1、Designation: D5973 97 (Reapproved 2017)Standard Specification forElastomeric Strip Seals with Steel Locking Edge Rails Usedin Expansion Joint Sealing1This standard is issued under the fixed designation D5973; the number immediately following the designation indicates the year oforiginal adoption or,
2、 in the case 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 material requirements forpreformed elastomeric str
3、ip seals and the corresponding steellocking edge rail used in expansion joint sealing. The scope ofthis specification is limited to preformed non-reinforced stripseals that mechanically lock into structural steel locking lugs.The sealing element can consist of a single layer strip or havemultiple we
4、bs depending on individual project requirements.The structural steel locking edge rail shall be anchored into thestructure in accordance with the purchasers specific details.While the scope of this specification is limited to the materialsused in fabrication of strip sealing systems, it is recommend
5、edthat a practical means of testing the watertightness aspects ofthe individual systems either in the field or at a testinglaboratory be developed. When used on highway bridges,limits on maximum joint opening and minimum steel thick-nesses need to be addressed.1.2 The values stated in the inch-pound
6、 system shall beconsidered as standard.1.3 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recom-mendations issued by the World

16、mmendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.14.3 The adhesive-lubricant used to install the preformed sealinto the steel locking edge rail shall be a one-part moisturecuring polyurethane compound. The watertightness of the sealshall not depend on th
17、e adhesive.5. Physical Properties5.1 The elastomeric seals shall conform to the physicalproperties prescribed in Table 1.5.2 The structural steel locking edge rail shall conform toSpecifications A588/A588M,5A36/A36M, A572/A572M,oras specified by the purchaser.5.3 The adhesive-lubricant shall conform
18、 to SpecificationD4070.6. Dimensions and Tolerances6.1 The size, shape, and dimensional tolerances shall be asagreed upon by the purchaser and the producer or supplier.These tolerances shall be in compliance with the RMA andsteel industry standards. The producer or supplier shall providethe purchase
19、r with acceptable tolerances on the seals and steelin the area where the seal fits into the steel locking edge rail,with the understanding that watertightness is not compromised.7. Workmanship7.1 The lug on the elastomeric strip seal shall be relativelyfree from dust, dirt, or other foreign material
20、s. This shall beaccomplished by wiping the lug that comes in contact with thesteel locking edge rail with a solvent, such as acetone. Thestandard factory unwashed finish is acceptable for all otherparts of the seal. Small dimples or surface imperfections areacceptable provided they are less than 0.1
21、25 in. (3.18 mm) indiameter and less than 5 % the depth of the cross-sectionalthickness. Talc residue is acceptable except in areas to bebonded.7.2 The steel locking edge rail shall be free of defects whichare detrimental to the performance of the system. A defect isdefined as fractures, tears, crac
22、ks, or other imperfections whichare greater than 5 % of the thickness of the steel at theirlocation. The steel cavity in contact with the elastomeric sealshall be free from dirt or other debris.8.
