1、Designation: D 3206 08Standard Test Method forSoil Resistance of Floor Polishes1This standard is issued under the fixed designation D 3206; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in pare
2、ntheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers the determination of soil resis-tance of floor polishes on test tile only. A carpet covered rolleris used to simulate the ac
3、tion of foot traffic. A synthetic soil isemployed in conjunction with the roller.1.2 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 and health practices and de

Procedure5.1 Clean the test tile in accordance with Test MethodD 3153, paragraph 9.1.2. Rinse well and allow to dry. Apply 2mL of polish by following Method B of Test Methods D 1436.Aft

Age the tiles for 48h at room temperature.5.2 Sprinkle carefully, as evenly as possible, exactly2gofsoil across that portion of the tile over which the roller willtrack. Run the machine for 300 cycles (600 passes). During thecycling, it may be necessary to occ
9、asionally brush the soil backonto the track as it will be scattered by the motion of the roller.At the end of the test, wipe the surface with tissue to removeany loose soil. Wipe firmly, but do not bear down.NOTE 1Before new carpeting on the roller is used for the first time, itshould be “broken in”
10、 by running over a blank tile with approximately 4g of soil for 500 or more cycles.6. Evaluation of Results6.1 Measure 45-deg, 0-deg directional (diffuse) luminous(green filter) reflectance with instrument of type specified inTest Method E97. Set the clean tile, with two coats of polish,at 100 with

In this case no glossmeter or reflectometer isrequired.8. Precision and Bias8.1 When performed as described, the test method willdifferentiate be
17、tween polishes that resist dirt pick-up well andthose that do not. The test is more accurate when performedwith a control sample whose soil resistance is known. Repli-cate tests show good reproducibility.8.2 Since there is no accepted reference material for deter-mining the soil resistance of polish
18、 films, bias has not beendetermined.9.
