1、Designation: E1783 96 (Reapproved 2009)Standard Specification forPreformed Architectural Strip Seals for Buildings andParking Structures1This standard is issued under the fixed designation E1783; the number immediately following the designation indicates the year oforiginal adoption or, in the case
2、of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers the physical requirements forthe fully cured elastomeric alloy and
3、the movement capabilitiesof preformed architectural compression seals used for sealingexpansion joints in buildings and parking structures. Thepreformed architectural strip seal is an elastomeric extrusion.This extrusion is either a membrane or tubular having aninternal baffle system produced contin
4、uously and longitudi-nally throughout the material. These extrusions are secured inor over a joint by locking rails or an end dam nosing material.The architectural strip seal is compressed and expanded by thismechanical or chemical attachment.NOTE 1Movement capability is defined in Test Method E1399
5、.1.2 This specification covers all colors of architectural stripseals.NOTE 2The products described in this specification are manufacturedfrom thermoplastic elastomers defined as “fully cured elastomeric alloys”in Test Method D5048.1.3 The values stated in SI units are to be regarded asstandard. The
6、values given in parentheses are mathematicalconversions to inch-pound units that are provided for informa-tion only and are not considered standard.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 st
7、andard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
