(Specification)Standard Specification for Joints for Concrete Box, Using Rubber Gaskets
Standard Specification for Joints for Concrete Box, Using Rubber Gaskets
ABSTRACT
This specification covers flexible joints for concrete box sections, using rubber gaskets for leak resistant joints. The specification covers the design of joints and the requirements for rubber gaskets to be used. The gasket shall be fabricated from a rubber compound. The basic polymer shall be natural rubber, synthetic rubber, or a blend of both meeting the physical requirements prescribed. Gasket volume determination, non-circular shape gasket stretch height, and gasket length test methods shall be performed to determine the physical properties of the gastket in accordance with specified requirements. These test methods cover procedures for the mechanical testing of wrought and cast steels, stainless steels, and related alloys. Tension, bend, Rockwell hardness, portable hardness, brinell, and charpy impact tests shall be performed in accordance to specified requirements.
SCOPE
1.1 This specification covers flexible joints for concrete box sections, using rubber gaskets for leak resistant joints. The specification covers the design of joints and the requirements for rubber gaskets to be used therewith, for boxes conforming in all other respects to Specification C1433 or C1577, provided that if there is conflict in permissible variations in dimensions the requirements of this specification for joints shall govern.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
