ASTM D3542-08(2019)

Anotace textu normy ASTM D3542-08(2019) :

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.
