1.1 本规程涵盖了使用渗水或渗滤验收极限测试已安装预制混凝土污水管道的程序，以证明安装材料和施工程序的完整性。 1.2 本实践是实践的SI伴侣 C969 . 注1: 业主应规定以下内容:谁将进行、观察和提供劳动力、提供材料和测量装置，并支付测试费用；谁负责确定当地地下水条件；以及要进行的测试，即渗透测试或渗出测试。 注2: 建议本规程的用户，本规程中提出的测试标准与一般使用的测试标准类似。当进行渗透测试时，可通过目视检查验收直径为600 mm或更大的管道。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，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====== 5.1 这不是例行测试。记录的数值仅适用于正在测试的下水道和测试时的下水道。

1.1 This practice covers procedures for testing installed precast concrete pipe sewer lines 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 SI companion of Practice C969 . 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, 600-mm diameter or larger, may be accepted by visual 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 and health 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.
