1.1 这些测试方法涵盖了安装前测试陶土管的设备和技术。使用整根管道进行的试验确定了抗挤压和静水压力的能力。使用管道碎片进行的试验测量了管体的吸水量以及可能从中提取的酸溶性物质的数量。 注1: 以下标准也适用于粘土管，可参考以获取更多信息:实践 第12页 和试验方法 C828号 ; 规格 C425型 和 700加元 . 1.2 以英寸-磅单位表示的数值视为标准值。括号中给出的值是数学转换为SI单位，仅供参考，不被视为标准单位。 1.3 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制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 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。 =====意义和用途====== 4.1 含义和适用性- 本文要求的测试结果表明，陶土管在规范验收、设计目的、监管法规、制造控制和研究方面的适用性和可接受性。

1.1 These test methods cover the equipment for, and the techniques of, testing vitrified clay pipe prior to installation. Tests using whole pipe determines the resistance to crushing and hydrostatic forces. Tests using pipe fragments measure the amount of water absorption of the pipe body and the quantity of acid-soluble material that may be extracted from it. Note 1: The following standards also apply to clay pipe and can be referenced for further information: Practice C12 and Test Method C828 ; Specifications C425 and C700 . 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 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. ====== Significance And Use ====== 4.1 Meaning and Suitability— The tests called for herein, from their results, indicate the suitability and acceptability of vitrified clay pipe for specifications acceptance, design purposes, regulatory statutes, manufacturing control, and research.
