1、Designation:C110314Standard 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 year of last
2、 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 ofinstalled precast concrete pipe sewer lines,when using eitherair or wa
3、ter under low pressure to demonstrate the integrity ofthe joint and the construction procedures.This practice is usedfor testing 27-in.and larger diameter precast concrete sewerlines utilizing rubber gasket sealed joints.NOTE1The user of this practice is advised that methods describedherein may also
4、 be used as a preliminary test to enable the manufactureror installer to demonstrate the condition of sewer pipe prior to delivery.1.2 This practice is the inch-pound companion to PracticeC1103M;therefore,no SI equivalents are presented in thepractice.NOTE2The owner shall specify the following:who w
5、ill conduct,observe,and furnish labor,material,and measuring devices and pay forthe tests;who is responsible for determining local ground conditions;andwhether an air or water test is to be used.NOTE3The user of this practice is advised that test criteria presentedin this practice are similar to tho
6、se in general use.Pipe shall be acceptedby infiltration or exfiltration testing utilizing Practice C969.NOTE4Test times tabulated and the rate of air loss in this practice arebased on successful testing of installed pipelines.However,since air andwater have different physical properties,retests of s
7、ome pipelines notmeeting field air tests have been successful when tested with water.1.3 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 d

9、st Concrete Pipe Sewer Lines3.Terminology3.1 DefinitionsFor definitions of terms relating to concretepipe,see Terminology C822.4.Summary of Practice4.1 The joint in the sewer line to be tested is covered on theinside of the pipe by a ring with two end element sealing tubes.Air or water,at low pressu
10、re,is introduced through a connec-tion on the ring into the annular space between the ring andjoint.The amount of air,or water,loss is used to determine theacceptability of the installed sewer line.5.Significance and Use5.1 This is not a routine test.The values recorded areapplicable only to the sew
11、er being tested and at the time oftesting.6.Safety Precautions6.1 The use of compressed air is dangerous if a sewer line isnot prepared properly and proper procedures are not followed.6.2 It is imperative that all pressures be relieved completelybefore the test apparatus is loosened for removal.6.3
12、Pressurizing lines for the two end element sealing tubesshall be separate from the lines for pressurizing the voidvolume created by the joint test apparatus.The pressuresrequired to seal the end element tubes shall be as specified bythe apparatus manufacturer,and are greater than the pressurerequire
13、d to test the joint.The line for pressurizing the voidvolume shall include a 6-psi pressure relief device to reducehazards and avoid overpressurization.7.Preparation of the Sewer Joint7.1 Check the size of access openings to ensure that the testapparatus will fit in the sewer line.7.2 Clean the join
14、t and interior joint surfaces to eliminatedebris prior to wetting and testing.NOTE5The user of this practice is advised that a wetted interiorsurface is desirable and will produce more consistent results.Air may passthrough the walls of dry pipe.This can be overcome by wetting the pipe.1This practic
