1、Designation: D3153 17Standard Test Method forRecoatability of Water-Emulsion Floor Polishes1This standard is issued under the fixed designation D3153; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A num

2、ber 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 effectsof the application of a water-emulsion floor polish over a driedcoating of the sam

3、e polish. The method is designed forlaboratory bench panel testing. A method is also provided forlarge area testing. A rating system is provided to indicate theacceptability of the polish based on recoatability performance.NOTE 1Recoatability of a water-emulsion floor polish is a general-performance

4、 property, and the determination of it is dependent upon theobservation of several other properties of the polish under the specificconditions expressed in this test method. This test method for recoatabilityis not designed for the evaluation of other properties, except as theseproperties relate to

5、the recoatability of the specific polish being evaluatedunder the conditions of this test.1.2 Gloss as observed herein extends only to freedom fromloss of apparent visual gloss upon recoating, in the execution ofthis test method, and should this loss occur, it indicates adistortion of the property o

6、f gloss, by recoating.1.3 A degree of recoatability failure may be reflected from adegree of leveling failure. The failure to level should beobserved only if it is to be a part of the observation ofrecoatability.1.4 This standard does not purport to address all of thesafety concerns, if any, associa

7、ted 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.1.5 This international standard was developed in accor-dance with internationally recognized principles

Procedure9.1 Bench Panel Test:9.1.1 Selection of PanelsSelect either five black vinyl(homogeneous) floor tile panels or five black vinyl compositionfloor tile panels, for ea

23、ch polish under test, basing selection onlike-new condition. Do not intermix these two types of testsurfaces in any one test sequence.9.1.2 Preparation of Test PanelsPrepare five panels foreach polish under test by cleaning with undiluted comparisoncleaning solution described in Footnote 6.6Soak the

24、 panelsface to face for 20 min. Using a soft brush or clean cheesecloth,scrub thoroughly to remove all coatings, soil, etc. Rinsethoroughly with clear water and let dry completely.9.1.3 Application of PolishPrepare a swab 50.8 mm (2 in.)square and twelve plies thick, using clean cheesecloth, free of

25、sizing. Immerse the swab in the test polish and squeeze out theexcess. Pipet 2.6 ml (Note 3) of the test polish on to the surfaceof a test panel, which should be lying level on a horizontalsurface, and spread the polish uniformly, using the swabpreviously prepared. Repeat for the other four panels.

26、Observethe coatings on all five panels after they have dried for 30 min.or following manufacturers directions, under average ambientconditions. Note the similarity. If the appearance of the coatingon all panels is not uniformly equal, discard these panels, andprepare a new group of coated panels usi

27、ng the aboveprocedure.NOTE 32.5 mL of polish are used for 12 by 12-in. (304.8 by304.8-mm) panels. 1.4 mL of polish are used for 9 by 9-in. (228.6 by228.6-mm) panels. Test can be performed using polish manufacturersrecommended rate of application.9.1.4 Application of Second CoatThirty minutes afterap

28、plication of the first coat of polish, or following manufac-turers dry time recommendations, take two of the five panelsand apply on each a second coat using the procedure detailedin 9.1.3 for applying and spreading the polish. Record thetemperature and relative humidity. Observe and record anyfoami

29、ng of the polish and drag of the applicator duringapplication and spreading. Observe and record any beading ofthe polish or required additional stroking with applicator to wetout the surface. Allow to dry 2 h, and observe and record anyremoval of the first coat, any whitening, streaking, or ghosting

30、.Observe and record leveling. Visually observe the apparentgloss of the recoated polish, and record the comparison withthe single coat of polish.9.1.5 After allowing them to remain undisturbed for sevendays under average ambient conditions, take two of the threeremaining panels which have a single c

42、licate tests may be conducted ifthe results are in doubt.10. Calculation and Interpretation of Results10.1 Since a number of floor polish properties collectivelydetermine the property of recoatability, the evaluation ofrecoatability must be confined to the general appearance of themulticoat finish i

43、n relation to the single coat finish. Rate themulticoat finishes as follows:10.1.1 Goodappearance of the multicoat finish signifi-cantly superior to the single-coat finish.10.1.2 Fairappearance of the multicoat finish only mar-ginally superior or inferior to the single-coat finish.10.1.3 Poorappeara

44、nce of the multicoat finish signifi-cantly inferior to the single-coat finish.11.
