1、Designation: D3206 17Standard Test Method forSoil Resistance of Floor Polishes1This standard is issued under the fixed designation D3206; 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 parent
2、heses indicates the year of last reapproval. Asuperscript epsilon () 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 actio
3、n 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 deter
4、mine the applica-bility of regulatory limitations prior to use.1.3 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recom-mendati

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 Offcial 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 Standard Soiling CompoundA soiling compound,such as AATCC (American Association of Textile Colorist andChem
8、ist) synthetic soil formula.64.6 Reflectometer, equipped with a search unit for measur-ing diffused reflectance and a green filter.4.7 Pipet, 2 mL.5. Procedure5.1 Clean the test tile in accordance with Test MethodD3153, paragraph 9.1.2. Rinse well and allow to dry. Apply 2mL of polish by following M
9、ethod B of Test Methods D1436.After 3 h, apply a second coat, also 2 mL. 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 thecy
10、cling, 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 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 fi
11、rst time, itshould be “broken in” by running over a blank tile with approximately 4g of soil for 500 or more cycles.1This test method is under the jurisdiction ofASTM Committee D21 on Polishesand is the direct responsibility of Subcommittee D21.04 on Performance TestsCurrent edition approved March 1

United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decisio
16、n on Principles for theDevelopment of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.16. Evaluation of Results6.1 Measure 45-deg, 0-deg directional (diffuse) luminous(green filter) reflectance with instrument of
17、type specified inTest Method E97. 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 quantitative degree of soiling as follows:P 5 100 2 A (1)where:P = percentage of soiling, andA = averag
18、e 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 isrequired.8. Precision and Bias8.1 When performed as described, the test method willdifferentiate be
19、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
20、 films, bias has not beendetermined.9.
