1、Designation: C1103 14C1103 19Standard Practice forJoint Acceptance Testing of Installed Precast Concrete PipeSewer Lines1This standard is issued under the fixed designation C1103; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the
2、 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.1. Scope1.1 This practice covers procedures for testing the joints of installed precast concrete pipe sewer lines, when u
3、sing either airor water under low pressure to demonstrate the integrity of the joint and the construction procedures. This practice is used fortesting 27-in. and larger diameter precast concrete sewer lines utilizing rubber gasket sealed joints.NOTE 1The user of this practice is advised that methods
4、 described herein may also be used as a preliminary test to enable the manufacturer or installerto demonstrate the condition of sewer pipe prior to delivery.1.2 This practice is the inch-pound companion to Practice C1103M; therefore, no SI equivalents are presented in the practice.NOTE 2The owner sh
5、all specify the following: who will conduct, observe, and furnish labor, material, and measuring devices and pay for the tests;who is responsible for determining local ground conditions; and whether an air or water test is to be used.NOTE 3The user of this practice is advised that test criteria pres
6、ented in this practice are similar to those in general use. Pipe shall be accepted byinfiltration or exfiltration testing utilizing Practice C969.NOTE 4Test times tabulated and the rate of air loss in this practice are based on successful testing of installed pipelines. However, since air and waterh
7、ave different physical properties, retests of some pipelines not meeting field air tests have been successful when tested with water.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to esta
8、blish appropriate safety safety, health, and healthenvironmental practices and determine theapplicability of regulatory limitations prior to use.

Terminology3.1 DefinitionsFor definitions of terms relating to concrete pipe, see Terminology C822.4. Summary of Practice4.1 The joint in the sewer line to be tested is
11、 covered on the inside of the pipe by a ring with two end element sealing tubes.Air or water, at low pressure, is introduced through a connection on the ring into the annular space between the ring and joint. Theamount of air, or water, loss is used to determine the acceptability of the installed se
12、wer line.5. Significance and Use5.1 This is not a routine test. The values recorded are applicable only to the sewer being tested and at the time of testing.6. Safety Precautions6.1 The use of compressed air is dangerous if a sewer line is not prepared properly and proper procedures are not followed
13、.6.2 It is imperative that all pressures be relieved completely before the test apparatus is loosened for removal.1 This practice is under the jurisdiction of ASTM Committee C13 on Concrete Pipe and is the direct responsibility of Subcommittee C13.09 on Methods of Test.Current edition approved Nov.

United States16.3 Pressurizing lines for the two end element sealing tubes shall be separate from the lines for pressurizing the void volumecreated by the joint test apparatus. The pressures required to seal the end element tu
18、bes shall be as specified by the apparatusmanufacturer, and are greater than the pressure required to test the joint. The line for pressurizing the void volume shall includea 6-psi pressure relief device to reduce hazards and avoid overpressurization.7. Preparation of the Sewer Joint7.1 Check the si
19、ze of access openings to ensure that the test apparatus will fit in the sewer line.7.2 Clean the joint and interior joint surfaces to eliminate debris prior to wetting and testing.NOTE 5The user of this practice is advised that a wetted interior surface is desirable and will produce more consistent
20、results. Air may pass throughthe walls of dry pipe. This can be overcome by wetting the pipe.7.3 Review safety precautions in Section 6.8. Procedures8.1 The following procedures apply to testing with either air or water.8.1.1 Determine groundwater conditions surrounding the sewer line to be tested,
21、and select the type of test to be conducted.8.1.2 If the groundwater pressure is equal to or greater than the test pressure, and the sewer line or joint is not leaking, the sewerline or joint is acceptable in accordance with Practice C969 and no additional testing is required. If one or more joints
22、are leaking,but the total amount of leakage in the sewer line being tested is equal to, or less than, the allowable leakage rate established inaccordance with Practice C969, the line is acceptable and no additional testing is required provided visible leaks are repaired.Moisture or beads of water ap
23、pearing on the surface of the joint will not be considered as visible leakage.8.1.3 Review proper operation, safety, and maintenance procedures as provided by the manufacturer of the joint test apparatus.8.1.4 Move the joint test apparatus into the sewer line to the joint to be tested and position i
24、t over the joint. Make sure the endelement sealing tubes straddle both sides of the joint and the hoses are attached. For the water test, the bleed-off petcock must belocated at top dead center.8.1.5 Inflate end element sealing tubes with air in accordance with equipment and manufacturers instructio
25、ns.NOTE 6The user of this practice is advised that all test pressures are measured as gauge pressure, which is defined as any pressure greater thanatmospheric pressure. Since water produces a pressure of 0.43 psi for every foot of depth, test pressures must be increased to offset the depth ofgroundw
26、ater over the sewer line. If the groundwater level is 2 ft or more above the top of the pipe at the upstream end or if the pressure required forthe test is greater than 6-psi gauge, the joint test method shall not be used and the infiltration test may be used (see Practice C969).NOTE 7An air or wate
27、r reservoir shall be included in the joint test system. By maintaining a constant supply of air or water in a reservoir, continuouspumping of air or water is not required, and any variances in test equipment and joint space will be negated. The reservoir shall have a minimum volumeof 2.5 ft3.8.2 Joi
28、nt Air Test:8.2.1 Review procedures in 8.1.8.2.2 Pressurize the void volume with air to 3.5 psi greater than the pressure exerted by groundwater above the pipe. Allow theair pressure and temperature to stabilize before shutting off the air supply, and start of test timing.8.2.3 If pressure holds, or
29、 drops less than 1 psi in 5 s, the joint is acceptable. Practically, the test is a go/no go test.8.2.4 If the joint being tested fails, it shall be retested, or repaired if necessary, and retested, in accordance with this practice.8.2.5 After the joint test is completed, exhaust void volume, then ex
30、haust end element tubes prior to removal of apparatus.8.2.6 Use or failure of the joint air test shall not preclude acceptance by appropriate water infiltration and exfiltration testing(see Practice C969), or other means.8.3 Joint Water Test:8.3.1 Review procedures in 8.1.8.3.2 Introduce water into
31、void volume until water flows evenly from open petcock. Close the petcock and pressurize with waterto 3.5 psi above the pressure exerted by groundwater above the pipe. Shut off the water supply.8.3.3 If the pressure holds, or drops less than 1 psi in 5 s, the joint is acceptable. Practically, the te
32、st is a go/no go test.8.3.4 If the joint being tested fails, it shall be retested, or repaired if necessary, and retested, in accordance with this practice.8.3.5 After the joint test is completed, exhaust end element tubes which will automatically release the water from the voidvolume, prior to remo
33、val of apparatus.8.3.6 Use or failure of this joint water test shall not preclude acceptance by appropriate water infiltration or exfiltration testing(see Practice C969), or other means.9. Precision and Bias9.1 No justifiable statement is presently capable of being made either on precision or bias o
34、f these procedures since the testresults merely state whether this is in conformance to the criteria for success specified. Due to the sealing effects of groundwaterand internal flow on concrete sewer lines, the test conditions and results are not reproducible.C1103 192ASTM International takes no po
