This specification covers the physical requirements for the fully cured elastomeric alloy and the 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, having an internal baffle system produced continuously and longitudinally throughout the material. The architectural compression seal functions under compression and is usually chemically bonded in place with an adhesive. The architectural compression seal shall be a preformed extrusion manufactured from a fully cured elastomeric alloy, which shall be classified either M2CE 706 A16B15C12C20F19Z1Z2, or M2CE 708 A16B15C12C20F19Z1Z2. Materials shall be tested and the individual grades shall conform to the specified values of tensile strength, elongation at break, hardness, specific gravity, modulus, weight gain, ozone resistance, compression set, heat aging, ultimate tensile strength and elongation, tear resistance, brittleness temperature, water absorption, and movement capabilities. Workmanship, color, and appearance are also detailed.

1.1 This specification covers the physical requirements for the fully cured elastomeric alloy and the 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, having an internal baffle system produced continuously and longitudinally throughout the material. The architectural compression seal functions under compression and is usually chemically bonded in place with an adhesive. Note 1-Movement capability is defined in Test Method E 1399.

1.2 This specification covers all colors of architectural compression seals.

1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.4 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.
