1、Designation: D 5678 95 (Reapproved 2002)Standard Test Method forFreeze/Thaw Resistance of Wax Emulsion Floor Polish1This standard is issued under the fixed designation D 5678; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the yea
2、r of last revision. 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 the stabil-ity of wax emulsion floor polishes when these are expose
3、d torepeated cycles of freezing and thawing. Possible degradationof the emulsion is observed and possible reduction of initialgloss is measured.1.2 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonly.1.3 This standard does not purp
4、ort 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 determine the applica-bility of regulatory limitations prior to use.2.

Significance and Use3.1 This test method is used to determine the effect offreezing on wax emulsion floor polishes. It may be used top
6、redict the stability of a floor polish in transit or when exposedto freezing, and whether or not the polish is damaged byfreezing.4. Apparatus4.1 Freezer, adjusted to 7.8 to 6.7C (18 to 20F).4.2 Clear Bottles, three, 4 oz (125 mL) capacity.4.3 Test Flooring SubstratesOffcial Vinyl Composition Tile(O
7、VCT),3black, 304.8 mm (12 by 12 in.).4.4 60-Deg Gloss Meter.4.5 Polishes, to be tested.5. Procedure5.1 Determine the turbidity of each polish, visually or byany other suitable method.5.2 Apply one coat of each test polish on a black vinylcomposition tile using pour method (E) (see Test MethodD 1436)
8、. Allow polish to dry in a vertical position at roomtemperature. After polish is dry, wait 1 h, then buff with a softcotton cloth. Determine the initial gloss in accordance withTest Method D 1455.5.3 Place 100 mL of polish in each of three 125 mL (4 oz)clear bottles. Place the filled bottles side by
9、 side, horizontally,in the freezer on a rack. Provide a minimum of 25 mm (1 in.)between the bottles and the freezer walls and keep the contactarea between the bottles and the rack to a minimum.5.4 Allow the samples to remain in the freezer for 16 h, ora minimum of 8 h after becoming solid.5.5 Remove
10、 all the samples of frozen polish and allow tothaw, undisturbed, at 18 to 24C (65 to 76F) for a period of 24h.5.6 Inspect all thawed samples visually. Observe and recordany separation or stratification without disturbing the sample.5.7 Mix one bottle of the thawed polish by inverting it tentimes. Th
11、en apply one coat of polish on a black vinylcomposition tile using the same procedure as in 5.2. Allowpolish to dry in a vertical position at room temperature. Afterpolish is dry, wait 1 h, then buff with a soft cotton cloth.Determine the gloss in accordance with Test Method D 1455.Also determine an
12、d record while applying the polish if thisagitated sample is a free flowing liquid, or has separated, or haslarge particles that cannot be buffed.5.8 Determine the turbidity on the open sample of polish asin 5.1.5.9 Return the remaining two bottles of polish to the freezerfor 16 h, and repeat 5.4-5.
13、8 for the second freeze/thaw cycle.5.10 Return the third bottle of polish to the freezer for 16 hand again repeat 5.4-5.8.6. Interpretation of Results6.1 The polish passes each freeze/thaw cycle after mixing ifthere has been no meaningful change in appearance, forexample, separation, large particles

Polishes that areborderline in freeze/thaw stability may pass in some laborato-ries and fail in others.8.2 BiasThis test method has n
