ASTM E1612/E1612M-94 (R2017) PDF Download

ASTM E1612/E1612M-94 (R2017) is a standard specification that outlines the physical requirements and movement capabilities of preformed architectural compression seals used for sealing expansion joints in buildings and parking structures. The preformed architectural compression seal is a rectangular elastomeric extrusion with an internal baffle system produced continuously and longitudinally throughout the material. The seal is designed to function under compression and is typically bonded in place with an adhesive.

The standard specifies that the architectural compression seal should be manufactured from a fully cured elastomeric alloy, which falls under two possible classifications. It provides guidelines for testing the materials, including tensile strength, elongation at break, hardness, specific gravity, modulus, ozone resistance, compression set, heat aging, tear resistance, brittleness temperature, water absorption, weight gain, and movement capabilities.

The document also outlines the types of architectural compression seals included in the specification, such as those without frames, flanges, and nosing materials, and those used in interior or exterior applications. It emphasizes that this specification serves as a basis for verifying material and performance characteristics under common test conditions.

However, the standard does not provide information on the durability of the architectural compression seal under actual service conditions, loading capability, shear and rotational movements, or attributes such as fire resistance, wear resistance, chemical resistance, air infiltration, and watertightness. It also does not cover compatibility with substrates or address the use of strip seals, frames, and flanges.
