Standard Specification for Preformed Architectural Compression Seals for Buildings and Parking Structures

ABSTRACT
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.
SIGNIFICANCE AND USE
Architectural compression seals included in this specification shall be those as follows:
Without frames.
Without flanges and nosing material(s).
Used in interior or exterior applications.
Used in any construction of the building.
This specification will give users, producers, building officials, code authorities, and others a basis for verifying material and performance characteristics of representative specimens under common test conditions. This specification will produce data on the following:
The physical properties of the fully cured elastomeric alloy.
The movement capability in relation to the nominal joint width as defined under Test Method E1399.  
This specification compares similar architectural compression seals but is not intended to reflect the system's application. “Similar” refers to the same type of architectural compression seal within the same subsection under 8.1.
This specification does not provide information on the following:
Durability of the architectural compression seal under actual service conditions, including the effects of cycled temperature on the compression seal.
Loading capability of the system and the effects of a load on the functional parameters established by this specification.  
Shear and rotational movements of the specimen.
Any other attributes of the specimen, such as fire resistance, wear resistance, chemical resistance, air infiltration, watertightness, and so forth.
Testing or compatibility of substrates.
Strip seals.
Architectural compression seals used with frames.
Architectural compression seals used with flanges and nosing material(s).
This specification is intended to be used only as one element in the selection of an architectural compression seal for a particular application. It is not intended as an independent pass or fail acceptance procedure. Other standards shall be used in conjunction with this specification to evaluate the importance of other service conditions such as dur...
