2、he case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers the physical requirements forthe fully cured elastomeric a
3、lloy and the movement capabilitiesof preformed architectural compression seals used for sealingexpansion joints in buildings and parking structures. Thepreformed architectural compression seal is a rectangularelastomeric extrusion, having an internal baffle system pro-duced continuously and longitud
4、inally throughout the material.The architectural compression seal functions under compres-sion and is usually chemically bonded in place with anadhesive.NOTE 1Movement capability is defined in Test Method E 1399.1.2 This specification covers all colors of architecturalcompression seals.1.3 The value
5、s stated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonly.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate saf
6、ety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
