【国外标准】 Standard Specification for Preformed Architectural Strip Seals for Buildings and Parking Structures

9.1 Architectural strip seals included in this specification shall be those:9.1.1 Extruded as a membrane,9.1.2 Extruded as tubular,9.1.3 With frames,9.1.4 With flanges mechanically secured,9.1.5 With flanges chemically secured,9.1.6 Used in interior or exterior applications, and9.1.7 Used in any construction of the building.9.2 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:9.2.1 The physical properties of the fully cured elastomeric alloy, and9.2.2 The movement capability in relation to the nominal joint width as defined under Test Method E1399/E1399M.9.3 This specification compares similar architectural strip seals but is not intended to reflect the system's application. “Similar” refers to the same type of architectural strip seal within the same subsection under 9.1.9.4 This specification does not provide information on the following:9.4.1 Durability of the architectural strip seal under actual service conditions, including the effects of cycled temperature on the strip seal;9.4.2 Loading capability of the system and the effects of a load on the functional parameters established by this specification;9.4.3 Shear and rotational movements of the specimen;9.4.4 Any other attributes of the specimen, such as fire resistance, wear resistance, chemical resistance, air infiltration, watertightness, and so forth; andNOTE 3: This specification addresses fully cured elastomeric alloys. Test Methods D395, D573, D1052, and D1149 are tests better suited for evaluating thermoset materials.9.4.5 Testing or compatibility of substrates.9.5 This specification is intended to be used as only one element in the selection of an architectural strip 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 durability, structural loading, and compatibility.AbstractThis specification covers the physical requirements and movement capabilities of preformed architectural strip seals for use in sealing expansion joints in buildings and parking structures. However, this specification does not provide information on the durability of the architectural strip seals under actual service conditions, loading capability of the system, and the effects of a load on the functional parameters. Material covered by this specification consists of architectural strip seals extruded as a membrane or tubular, with frames, with flanges mechanically or chemically secured, used in interior or exterior application, and used in any construction of the building. The architectural strip seal shall be manufactured from a fully cured elastomeric alloy as a preformed extrusion free of defects such as holes and air bubbles, and with dimensions conforming to the requirements specified. Tests for tensile strength, elongation at break, hardness, ozone resistance, compression set, heat aging, tear resistance, brittleness temperature, and water absorption shall be performed and shall conform to the requirements specified.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 strip seal is an elastomeric extrusion. This extrusion is either a membrane or tubular having an internal baffle system produced continuously and longitudinally throughout the material. These extrusions are secured in or over a joint by locking rails or an end dam nosing material. The architectural strip seal is compressed and expanded by this mechanical or chemical attachment.NOTE 1: Movement capability is defined in Test Method E1399/E1399M.1.2 This specification covers all colors of architectural strip seals.NOTE 2: The products described in this specification are manufactured from thermoplastic elastomers defined as “fully cured elastomeric alloys” in Test Method D5048.1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
