ASTM C1818-22

ABSTRACT This specification covers synthetic fiber reinforced concrete pipe (Syn-FRCP) of internal diameters 12-48 in., intended to be used for the conveyance of sewage, industrial wastes, and storm water and for the construction of culverts. Pipe furnished under this specification shall be designated as Class I, II, III, IV, or V. The corresponding strength requirements are prescribed, along with the criteria for the acceptability of the pipe design. This specification also covers the requirements for pipe design and manufacturing data to be provided by the manufacturer, as well as the corresponding test methods; material, design, and manufacturing practice requirements; physical requirements; repairs; inspection; certification; and product marking. SCOPE 1.1 This specification covers synthetic fiber reinforced concrete pipe (Syn-FRCP), intended to be used for the conveyance of sewage, industrial wastes, and storm water and for the construction of culverts. Note 1: Experience has shown that the successful performance of this product depends upon the proper selection of the pipe strength, the type of bedding and backfill, the care that the installation conforms to the construction specifications, and provision for adequate inspection at the construction site. This specification does not include requirements for bedding, backfill, the relationship between field load conditions and the strength designation of pipe, or durability under unusual environmental conditions. These requirements should be included in the project specification. Note 2: This product is a rigid pipe and it does not depend upon deflection (pipe stiffness) for additional support from the soil. Note 3: This standard requires long-term testing of Syn-FRCP in accordance with Section 9 that goes above and beyond what is typically required for steel reinforced concrete pipe, in order to evaluate the long-term material strength of the fiber-concrete matrix. 1.2 Units—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.
