Standard Specification for Joints for Concrete Pipe, Manholes, and Precast Box Sections Using Preformed Flexible Joint Sealants

SCOPE
1.1 This specification covers joints for precast concrete pipe and box, and other sections using preformed flexible joint sealants for use in storm sewers and culverts which are not intended to operate under internal pressure, or are not subject to infiltration or exfiltration limits. Joint material used in horizontal applications is intended to prevent the flow of solids through the joint.
1.2 For precast concrete manhole sections and other vertical structures, which may be operated with internal or external pressure, infiltration or exfiltration limits may be specified. Joints in vertical structures covered by this specification are intended mainly to prevent the flow of solids or fluids through the joint.
1.3 This specification is to be used with pipe and structures conforming in all respects to Specifications C14, C76, C478, C506, C507, C655, C789, C850 and C985, provided that if there is a conflict in permissible variations in dimensions, the requirements of this specification shall govern.
1.4 This specification is the companion to SI specification C990M; therefore, no SI equivalents are shown in this specification.  
1.5 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Note 1—This specification covers the material and performance of the joint and sealant only. Infiltration and exfiltration quantities for installed sections are dependent on factors other than the joints which must be covered by other specifications and suitable testing of the installed pipeline.
