2、e 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 alloy a
3、nd 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 con
4、tinuously 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 E
5、1399.1.2 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 D 5048.1.3 The values stated in SI units are to be regarded as thestand
6、ard. 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 safety and health practices and determine the applica-
7、bility of regulatory limitations prior to use.2.
