1、Designation: D 913 03e1Standard Test Method forEvaluating Degree of Resistance to Wear of Traffic Paint1This standard is issued under the fixed designation D 913; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last rev

2、ision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.e1NOTEAdjunct references were corrected editorially in April 2006.1. Scope1.1 This test method covers the evaluation of degree ofresistan

3、ce to wear that may occur with traffic paints in roadtests (see Practice D 713) or in actual service, using photo-graphic standards for comparative evaluation.1.2 This standard does not purport to address all of thesafety problems, if any, associated with its use. It is theresponsibility of the user

4、 of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

5、 of Photographic Reference Standards33. Description of Term Specific to This Standard3.1 failure, described by these reference standardsthatcondition manifested in traffic paint by actual detachment ofentire sections of the film from its substrate or from paintpreviously applied. The degree of resis

6、tance to failure is judgedby the amount of substrate that is covered.4. Significance and Use4.1 This test method is designed to evaluate the resistance towear of a traffic paint. It must be remembered that a highdegree of performance of paint applied to a bare road surfacemay not guarantee similar r

7、esults when the same paint isapplied over old paint lines.5. Type of Failure5.1 The failure as described in Section 3 does not presumeany specific mechanism, and all areas where the substrate isvisible shall be considered a failure.6. Use of Photographic Reference Standards6.1 The photographic refer

8、ence standards3that are part ofthis test method are representative of the degrees of resistanceto wear of stripes of traffic paint. The examples shown in Fig.1 are for illustration purposes only and should not be used forevaluation.6.1.1 The degree of resistance to wear is likely to vary overany giv

9、en area. It is therefore necessary to use one of thefollowing grading methods:6.1.1.1 Select an area as representative and base the ratingof the stripe on this area or6.1.1.2 Grade segments of the stripe and average thesegradings.6.1.2 The photographic reference standards (Note 1) repre-sent four de

10、grees (97 %, 92 %, 77 %, 60 %) of resistance towear. Substrate revealed by failure is readily discernible withthe naked eye.NOTE 1The reference standards are representative of stripes of trafficpaints. The percentage of surface covered is shown on each referencestandard.7. Procedure7.1 Compare the r
