Summary of Practice4.1 Determine the groundwater conditions surrounding the section of pipeline to be tested and select the type of test to
20、beconducted.4.2 For the infiltration test, the amount of water leaking into the pipeline is measured, and the rate of infiltration is determined.If the rate is less than or equal to the allowable limit, the section of pipe tested is acceptable.4.3 For the exfiltration test, the pipeline is filled wi
21、th water to the specified test head and the rate of water loss is determined.If the rate is less than or equal to the allowable limit, the section of pipe tested is acceptable.5. Significance and Use5.1 This is not a routine test. The values recorded are applicable only to the pipe being tested and
22、at the time of testing.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, wyes and stubs to be included in the test shall be plugged. All plugs shallbe secured to prevent leakage blowout due to testing pressure.Wa
23、rningThe test places extremely high forces on plugs used forsealing the pipeline for pressure testing. Plugs must be properly blocked and braced against movement before the test begins. Allconfined space procedures shall be observed during preparation and conducting of this test. Under no circumstan
24、ces shall anypersons be permitted inside the manhole during pressure testing.7. Procedure7.1 Infiltration Testing:7.1.1 Conduct testing from manhole to manhole. The length of pipeline tested shall not exceed 213 m (700 ft).7.1.2 Stop all dewatering operations and allow the groundwater to return to i
25、ts normal level. Infiltration testing shall not be usedunless the groundwater level is at least 0.6 m (2 ft) above the crown of the pipe for the entire length of the test section.7.1.3 Plug all pipe outlets discharging into the upstream manhole.7.1.4 Measure the groundwater elevation and determine t
26、he average head over the test section.7.1.5 Measure infiltration leakage at the outlet of the test section. Because leakage allowances are small, measurements are bestmade by either timing the filling of a small container of known volume, or by directing flow into a container for a specified timeand
27、 measuring the content, or by using small weirs.7.1.6 If the measured rate of leakage is less than or equal to the allowable leakage in accordance with 8.1, the section of pipelinetested is acceptable.7.1.7 If the test section fails, the line shall be repaired and retested in accordance with this pr
28、actice.7.2 Exfiltration Testing:7.2.1 Conduct testing from manhole to manhole. The length of pipeline tested shall not exceed 213 m (700 ft).7.2.2 Determine the groundwater elevation at both ends of the test section. If the groundwater level is less than 0.6 m (2 ft)above the crown of the pipe measu
29、red from the highest elevation of the pipeline, the exfiltration test shall be used.7.2.3 Plug all pipe outlets discharging into the upstream manhole and the test section outlet. Fill the pipeline with water.7.2.4 At the upstream manhole the test head shall be established as minimum of 0.6 m (2 ft)
30、above the crown of the pipe, orat least 0.6 m (2 ft) above existing groundwater, whichever is higher.7.2.5 Measure the leakage loss over a timed test period. The minimum test period shall be 15 min and the maximum shall notexceed 24 h.7.2.6 If the measured rate of leakage is less than or equal to th
31、e allowable leakage, in accordance with 8.1, the section of pipelinetested is acceptable.7.2.7 If the test section fails, the line shall be repaired and retested in accordance with this practice. The groundwater elevationshall be redetermined prior to a second test and the test head adjusted, if nec
32、essary, in accordance with 7.2.4.8. Leakage Criteria8.1 Leakage criteria for infiltration and exfiltration testing shall be determined by the owner based on their application anddesign requirements.F2487 132NOTE 3If the hydrostatic head is expected to exceed the maximum pressure capacity of the join
33、t, as specified in Specification D3212, the designengineer should review field conditions to determine if a special joint design is required to maintain the long-term integrity of the system.NOTE 4The current Environmental Protection Agencys (EPA) maximum leakage allowance specified for infiltration
34、 and exfiltration acceptance forsanitary pipelines is 18.5 L/(mm of internal diameter) (km of pipeline) (24 h) 200 gal/in/mi/day.9.
