1、Designation: D 5973 97 (Reapproved 2007)Standard Specification forElastomeric Strip Seals with Steel Locking Edge Rails Usedin Expansion Joint Sealing1This standard is issued under the fixed designation D 5973; the number immediately following the designation indicates the year oforiginal adoption o
2、r, in the case 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 material requirements forpreformed elastomeric
3、strip 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
4、 webs 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 recomm
5、endedthat 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-po
6、und system shall beconsidered as standard.2.

Physical Properties5.1 The elastomeric seals shall conform to the physicalproperties prescribed in Table 1.5.2 The structural st
15、eel locking edge rail shall conform toSpecifications A 588/A 588M,5A 36/A 36M, A 572/A 572M,or as specified by the purchaser.5.3 The adhesive-lubricant shall conform to SpecificationD 4070.6. Dimensions and Tolerances6.1 The size, shape, and dimensional tolerances shall be asagreed upon by the purch
16、aser 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 seals and steelin the area where the seal fits into the steel locking edge rail,with the understan
17、ding 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 the lug that comes in contact with thesteel locking edge rail with a solvent, such as acetone. T
18、hestandard 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 5 % the depth of the cross-sectionalthickness. Talc residue is acceptable except in areas to
19、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 greater than 5 % of the thickness of the steel at theirlocation. The steel cavity in contact with t
20、he 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 elastomeric seal shall be taken at randomfrom each shipment of material. If the shipment consi
21、sts 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 elastomeric seal specimens shall be preparedin accordance with the prescribed methods in Speci
22、ficationD 2628.10. Test Methods10.1 Determine compliance with the requirements of Table1 by conducting tests on the preformed elastomeric seals inaccordance with the methods specified.11.
