1. 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 Precast concrete manhole sections and other vertical structures that are subject to internal or external pressure, infiltration, or exfiltration limits are not prohibited from being 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 C14M, C76M, C478M, C506M, C507M, C655M, C985M, C1433M, C1504M, and C1577, 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 metric companion of Specification C990. 1.5 This standard does not
purport to address all of the safety concerns, 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.
