1、Designation: D5973 97 (Reapproved 2012)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.2.

United States15.2 The structural steel locking edge rail shall conform toSpecifications A588/A588M,5A36/A36M, A572/A572M,orasspecified by the purchaser.5.3 The adhesive-lubricant shall conform to SpecificationD4070.6. Dimensions and
16、 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 purchaser with acceptable tolerances on the seal
17、s 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 materials. This shall beaccomplished by wiping th
18、e 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 0.125 in. (3.18 mm) indiameter and less than
19、 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, cracks, or other imperfections whichare great
20、er 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. Sampling8.1 A lot shall consist of the quantity of elastomeric sealagreed upon by the purchaser and the producer or supplier.8.2 Samples of the
21、elastomeric seal shall be taken at randomfrom each shipment of material. If the shipment consists ofmore than one lot, a sample from each lot shall be taken.8.3 A minimum of 4 linear ft (1.2 m) of elastomeric sealshall constitute one sample for testing purposes.9. Specimens Preparation9.1 Preformed
22、elastomeric seal specimens shall be preparedin accordance with the prescribed methods in SpecificationD2628.10. Test Methods10.1 Determine compliance with the requirements of Table1 by conducting tests on the preformed elastomeric seals inaccordance with the methods specified.11. Certification and A
23、cceptance11.1 The acceptance of the preformed elastomeric seal andsteel rails shall be based upon one of the following proceduresas specified by the purchaser.11.1.1 A certification of conformance to the specificationrequirements. This shall consist of a copy of the producers testreport or a stateme
24、nt by the supplier accompanied by a copy ofthe test results, certifying that the material has been sampled,tested, and inspected in accordance with the provisions of thisspecification. Each certification so furnished shall be signed byan authorized agent of the producer or supplier.11.1.2 A certific
25、ation of test results by an independenttesting agent and a statement that the material has beensampled, tested, and inspected in accordance with the provi-sions of this specification. Each certificate so furnished shall besigned by an authorized agent of the testing agency.11.1.3 Testing by the purc
26、haser of any or all properties inaccordance with the provisions of the specification.11.2 If no procedures are specified, the provisions of 11.1.1shall apply.12. Marking12.1 The seals and steel rails shall be marked with the lotnumber, the name or suitable trademark of the producer, andshall be iden
27、tifiable as to its manufacturer by die markings orother means. These markings shall be in a location visible afterinstallation of the system.12.2 Containers in which the seals and adhesive-lubricantare packaged for shipment shall be clearly marked with thename of the producer, the size of the seal,
