1、Designation: D3209 93 (Reapproved 2015)Standard Test Method forFreeze/Thaw Resistance of Polymer Floor Polishes1This standard is issued under the fixed designation D3209; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of
2、last revision. A number 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 the stabil-ity of polymer emulsion floor polishes when these are exposedt
3、o repeated cycles of freezing and thawing. Possible degrada-tion of the emulsion is observed and possible reduction ofinitial gloss is measured.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 of this standa
4、rd to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2. Referenced Documents2.1 ASTM Standards:2D1455 Test Method for 60 Specular Gloss of EmulsionFloor Polish3. Significance and Use3.1 This test method is used to determine
5、the effect offreezing on floor polishes. It may be used to predict thestability of a floor polish when exposed to freezing.4. Apparatus4.1 Freezer, adjusted to 7.8 to 6.7C (18 to 20F).4.2 Flint Glass Bottles, three, 4 oz (125 mL) capacity.34.3 Black Glass,4standard, polished as described in TestMeth

Procedure5.1 Determine the turbidity of each polish, visually or byany other suitable method.5.2 Pour one coat of each polish to be tested on the blackglass. Allow to dry in a vertical position at room temperature.Determine the initial gloss i
7、n accordance with Test MethodD1455.5.3 Place 100 mL of polish in each of three 125-mL (4-oz)flint glass bottles. Place the filled bottles side by side,horizontally, in the freezer on a rack, providing a minimum of25 mm (1 in.) between the bottles and the freezer walls with thecontact area between th
8、e bottles and the rack no greater thanthat required to support the bottles.5.4 Allow the samples to remain in the freezer for 16 h, ora minimum of 8 h after becoming solid.5.5 Remove all the samples of frozen polish and allow tothaw, undisturbed, at 18 to 24C (65 to 76F) for a period of 24h.5.6 Insp
9、ect all thawed samples visually. Observe and recordany separation, stratification, or coagulation.5.7 Determine the turbidity on the open sample of polish asin 5.1.5.8 Agitate one bottle of thawed polish and apply one coatof polish to the standard black glass as in 5.2. Determine glossas in 5.2.5.9
10、Return the remaining two bottles of polish to the freezerfor 16 h, and repeat 5.4 5.8 for the second freeze/thaw cycle.1This test method is under the jurisdiction ofASTM Committee D21 on Polishesand is the direct responsibility of Subcommittee D21.03 on Chemical and PhysicalTesting.Current edition a

Interpretation of Results6.1 The polish passes each freeze/thaw cycle if there hasbeen no apparent change in appearance and no significant lossin gloss or increase in turbid
16、ity.7. Report7.1 Report test results as the number of cycles passedtogether with visual inspection comments regarding possibleseparation, stratification, or coagulation.8. Precision and Bias8.1 The test method differentiates polishes that are freezestable from those which are not. Polishes that are
17、borderline infreeze/thaw stability may pass in some laboratories and fail inothers.8.2 BiasSince there is no accepted reference materialsuitable for determining the bias for the procedure in TestMethod D3209 for measuring freeze/thaw resistance of poly-mer emulsion floor polishes, bias has not been
18、determined.9.
