1、Designation: D 5678 95 (Reapproved 2008)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 topredict
6、 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(OVCT),3

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 side,
9、 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 all t
10、he 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. Then app
11、ly 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 and reco
