1、Designation: C990M 09 (Reapproved 2014)Standard Specification forJoints for Concrete Pipe, Manholes, and Precast BoxSections Using Preformed Flexible Joint Sealants (Metric)1This standard is issued under the fixed designation C990M; the number immediately following the designation indicates the year
2、 oforiginal adoption or, in the case of revision, the 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 specification covers joints for precast concrete pi
3、peand box and other sections using preformed flexible jointsealants for use in storm sewers and culverts which are notintended to operate under internal pressure, or are not subjectto infiltration or exfiltration limits. Joint material used inhorizontal applications is intended to prevent the flow o
4、f solidsthrough the joint.1.2 Precast concrete manhole sections and other verticalstructures that are subject to internal or external pressure,infiltration, or exfiltration limits are not prohibited from beingspecified. Joints in vertical structures covered by this specifi-cation are intended mainly
5、 to prevent the flow of solids orfluids through the joint.1.3 This specification is to be used with pipe and structuresconforming in all respects to Specifications C14M, C76M,C478M, C506M, C507M, C655M, C985M, C1433M,C1504M, and C1577, provided that if there is a conflict inpermissible variations in
6、 dimensions, the requirements of thisspecification shall govern.1.4 This specification is the metric companion of Specifica-tion C990.NOTE 1This specification covers the material and performance of thejoint and sealant only. Infiltration and exfiltration quantities for installedsections are dependen
7、t on factors other than the joints which must becovered by other specifications and suitable testing of the installedpipeline.1.5 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 ap
