ASTM E1783/E1783M-24

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: E1783/E1783M − 96 (Reapproved 2017) E1783/E1783M − 24
Standard Specification for
Preformed Architectural Strip Seals for Buildings and
Parking Structures
This standard is issued under the fixed designation E1783/E1783M; the number immediately following the designation indicates the year
of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.
A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used
independently of the other, and values from the two systems shall not be combined.
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.
