Designation:D3468/D3468M99(Reapproved 2013)1Standard Specification forLiquid-Applied Neoprene and ChlorosulfonatedPolyethylene Used in Roofing and Waterproofing1This standard is issued under the fixed designation D3468/D3468M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1NOTEUnits information was editorially corrected in July 2013.1.Scope1.1 This specification covers liquid-applied neoprene andchlorosulfonated polyethylene synthetic rubber solutions suit-able for use in roofing and waterproofing.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 The following precautionary caveat pertains only to thetest method portion,Section 9,of this specification:Thisstandard does not purport to address the safety concerns,ifany,associated with its use.It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.Referenced Documents2.1 ASTM Standards:2D412 Test Methods for Vulcanized Rubber and Thermoplas-tic ElastomersTensionD429 Test Methods for Rubber
