1、Designation: F 2487 06Standard Practice forInfiltration and Exfiltration Acceptance Testing of InstalledCorrugated High Density Polyethylene Pipelines1, 2This standard is issued under the fixed designation F 2487; the number immediately following the designation indicates the year oforiginal adoptio

2、n or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Sc

3、ope1.1 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 of the installed materials, construction pro

4、cedures 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 F 2306/F 2306M.NOTE 1The performance criteria specified in this standard may beused for oth

5、er 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 similar to those in general use. Pipe, 600-mm (2

6、4-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 informationalpurposes only and are not consi

7、dered 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 bespecified by the approving authority.1.4 This st

8、andard 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 limitations prior to use. The testingrequired under

9、 this standard necessitates operating in confinedspaces. The user must insure that all OSHA and local safetycodes are duly observed.2.

12、ter 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 than or equal to the allowable limit, th

13、esection 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 acceptable.5. Significance and Use5.1 This

14、is not a routine test. The values recorded areapplicable only to the pipe being tested and at the time oftesting.1This practice is under the jurisdiction of ASTM Committee F17 on PlasticPiping Systems and is the direct responsibility of Subcommittee F17.20 on Joining.Current edition approved Dec. 15

Preparation of the Pipeline6.1 The

17、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. All plugsshall be secured to prevent leakage blowout due to testingpressure.WarningThe test places extremely high forces onplugs used for sea

18、ling the pipeline for pressure testing. Plugsmust be properly blocked and braced against movement beforethe test begins.All confined space procedures shall be observedduring preparation and conducting of this test. Under nocircumstances shall any persons be permitted inside the man-hole during press

19、ure 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).7.1.2 Stop all dewatering operations and allow the ground-water to return to its normal level. Infiltration testing shall notbe used unless the

20、 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 upstreammanhole.7.1.4 Measure the groundwater elevation and determine theaverage head over the test section.7.1.5 Measure infiltration leak

21、age at the outlet of the testsection. Because leakage allowances are small, measurementsare best made by either timing the filling of a small containerof known volume, or by directing flow into a container for aspecified time and measuring the content, or by using smallweirs.7.1.6 If the measured ra

22、te 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, the line shall be repaired andretested in accordance with this practice.7.2 Exfiltration Testing:7.2.1 Conduct testing from manhole to manh

23、ole. 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 level is less than 0.6 m (2ft) above the crown of the pipe measured from the highestelevation of the pipeline, the exfiltration test shall b

24、e 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 the 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

25、,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 If the measured rate of leakage is less than or equal tothe allowable leakage, in accordance with 8.1, the section ofpipeline tested is acce

26、ptable.7.2.7 If the test section fails, the line shall be repaired andretested in accordance with this practice. The groundwaterelevation shall be redetermined prior to a second test and thetest head adjusted, if necessary, in accordance with 7.2.4.8. Leakage Criteria8.1 Leakage criteria for infiltr

27、ation and exfiltration testingshall be determined by the owner based on their applicationand design requirements.NOTE 3If the hydrostatic head is expected to exceed the maximumpressure capacity of the joint, as specified in Specification D 3212, thedesign engineer should review field conditions to d

28、etermine if a specialjoint design is required to maintain the long-term integrity of the system.NOTE 4The current Environmental Protection Agencys (EPA) maxi-mum leakage allowance specified for infiltration and exfiltration accep-tance for sanitary pipelines is 18.5 L/(mm of internal diameter) (km o
