Standard Specification for Preformed Polychloroprene Elastomeric Joint Seals for Bridges
ABSTRACT
This specification covers the material requirements for preformed polychloroprene elastomeric joint seals proposed for use in bridges. The multiple-web seals function by compression of the seal between the faces of the joint with the seal folding inward at the top. The seal is installed with a lubricant and is designed to seal the joint and reject incompressibles. The materials shall also conform to the physical properties prescribed herein such as tensile strength, elongation, hardness, ozone resistance, low-temperature recovery, high-temperature recovery, and compression-deflection properties.
SCOPE
1.1 This specification covers the material requirements for preformed polychloroprene elastomeric joint seals for bridges. The seal consists of a multiple-web design composed of polychloroprene and functions only by compression of the seal between the faces of the joint with the seal folding inward at the top to facilitate compression. The seal is installed with a lubricant adhesive and is designed to seal the joint and reject incompressibles. Note 1—This specification may not be applicable for seals whose height is less than 90 % of its nominal width.
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 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.
