This specification covers reinforced arch-shaped concrete pipe to be used for the conveyance of sewage, industrial wastes, storm water, and for the construction of culverts. Pipe manufactured according to this specification shall be of three classes identified as Class A-II, A-III, and A-IV. The reinforced concrete shall consist of cementitious materials, mineral aggregates, and water, in which steel has been embedded in such a manner that the steel and concrete act together. The pipe shall be designed to meet both the 0.01 in. crack and ultimate strength requirements determined by conducting plant load bearing tests, material tests, and inspection of manufactured pipe for visual defects and imperfections. The reinforcement, joint, and manufacture are detailed.1.1 This specification covers reinforced arch-shaped concrete pipe to be used for the conveyance of sewage, industrial wastes, storm water, and for the construction of culverts.1.2 This specification is the SI companion to Specification C506; therefore, no inch-pound equivalents are presented in this specification. Reinforced concrete pipe that conform to the requirements of Specification C506 are acceptable under this Specification C506M unless prohibited by the owner.NOTE 1: This specification is a manufacturing and purchase specification only, and does not include requirements for bedding, backfill, or the relationship between field load condition and the strength classification of pipe. However, experience has shown that the successful performance of this product depends upon the proper selection of the class of pipe, type of bedding and backfill, and care that the installation conforms to the construction specifications. The owner of the reinforced concrete pipe specified herein is cautioned that he must correlate the field requirements with the class of pipe specified and provide inspection at the construction site.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.

This specification covers acrylonitrile-butadiene-styrene (ABS) pipe produced by single extrusion in standard thermoplastic pipe dimension ratios and pressure rated for water. Included are criteria for classifying ABS plastic pipe materials and ABS plastic pipe, a system of nomenclature for ABS plastic pipe, and requirements and test methods for materials, workmanship, dimensions, sustained pressure, burst pressure, and extrusion quality. Methods of marking are also given. The products covered by this specification are intended for use with the distribution of pressurized liquids, which are chemically compatible with the piping materials. Requirements cover workmanship, dimensions and tolerances (outside diameters and wall thickness), sustained pressure, burst pressure, and impact.1.1 This specification covers acrylonitrile-butadiene-styrene (ABS) pipe produced by single extrusion in standard thermoplastic pipe dimension ratios and pressure rated for water (see Appendix X1). Included are criteria for classifying ABS plastic pipe materials and ABS plastic pipe, a system of nomenclature for ABS plastic pipe, and requirements and test methods for materials, workmanship, dimensions, sustained pressure, burst pressure, and extrusion quality. Methods of marking are also given.1.2 The products covered by this specification are intended for use with the distribution of pressurized liquids, which are chemically compatible with the piping materials. Consult with the manufacturer and local building codes before use in other applications. Due to inherent hazards associated with testing components and systems with compressed air or other compressed gases some manufacturers do not allow pneumatic testing of their products. Consult with specific product/component manufacturers for their specific testing procedures prior to pneumatic testing.NOTE 1: Pressurized (compressed) air or other compressed gases contain large amounts of stored energy, which present serious safety hazards should a system fail for any reason.NOTE 2: This specification addresses only pipe for use in above ground service. For buried service consult the manufacturer and local building codes.NOTE 3: Exposure to ultraviolet radiation over a long period of time may affect the physical properties of ABS pipe. Consult the manufacturer for recommendations for handling, storage, and installations that are not protected by insulation.1.3 Pipe meeting the requirements of this standard are not compatible with IPS sized DWV fittings. The ABS pipe covered in this standard is intended for pressure service and it shall be joined to pressure fittings. Non-pressure fittings, such as DWV fittings from any material (ABS, PVC, CPVC, etc.), are not acceptable for pressure applications.1.4 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.5 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 the specification.1.6 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.1.7 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.

1.1 This specification covers aluminum and aluminum-alloy extruded bars, rods, wires, profiles, and tubes in the aluminum alloys (Note 1) and tempers shown in Table 2. Note 1: Throughout this specification the use of the term alloy in the general sense includes aluminum as well as aluminum alloy. Note 2: For rolled or cold-finished bars and rods refer to Specification B211/B211M, for drawn seamless tube used in pressure applications, Specification B210/B210M, for structural pipe and tube, Specification B429/B429M, and for seamless pipe and tube used in pressure applications, Specification B241/B241M. Note 3: Pipe and tube products listed in this specification are intended for general purpose applications. This specification may not address the manufacturing processes, integrity testing, and verification required for fluid-carrying applications involving pressure. See Specification B210/B210M, B241/B241M, or both as appropriate for seamless pipe and tube used in fluid-carrying applications involving pressure. See Specification B234M, as appropriate, for use in surface condensers, evaporators, and heat exchangers. 1.2 Alloy and temper designations are in accordance with ANSI H35.1/H35.1M. The equivalent Unified Numbering System alloy designations are those of Table 1 preceded by A9, for example, A91100 for Aluminum 1100 in accordance with Practice E527. 1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2. 1.4 This specification is the metric counterpart of Specification B221. 1.5 The values stated in SI are to be regarded as standard. No other units of measurement are included in this specification. 1.6 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.
