1、Designation:D 1854 02Standard Specification forJet-Fuel-Resistant Concrete Joint Sealer,Hot-AppliedElastic Type1This standard is issued under the fixed designation D 1854;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of la
2、st revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon(e)indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.Scope1.1 This specification covers a jet-fuel-resist
3、ant concretejoint sealer,of the hot-applied elastic type,intended for use insealing joints in concrete pavement in areas exposed to jet fuelspillage.It may be found useful in industrial areas wheresimilar conditions exist(see Appendix X1).1.2 The values stated in SI units are to be regarded asstanda
4、rd.The values in parentheses are for information only.The values stated in each system may not be exact equivalents;therefore,each system shall be used independently of the other.Combining values from the two systems may result in non-conformance to the standard.1.3 This standard does not purport to
5、 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-bility of regulatory limitations prior to use.Specific precautionstatements are given in Appendix X1.
