1.1 本规程涵盖了在低压下使用空气或水来证明接头和施工程序的完整性时，测试已安装的预制混凝土管道下水道接头的程序。本规程用于测试使用橡胶垫圈密封接头的预制混凝土下水道。 注1: 建议本实践的用户，此处描述的方法也可以用作初步测试，以使制造商或安装人员能够在交付前证明污水管的状况。 1.2 以英寸磅单位表示的值应视为标准值。括号中给出的值是对SI单位的数学转换，仅供参考，不被视为标准。 注2: 业主应指定以下人员:谁将进行、观察和提供劳动力、材料和测量设备，并支付测试费用；谁负责确定当地地面条件；以及是否使用空气或水测试。 注3: 建议本实践的用户，本实践中提出的测试标准与一般使用的测试标准相似。 管道应通过渗透或渗出试验进行验收 约969 ( 约9.69亿 ). 注4: 本规程中列出的试验时间和空气损失率基于已安装管道的成功试验。然而，由于空气和水具有不同的物理性质，当用水进行测试时，对一些不符合现场空气测试要求的管道进行的重新测试是成功的。 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。 具体预防措施见第节 6. . 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====== 5.1 这不是例行测试。记录的值仅适用于正在测试的下水道和测试时。

1.1 This practice covers procedures for testing the joints of installed precast concrete pipe sewer lines, when using either air or water under low pressure to demonstrate the integrity of the joint and the construction procedures. This practice is used for testing precast concrete sewer lines utilizing rubber gasket sealed joints. Note 1: The user of this practice is advised that methods described herein may also be used as a preliminary test to enable the manufacturer or installer to demonstrate the condition of sewer pipe prior to delivery. 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. Note 2: The owner shall specify the following: who will conduct, observe, and furnish labor, material, and measuring devices and pay for the tests; who is responsible for determining local ground conditions; and whether an air or water test is to be used. Note 3: The user of this practice is advised that test criteria presented in this practice are similar to those in general use. Pipe shall be accepted by infiltration or exfiltration testing utilizing Practice C969 ( C969M ). Note 4: Test times tabulated and the rate of air loss in this practice are based on successful testing of installed pipelines. However, since air and water have different physical properties, retests of some pipelines not meeting field air tests have been successful when tested with water. 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. Specific precautions are given in Section 6 . 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 ====== 5.1 This is not a routine test. The values recorded are applicable only to the sewer being tested and at the time of testing.
