1、Designation:D320608(Reapproved 2015)Standard 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 numbe
2、r in parentheses 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
3、 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 health practices and det

7、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 Method B of Test Methods D1436.After 3
8、 h,apply a second coat,also 2 mL.Age the tiles for 48h at room temperature.5.2 Sprinkle carefully,as evenly as possible,exactly 2 g ofsoil 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
9、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.NOTE1Before new carpeting on the roller is used for the first time,itshould be“broken in”by running over
