1、Designation: F2487 06 (Reapproved 2012) An American National StandardStandard Practice forInfiltration and Exfiltration Acceptance Testing of InstalledCorrugated High Density Polyethylene Pipelines1,2This standard is issued under the fixed designation F2487; the number immediately following the desi

2、gnation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by

3、 agencies of the Department of Defense.1. Scope1.1 This practice covers procedures for testing installednon-perforated, gasketed corrugated high-density polyethylene(HDPE) pipelines using either water infiltration or exfiltrationacceptance limits to demonstrate the integrity via the level ofleakage

4、of the installed materials, construction procedures andinstallation qualityvia the level of leakage. Pipe to be testedunder this practice shall include corrugated HDPE drainagepipe meeting the requirements of AASHTO M 252, AASHTOM 294 and Specification F2306/F2306M.NOTE 1The performance criteria spe

5、cified in this standard may beused for other plastic pipe products. The engineer, however, must assess ifthe testing procedures are adequate for the particular material andinstallation being considered.NOTE 2The user of this practice is advised that test criteria presentedin this practice are simila

6、r to those in general use. Pipe, 600-mm (24-in.)diameter or larger, may be accepted by visual inspection when testing forinfiltration.1.2 The values stated in SI units are to be regarded as thestandard. The values in parentheses are mathematical conver-sions to inch-pounds, which are provided for in

7、formationalpurposes only and are not considered standard.1.3 This test method shall be performed on lines after allconnections and service laterals have been plugged and bracedadequately to withstand the test pressures. The time betweencompletion of the backfill operations and testing shall bespecif

8、ied by the approving authority.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitatio

9、ns prior to use. The testingrequired under this standard necessitates operating in confinedspaces. The user must insure that all OSHA and local safetycodes are duly observed.2.

12、of Practice4.1 Determine the groundwater conditions surrounding thesection of pipeline to be tested and select the type of test to beconducted.4.2 For the infiltration test, the amount of water leaking intothe pipeline is measured, and the rate of infiltration is deter-mined. If the rate is less tha

13、n or equal to the allowable limit, thesection of pipe tested is acceptable.4.3 For the exfiltration test, the pipeline is filled with waterto the specified test head and the rate of water loss isdetermined. If the rate is less than or equal to the allowablelimit, the section of pipe tested is accept

17、tine test. The values recorded areapplicable only to the pipe being tested and at the time oftesting.6. Preparation of the Pipeline6.1 The pipe shall be free of debris prior to testing.6.2 The manholes, the ends of the branches, laterals, wyesand stubs to be included in the test shall be plugged. Al

18、l plugsshall be secured to prevent leakage blowout due to testingpressure.WarningThe test places extremely high forces onplugs used for sealing the pipeline for pressure testing. Plugsmust be properly blocked and braced against movement beforethe test begins.All confined space procedures shall be ob

19、servedduring preparation and conducting of this test. Under nocircumstances shall any persons be permitted inside the man-hole during pressure testing.7. Procedure7.1 Infiltration Testing:7.1.1 Conduct testing from manhole to manhole. The lengthof pipeline tested shall not exceed 213 m (700 ft).7.1.

20、2 Stop all dewatering operations and allow the ground-water to return to its normal level. Infiltration testing shall notbe used unless the groundwater level is at least 0.6 m (2 ft)above the crown of the pipe for the entire length of the testsection.7.1.3 Plug all pipe outlets discharging into the

21、upstreammanhole.7.1.4 Measure the groundwater elevation and determine theaverage head over the test section.7.1.5 Measure infiltration leakage at the outlet of the testsection. Because leakage allowances are small, measurementsare best made by either timing the filling of a small containerof known v

22、olume, or by directing flow into a container for aspecified time and measuring the content, or by using smallweirs.7.1.6 If the measured rate of leakage is less than or equal tothe allowable leakage in accordance with 8.1, the section ofpipeline tested is acceptable.7.1.7 If the test section fails,

23、the line shall be repaired andretested in accordance with this practice.7.2 Exfiltration Testing:7.2.1 Conduct testing from manhole to manhole. The lengthof pipeline tested shall not exceed 213 m (700 ft).7.2.2 Determine the groundwater elevation at both ends ofthe test section. If the groundwater l

24、evel is less than 0.6 m (2ft) above the crown of the pipe measured from the highestelevation of the pipeline, the exfiltration test shall be used.7.2.3 Plug all pipe outlets discharging into the upstreammanhole and the test section outlet. Fill the pipeline with water.7.2.4 At the upstream manhole t

25、he test head shall beestablished as minimum of 0.6 m (2 ft) above the crown of thepipe, or at least 0.6 m (2 ft) above existing groundwater,whichever is higher.7.2.5 Measure the leakage loss over a timed test period. Theminimum test period shall be 15 min and the maximum shallnot exceed 24 h.7.2.6 I

26、f the measured rate of leakage is less than or equal tothe allowable leakage, in accordance with 8.1, the section ofpipeline tested is acceptable.7.2.7 If the test section fails, the line shall be repaired andretested in accordance with this practice. The groundwaterelevation shall be redetermined p

27、rior to a second test and thetest head adjusted, if necessary, in accordance with 7.2.4.8. Leakage Criteria8.1 Leakage criteria for infiltration and exfiltration testingshall be determined by the owner based on their applicationand design requirements.NOTE 3If the hydrostatic head is expected to exc

28、eed the maximumpressure capacity of the joint, as specified in Specification D3212, thedesign engineer should review field conditions to determine if a specialjoint design is required to maintain the long-term integrity of the system.NOTE 4The current Environmental Protection Agencys (EPA) maxi-mum

29、leakage allowance specified for infiltration and exfiltration accep-tance for sanitary pipelines is 18.5 L/(mm of internal diameter) (km ofpipeline) (24 h) 200 gal/in/mi/day.9.
