Standard Test Method for
Freeze/Thaw Resistance of Polymer Floor Polishes1

This standard is issued under the fixed designation D 3209; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 This test method covers the determination of the stability of polymer emulsion floor polishes when these are exposed
to repeated cycles of freezing and thawing. Possible degradation of the emulsion is observed and possible reduction of
initial gloss is measured.

1.2 This standard does not purport to address all of the
safety problems, if any, associated with its use. It is the
responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

2. Referenced Documents

2.1 ASTM Standards:
D 1455 Test Method for 60-Deg Specular Gloss of Emulsion Floor Polish2
3. Significance and Use

3.1 This test method is used to determine the effect of
freezing on floor polishes. It may be used to predict the
stability of a floor polish when exposed to freezing.

4. Apparatus

4.1 Freezer, adjusted to −7.8 to −6.7°C (18 to 20°F).

4.2 Flint Glass Bottles, three, 4 oz (125 mL) capacity.3

4.3 Black Glass, 4 standard, polished as described in Test
Method D 1455.

4.4 60° Gloss Meter.

4.5 Polishes to be tested.

5. Procedure

5.1 Determine the turbidity of each polish, visually or by
any other suitable method.

5.2 Pour one coat of each polish to be tested on the black
glass. Allow to dry in a vertical position at room temperature.
Determine the initial gloss in accordance with Test Method
D 1455
