1.1 本规范规定了用于微型隧道、先导管法、滑动衬砌、管道爆破以及污水、工业废物和雨水输送套管和隧道的玻璃化粘土顶管的制造、质量保证测试、检验、安装、现场验收测试和产品标记标准。 1.1.1 小节 3. 通过 7. 和 9 本规范的制造、质量保证测试、检验和产品标记标准适用于安装前的陶土管。 1.1.2 部分 8. 本规范包含了陶土管安装和现场验收测试的标准。 1.2 本规范还包括管道连接的材料和试验要求。 1.3 以国际单位制或英磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不完全相等；因此，每个系统应独立使用。组合两个系统的值可能导致不符合标准。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《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 establishes the criteria for the manufacture, quality assurance testing, inspection, installation, field acceptance testing, and product marking of vitrified clay jacking pipe to be used in microtunneling, the pilot tube method, sliplining, pipe bursting, and in casings and tunnels for the conveyance of sewage, industrial wastes, and storm water. 1.1.1 Sections 3 through 7 and 9 of this specification contain manufacturing, quality assurance testing, inspection, and product marking criteria which are applicable to vitrified clay pipe prior to installation. 1.1.2 Section 8 of this specification contains criteria for the installation and field acceptance testing of vitrified clay pipe. 1.2 This specification also covers materials and test requirements for jointing of the pipe. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. 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. 1.4 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. 1.5 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.
