upon the proper selection of sheet thickness, type of bedding and backfill, controlled manufacture in the plant, and care in the installation. The installation procedure is described in Practice A798/A798M.1.4 This specification is applicable to orders in either inch-pound units as A978, or in SI units as A978M. Inch-pound units and SI units are not necessarily equivalent. SI units are shown in brackets in the text for clarity, but they are the applicable values when the material is ordered to A978M.1.5 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 and health practices and determine the applicability of regulatory limitations prior to use.

4.1 The inspection of installed thermoplastic storm and sewer pipe verifies proper installation of the product and establishes a baseline for comparison for further evaluation.4.2 This guide is useful as a reference by an owner in preparing project specifications and to identify, evaluate and interpret observations during post installation inspections of pipe.4.3 Field evaluations either remotely or with person entry should be made by an independent 3rd party engineering firm or duly appointed representative of the owner.1.1 This guide identifies pipeline components, recommended protocols and evaluation criteria to consider in the inspection and acceptance of installed thermoplastic pipe by either person-entry, or remote inspection.1.2 This guide is intended for installation related observations and assumes that pre-installation inspection has been completed and all final settlement of fill has occurred. Inspection should be a minimum of 30 days after installation. This inspection period could be increased to accommodate the installer’s warranty period, which is typically one year or greater.NOTE 1: Pipe types covered under this standard are typically installed under the AASHTO LRFD Bridge Construction Specifications or Practice D2321.1.3 It applies to the thermoplastic non-pressure gravity flow storm and sewer pipe manufactured in accordance with Specifications D3034, F679, F714, F794, F894, F949, F1803, F2306, F2435, F2562, F2648, F2763, F2764, F2881, F2947, F3123, ISO 21138, ISO 4435, ISO 8772 and ISO 8773. It may also be considered for use for any similar thermoplastic pipe products not covered by this list but with similar physical or performance characteristics if approved by the owner.1.4 Person entry is normally used unless extenuating circumstances preclude this type inspection by the engineer. Remote inspection is recommended for use for pipe diameters of 30 in. [750 mm] and smaller unless otherwise specified by owner or engineer. Person entry ultimately depends on the safety, size, and environmental consideration assessments by the engineer.1.5 Access of installed pipe for manual inspection should follow OSHA 29 CFR PART 1926 SUBPART AA or ISO 45001, or any other applicable regulations for confined space entry. 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 and health practices and determine the applicability of regulatory limitations prior to use.1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.1.7 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.1.8 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 thermoplastic elastomeric (TPE) gasket materials for preformed elastomeric gaskets used in shielded and non-shielded mechanical couplings for gravity flow drain, waste, and vent (DWV), sewer, sanitary, and storm plumbing systems. Couplings include those that join similar and dissimilar piping sizes and materials. Gaskets shall be made of virgin thermoplastic elastomeric compound containing only clean reworked thermoplastic elastomer material. Gasket materials shall conform to specified values of the following physical requirements: hardness, elongation, tensile strength, heat aging, tear strength, water absorption, ozone resistance, compression set, oil immersion in IRM 903 oil, and stretch test for spliced gaskets.1.1 This specification covers thermoplastic elastomeric (TPE) gasket materials for preformed elastomeric gaskets used in shielded and non-shielded mechanical couplings. These couplings are used in gravity flow drain, waste, and vent (DWV), sewer, sanitary, and storm plumbing systems. They include couplings to join similar and dissimilar piping sizes and material.1.2 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.1.3 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 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.

5.1 This specification establishes some the key factors which govern the interpretation of videoborescoping tubular products for a specific application. It is recognized that the requirements for one application may be very different than those of another. Therefore, the specification allows for the inspection to be customized for the application by the user by allowing the purchaser to specify parameters which may be important for the application.1.1 This standard covers guidelines for ordering and examining tubular products for sanitary applications by videoborescoping. This method uses movable camera probe at the end of a cable to examine the interior of a tubular product. The image is then transmitted to an external monitor for analysis. The method is normally used when inside surface imperfections, not normally detected by other nondestructive methods, may result in contamination of the product which is contained by the tubular product.1.2 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.1.3 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.
