6、tration or exfiltration quantities for an installed system aredependent upon many factors other than the connections between manholestructures and pipe, and allowable quantities must be covered by otherspecifications and suitable testing of the installed pipeline and system.1.2 The values stated in
7、either inch-pound units or SI unitsare to be regarded separately as standard. Within the text the SIunits are shown in brackets. The values stated in each systemmay not be exact equivalents: therefore, each system shall beused independently of the other. Combining values from thetwo systems may resu

Bolts, nuts, and other threaded itemsused with joining systems shall be zinc coated by one of thefollowing processes: hot-dip process as provided in Specifica-tion A153/A153M; electroplating process as provided in Speci-fication B633,
23、Class Fe/Zn 8; or mechanical process asprovided in Specification B695, Class 8.

24、ss Fe/Zn 25; or mechanical process asprovided in Specification B695, Class 25.NOTE 2Experience has shown that successful performance of thisproduct depends on the type of bedding and backfill and the care in thefield installation of the manhole or structure and connecting pipes. Theowner is cautione
25、d to require inspection at the construction site.5. Principles of Design5.1 The design of the connector shall be such that positiveseal is accomplished at two locations: (1) between the connec-tor and the wall of the manhole or structure and (2) between theconnector and the pipe.5.1.1 The seal betwe
26、en the connector and the wall of themanhole or structure shall be made by either mechanicalmeans, compression of the resilient material between theoutside surface of the pipe and the pipe opening in the wall ofthe manhole or structure, or by casting the connector integrallywith the wall of the manho
27、le or structure.5.1.2 The seal between the connector and the pipe shall bemade by mechanical means or by compression of the resilientmaterial against the outside of the pipe.5.1.3 Due to the corrugated outer wall of the pipe, resilientfiller rings are not prohibited from being used between the pipea
28、nd the connector to provide a seal.5.2 The connector shall be capable of maintaining aresilient, hydrostatic seal under the performance conditions inSection 7. Devices used to effect mechanical seals shallconform to the requirements specified in Section 4.5.3 If so fabricated, all pipe stubs install
29、ed to allow forfuture connection to the manhole or structure shall be mechani-cally restrained from movement by means of, and in additionto, the resilient connectors. Movement of these optional stubswill affect the results of the test.6. Basis of Acceptance6.1 For diameter 36 in. 900 mm and smaller,
30、 at least oneconnector shall be tested for each 6 in. 150 mm increment indiameter. For diameters larger than 36 in. 900 mm, at leastone connector shall be tested for each 12 in. 300 mmincrement in diameter.6.2 The acceptability of the resilient connector shall bedetermined by the results of the phys
31、ical tests prescribed in thisspecification, if and where required, and by inspection, todetermine whether the connector conforms to the specificationwith regards to design and freedom from defects.6.3 When requested, a current certification shall be fur-nished as the basis of acceptance. The certifi
32、cation shall consistof the connector manufacturers test report, or statement by themanufacturer, accompanied by a copy of the test results, thatthe resilient connector has been tested and inspected inaccordance with the provisions of Section 4 and Section 7.Each certification so furnished shall be s
33、igned by the connectormanufacturer or an authorized agent, such as an independentprofessional engineer, who has witnessed the testing.NOTE 3Certification shall be deemed current, if it represents presentdesign, and bears a date that is no more than five years older than thecurrent date.7. Test Metho
34、ds and Requirements7.1 Install a pipe(s) and the resilient connector(s) to betested in the base section of a manhole or structure. For jointsother than soil tight or silt tight, subject the assembly to theprescribed hydrostatic pressure in 7.2 at the centerline of theconnector for a period of 10 min
35、 for each test condition.Restrain the pipe against axial movement during the tests.NOTE 4The user of this specification is advised that all safetyrequirements and procedures should be reviewed prior to the test.7.2 There shall be no leakage under any of the followingconditions:7.2.1 Straight alignme
36、nt of the pipe(s) subjected to a hydro-static pressure of 10.8 psi 74 kPa for 10 min.7.2.2 Axial misalignment of the pipe(s). Upon completionof the test for straight alignment in 7.2.1 the pipe(s) shall beaxially deflected at least 7 in any direction and subjected to ahydrostatic pressure of 10.8 ps
37、i 74 kPa for 10 min.A1107/A1107M 1727.2.3 Deflection of pipe from loading. Upon completion ofthe test in 7.2.2, return pipes to straight alignment and apply aload to the pipe until the outside diameter of the pipe has beendeflected by 5%. The load shall be applied a distance ofone-half the pipe diam
38、eter from the manhole or structure wall.The deflection shall be calculated at the point where the load isapplied. Subject the pipe(s) and structure to a hydrostaticpressure of 10.8 psi 74 kPa for 10 min.7.2.4 For safety purposes and ease of set-up, pressure is notprohibited from being relieved while
39、 deflecting or loading testsections.7.3 Leakage shall be construed to mean freely drippingwater emanating at the interface between the connector andbase of the manhole structure, or the pipe; between theconnector and the filler rings; or through the body of theconnector and the filler rings; or thro
40、ugh the body of theconnector itself.8. Product Marking8.1 Each connector shall be marked legibly by the connectormanufacturer with his trade name and the size designation orpart number.8.2 Any additional markings or color designations shall beagreed upon by the pipe and connector supplier.9.
