Designation:D6754/D6754M15Standard Specification forKetone Ethylene Ester Based Sheet Roofing1This standard is issued under the fixed designation D6754/D6754M;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.1.Scope1.1 This specification covers flexible sheet made fromketone ethylene ester(KEE)as the primary polymer intendedfor use in single ply roofing membrane exposed to the weather.The sheet shall be reinforced with fabric.1.2 In-place roof system design criteria,such as fireresistance,field-seaming strength,material compatibility,upliftresistance,in-situ shrinkage,among others,are factors thatmust be considered,but are beyond the scope of this specifi-cation.1.3 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.1.4 The following precautionary caveat pertains to the testmethods portion only,Section 8,of this specification:Thisstandard does not purport to address all of the safety concerns,if any,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 require-ments prior to use.2.Referenced Documents2.1 ASTM Standards:2D471 Test Method for Rubber PropertyEffect of LiquidsD751 Test Methods for Coated FabricsD1079 Terminology Relating to Roofing and WaterproofingD1204 Test Method for Linear Dimensional Changes ofNonrigid Thermoplastic Sheeting or Film at ElevatedTemperatureD2136 Test Method for Coated FabricsLow-TemperatureBend TestD3045 Practice for Heat Aging of Plastics Without LoadD3389 Test Method for Coated Fabrics Abrasion Resistance(Rotary Platform Abrader)D5602 Test Method for Static Puncture Resistance of Roof-ing Membrane SpecimensD5635 Test Method for Dynamic Puncture Resistance ofRoofing Membrane SpecimensD7635/D7635M Test Method for Measurement of Thicknessof Coatings Over Fabric ReinforcementG21 Practice for Determining Resistance of Synthetic Poly-meric Materials to FungiG151 Practice for Exposing Nonmetallic Materials inAccel-erated Test Devices that Use Laboratory Light SourcesG154 Practice for Operating Fluorescent Ultraviolet(UV)Lamp Apparatus for Exposure of Nonmetallic MaterialsG155 Practice for Operating Xenon Arc Light Apparatus forExposure of Non-Metallic Materials3.Terminology3.1 DefinitionsTerminology D1079 shall apply to thisspecification.3.2 ketone ethylene ester(KEE),na high molecularweight thermoplastic copolymer of ethylene,containing carbonmonoxide and either vinyl acetate or acrylate monomer whichare incorporated to provide softness and polarity.3.2.1 DiscussionEster groups of the vinyl acetate oracrylate are pendant from the ethylene backbone and reducecrystallinity,which provides flexibility.Carbon monoxidegroups within the polymer backbone provide polarity.TheKEE polymer is therefore a flexible polymer,which is misciblewith other polymers of similar polarity.3.3 polymer content,nin this specification,polymer con-tent shall be defined as polymeric materials which are in thesolid state at room temperature,and are high(greater than50 000 Mw)in molecular weight.Other ingredients,known tothe art of polymer compounding,such as certain waxes,stabilizers,and other additives,while polymeric in nature arenot considered to be part of the base polymer system.4.Materials and Manufacture4.1 The sheet shall be formulated from the appropriatepolymers and other compounding ingredients.The KEE poly-mer shall be a minimum of 50%by weight of the polymercontent of the sheet.1This specification is under the jurisdiction of ASTM Committee D08 onRoofing and Waterproofing and is the direct responsibility of Subcommittee D08.18on Nonbituminous Organic Roof Coverings.Current edition approved Nov.1,2015.Published November 2015.Originallyapproved in 2002.Last previous edition approved in 2010 as D6754/D6754M 10.DOI:10.1520/D6754_D6754M15.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.2 The sheet shall be reinforced internally with a fabric.4.3 To make seam and repairs,the sheet shall be capable ofbeing bonded watertight to itself during the design service lifeof the sheets.The manufacturer shall recommend a suitablemethod.Design service life is defined as the designated timeperiod of intended system
