1、Designation: D 3206 92 (Reapproved 2002)Standard 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
2、. A number in parentheses 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
3、to simulate the action 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 healt

Significance and Use3.1 This test method measures the ability of a floor polish toresist soiling by a standard soil that approximates dirt carried infrom the outside.4. Apparatus4.1 Of
6、fcial Vinyl Composition Tile (OVCT)4white, 304.8by 304.8 mm (12 by 12 in.).4.2 Washability ApparatusThe Gardner straight linewashability machine.4.3 Roller.44.4 Carpeting.54.5 Soil.64.6 Reflectometer, equipped with a search unit for measur-ing diffused reflectance and a green filter.4.7 Pipet, 2 mL.
7、5. 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.After 3 h, apply a second coat, also 2 mL. Age the tiles for 48h at room temperature.5.2 Sprinkle carefully, as eve
8、nly 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 occasionally brush the soil backonto the track as it will be scattered by the motion of the roller.At the end of th
9、e 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” by running over a blank tile with approximately 4g of soil for 500 or more cycles.6. Evaluation of Results6.1 M
10、easure 45-deg, 0-deg directional (diffuse) luminous(green filter) reflectance with instrument of type specified inTest Method E 97. Set the clean tile, with two coats of polish,at 100 with the green filter. After the test, take five readings andaverage.7. Calculation and Report7.1 Calculate the quan
11、titative degree of soiling as follows:P 5 100 2 A (1)where:P = percentage of soiling, andA = average of five readings.7.2 Results may also be reported in a comparative mannerby both examining the soiled test polish and rating it versus astandard polish. In this case no glossmeter or reflectometer is
12、required.1This test method is under the jurisdiction of ASTM Committee D21 on Polishesand is the direct responsibility of Subcommittee D21.04 on Performance Tests.Current edition approved Aug. 15, 1992.

Precision and Bias8.1 When performed as described, the test method willdifferentiate between polishes that resist dirt pick-up well andthose that do not. The test is more accurate when performedwith a
17、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 films, bias has not beendetermined.9.
