A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTEUnits information was editorially corrected in September 2013.1. Scope1.1 This
3、specification covers the physical requirements forthe fully cured elastomeric alloy and the movement capabilitiesof preformed architectural compression seals used for sealingexpansion joints in buildings and parking structures. Thepreformed architectural compression seal is a rectangularelastomeric
4、extrusion, having an internal baffle system pro-duced continuously and longitudinally 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 E1399/E1399M.1.2
5、 This specification covers all colors of architecturalcompression seals.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other.
6、 Combiningvalues from the two systems may result in non-conformancewith the standard.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use.
