1.1 本规程涵盖了使用水渗透或渗出验收限值测试已安装的预制混凝土管下水道和检修孔的程序，以证明已安装材料和施工程序的完整性。 1.2 这种练习是练习的一寸一磅的伴侣 969米 ; 因此，在这种实践中没有SI等效物。 注1: 业主应明确以下内容:谁将进行、观察和提供劳动力，提供材料和测量设备，并支付测试费用；谁负责确定当地地下水状况；以及要进行哪种测试，即渗透测试或渗出测试。 注2: 建议本规程的使用者注意，本规程中提出的测试标准与一般使用的标准相似。在测试渗透性时，管道和人孔可以通过目视或视频检查来验收。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。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。 1.4 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》中确立的国际公认的标准化原则制定的。 =====意义和用途====== 5.1 这不是常规测试。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 installed precast concrete pipe sewer lines and manholes using either water infiltration or exfiltration acceptance limits to demonstrate the integrity of the installed materials and construction procedure. 1.2 This practice is the inch-pound companion to Practice C969M ; therefore, no SI equivalents are presented in this practice. Note 1: The owner shall specify the following: who will conduct, observe, and furnish labor, furnish material and measuring devices, and pay for the tests; who is responsible for determining local groundwater conditions; and which test is to be conducted, that is, an infiltration test or an exfiltration test. Note 2: The user of this practice is advised that test criteria presented in this practice are similar to those in general use. Pipe and manholes may be accepted by visual or video inspection when testing for infiltration. 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 ====== 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.
