ASTM D6924-03(2017)

Anotace textu normy ASTM D6924-03(2017) :

This specification covers the material requirements for preformed thermoplastic vulcanizate (TPV) elastomeric joint seals for bridges. The seal consists of a multiple-web design composed of a TPV 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. The physical properties for which the seals shall be tested on and conform accordingly to are tensile strength, elongation at break, hardness, oven aging, ozone resistance, low- and high-temperature recovery, and compression-deflection properties.
