1、Designation:D71312(Reapproved 2017)Standard Practice forConducting Road Service Tests on Fluid Traffic MarkingMaterials1This standard is issued under the fixed designation D713;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year
2、 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 practice covers the determination of the relativeservice life of fluid traffic marking materials such as paint,the
3、rmoplastic,epoxy,and polyester products under actual roadconditions using transverse test lines.Materials under test areapplied under prescribed conditions and periodic observationsare made using prescribed performance criteria.1.2 The values stated in SI units are to be regarded as thestandard.The
4、values given in parentheses are for informationonly.1.3 This standard does not purport to 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,health,and environmental practices and deter-mine the appli

10、ight hours,and there is good drainage.Select surfaces thatare representative of the pavements upon which the fluid trafficmarking material will be used in practice.Such surfacesinclude portland cement concrete,sheet asphalt,bituminousconcrete,rock asphalt,and bituminous surface treatment.5.Condition
11、s at Time of Application5.1 Clean the test area thoroughly of all foreign material.Follow the pavement marking manufacturers recommendationfor the application of the pavement marking to be tested.Thisshould include the recommendations for air and pavementtemperature,material temperature,relative hum
12、idity,windchill,and wind speed.Application between 10 a.m.and 3 p.m.is recommended.During application record air and pavementtemperature,wind speed,and relative humidity hourly.6.Measurement of Wet Film Thickness6.1 To aid in obtaining the correct film thickness,a length ofroofing paper placed by th
13、e side of the road can be used.Placea rigid metal test panel on the roofing paper and in the path ofthe test line.A 300 by 300-mm(12 by 12-in.)metal panel 1.5mm(116in.)in thickness is satisfactory.Immediately after thetest line is applied by the motorized striper,read the wet filmthickness.If the we
