1、Designation:C1103M14Standard Practice forJoint Acceptance Testing of Installed Precast Concrete PipeSewer Lines(Metric)1This standard is issued under the fixed designation C1103M;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the ye
2、ar 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 ofinstalled precast concrete pipe sewer lines,when using eithe
3、rair or water under low pressure to demonstrate the integrity ofthe joint and the construction procedures.This practice is usedfor testing 675-mm and larger diameter precast concrete sewerlines utilizing rubber gasket sealed joints.NOTE1The user of this practice is advised that methods describedhere
4、in may also 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 SI companion of Practice C1103.NOTE2The owner shall specify the following:who will conduct,observe,and furnish labor,material,and mea
5、suring 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 those in general use.Pipe shall be acceptedby infiltratio
6、n or exfiltration testing utilizing Practice C969M.NOTE4Test times tabulated and the rate of air loss in this standard arebased on successful testing of installed pipelines.However,since air andwater have different physical properties,retests of some pipelines notmeeting field air tests have been su
7、ccessful 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 determine the applica-bility of regulatory limitations

9、gy3.1 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 pressure,is introduced through a connec-tion
10、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 sewer being tested and at the time oftesti
11、ng.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 Pressurizing lines for the two end elem
12、ent 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 pressurerequired to test the joint.The line for pressu
13、rizing the voidvolume shall include a 42 kPa 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 joint and interior joint surfaces to elimi
14、natedebris 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 may be overcome by wetting the pipe.1This practice is under the jurisdiction of ASTM Co
