1.1 本规范涵盖用于雨水排放、地下排水沟、涵洞施工和类似用途的波纹钢管。本规范涵盖的管道通常不用于运输生活或工业废物。用于制造管道的钢板具有锌（镀锌）、铝、55的保护性金属涂层 % 铝锌合金或锌-5 % 混合稀土铝合金。 1.2 几种不同的金属涂层可能无法在所有环境中或同时在两种环境中为基底金属提供同等的防腐或耐磨保护。某些环境可能非常恶劣，本规范中包含的任何金属涂层都无法提供足够的保护。波纹钢管的额外保护可通过使用规范中所述的管道制造后涂覆的涂层来提供 A849 或使用规范中所述的聚合物预涂层波纹钢管 A762/A762M . 1.3 部分 9 适用于波纹钢管接头。几种不同类型的波纹钢管接头具有不同的质量。本规范不适用于常规质量控制测试或现场验收测试，但旨在确定管道接头的性能极限，以及本文所述接头的测试要求和测试方法。 1.4 本规范不包括垫层、回填要求，也不包括覆土荷载和管道板厚之间的关系。经验表明，该产品的成功性能取决于板材厚度、垫层和回填类型的正确选择、工厂的受控制造以及安装过程中的谨慎。 安装程序在实践中进行了描述 A798/A798M . 1.5 本规范适用于以下任一英寸-磅单位的订单: A760 或以国际单位制表示 A760米 . 英寸磅单位和国际单位不一定相等。为清楚起见，文本中的括号中显示了国际单位制，但在订购材料时，这些单位是适用的值 A760米 . 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This specification covers corrugated steel pipe intended for use for storm water drainage, underdrains, the construction of culverts, and similar uses. Pipe covered by this specification is not normally used for the conveyance of sanitary or industrial wastes. The steel sheet used in fabrication of the pipe has a protective metallic coating of zinc (galvanizing), aluminum, 55 % aluminum-zinc alloy, or zinc-5 % aluminum-mischmetal alloy. 1.2 The several different metallic coatings may not provide equal protection of the base metal against corrosion or abrasion in all environments, or both. Some environments may be so severe that none of the metallic coatings included in this specification will provide adequate protection. Additional protection for corrugated steel pipe can be provided by use of coatings applied after fabrication of the pipe as described in Specification A849 , or by use of polymer precoated corrugated steel pipe as described in Specification A762/A762M . 1.3 Section 9 is intended to be applied to corrugated steel pipe joints. The several different types of corrugated steel pipe joints provide various qualities. This specification is not intended for routine quality control testing or in-field acceptance testing, but is intended to establish performance limits of the pipe joints, as well as the test requirements and test methods for the joints as described herein. 1.4 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 . 1.5 This specification is applicable to orders in either inch-pound units as A760 or in SI units as A760M . 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 A760M . 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.
