This specification covers requirements and test methods for materials, dimensions, workmanship, ring stiffness, flattening, joint systems, and a form of marking for polyethylene (PE) pipe of profile wall construction and with bell and spigot, heat fusion, extrusion welded or electrofusion joints for use in gravity flow applications, such as for sewers and drains. The PE profile wall pipe products cover six standard ring stiffness constant (RSC) classifications, namely 40, 63, 100, and 160, 250 and 400. These are referred to as RSC 40, RSC 63, RSC 100, RSC 160, RSC 250 and RSC 400. Referee testing, ring stiffness constant testing, flattening test, and joint tightness test shall be performed to meet the requirements prescribed.1.1 This specification covers requirements and test methods for materials, dimensions, workmanship, ring stiffness, flattening, joint systems, and a form of marking for large diameter, 10 to 132 in. (250 to 3355 mm), inside diameter based polyethylene (PE) pipe of profile wall construction and with bell and spigot, heat fusion, extrusion welded or elctrofusion joints for use in gravity flow applications, such as for sewers and drains.NOTE 1: Pipe produced to this specification should be installed in accordance with Practice D2321 and with the manufacturer's recommendations.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 The following safety hazards caveat pertains only to the test method portion, Section 8, 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 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 guide covers standard specification for straight seam or spinal seam electric-fusion-welded, light-wall, austenitic chromium-nickel alloy steel pipe for corrosive or high-temperature service. The sizes covered shall include NPS 14 to 30 with extra light (Schedule 5S) and light (Schedule 10S) wall thickness. Several grades of alloy steel shall be covered and shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, titanium, columbium, cerium, and other elements. The chemical composition of the welding filler metal shall also conform to the requirements of the applicable AWS specification for the corresponding grade. Tensile properties of the plate or sheet used in making the pipe shall conform to the prescribed values of tensile strength and yield strength. Mechanical tests such as tension test and transverse guided-bend weld test shall be conducted. Pressure or nondestructive electric test shall also be performed.1.1 This specification2 covers straight seam or spiral seam electric-fusion-welded, light-wall, austenitic chromium-nickel alloy steel pipe for corrosive or high-temperature service. The sizes covered are NPS 14 to 30 with extra light (Schedule 5S) and light (Schedule 10S) wall thicknesses. Table X1.1 shows the wall thickness of Schedule 5S and 10S pipe. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specification.1.2 Several grades of alloy steel are covered as indicated in Table 1.1.3 Optional supplementary requirements are provided. These call for additional tests to be made, and when desired shall be stated in the order, together with the number of such tests required.1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. 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 non-conformance with the standard. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.NOTE 1: The dimensionless designator NPS (nominal pipe size) has been substituted in this standard for such traditional terms as nominal diameter, size, and nominal size.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.
