1、Designation: D 1436 97 (Reapproved 2008)Standard Test Methods forApplication of Emulsion Floor Polishes to Substrates forTesting Purposes1This standard is issued under the fixed designation D 1436; the number immediately following the designation indicates the year oforiginal adoption or, in the cas
2、e of revision, the year 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 These test methods cover procedures for application ofemulsion floor polish films to suita
3、ble substrates for testingpurposes. Five test methods are covered, as outlined in Section3.1.2 These procedures are limited to use on flat, rigidsubstrates mounted, if necessary, on a nonabsorbent backing.1.3 The values stated in SI units are to be regarded as thestandard. The values given in parent
4、heses are provided forinformation only.1.4 This standard does not purport 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 l
5、imitations prior to use.2. Significance and Use2.1 All five of the test methods described will producepolish films from emulsion floor polishes which can be used forvarious performance tests. The choice of test method is left upto the individual laboratory.3. Choice of Test Method3.1 Under actual us
6、e conditions, the thickness of the driedfilm deposited from water emulsion floor polishes ranges from0.03 mil to 0.4 mil. No one laboratory method has been foundthat will produce uniformly thick films throughout this rangeon all substrates. In many cases, the surface roughness andporosity of the sub
7、strate is of the same order of magnitude asthe thickness of the deposited films. Therefore, several alter-native methods have been developed. Unless otherwise speci-fied, the choice of method of application and substrate shall bemutually agreed upon by the purchaser and the seller. Thecharacteristic
8、s of the five methods are as follows:3.1.1 Method A. Automatic Dip CoaterThis method pro-duces thin films of excellent uniformity on the first coat withsubstrates of low or moderate porosity. Two- or three-coatapplications may produce partial solubility of the earlier coatswith consequent loss of un
9、iformity.3.1.2 Method B. Hand ApplicatorThis method simulatesuse conditions and produces thin films of satisfactory unifor-mity for many test purposes where the area of the test panel issmall (304.8 by 304.8 mm (12 by 12 in.) or smaller). With largepanels, considerable local nonuniformity of film th
10、ickness mayresult.3.1.3 Method C. Manual Dip MethodThis method resultsin wedge-shaped films, of moderate thickness, that are thickerat the bottom than at the top of the panel. This method is rapidand results in reproducible films in the center of the test panelwhich are useful for comparison tests a
11、nd for tests involvingthe surface properties of the wax film.3.1.4 Method D. Blade ApplicatorThis method merelyspreads a known volume of emulsion over a known surfacearea. The uniformity of the resulting film depends on theflatness of the substrate, the surface tension of the emulsion,and the interf
12、acial tension between the emulsion and thesubstrate. The method is satisfactory for producing thick tomoderately thin films. Some practice and familiarity with themethod are necessary to produce uniform thin films.3.1.5 Method E. Pour SurfaceThis method covers pour-ing a small amount of polish over
13、a tile held at a 45 angle andallowing it to flow uniformly down the tile and coating it.Afterthe polish is poured and the bottom bead forms, it is wiped offand allowed to dry. The method is satisfactory for producingthick films for slip resistance testing.4. Standard Conditions4.1 The materials and
14、apparatus shall be permitted to cometo equilibrium in an atmosphere having a relative humidity of50 6 4 % and a temperature of 23.8 6 1.1C (75 6 2F).1These test methods are under the jurisdiction of ASTM Committee D21 onPolishes and are the direct responsibility of Subcommittee D21.04 on Performance

16、sion floor polish shall becarried out under the conditions specified in 4.1.TEST METHOD A. APPLICATION OF EMULSIONFLOOR POLISH BY THE AUTOMATIC DIP COATER5. Apparatus5.1 Automatic Dip CoaterThe automatic dip coater shallconsist of a mechanism that will withdraw a panel from a tankof the emulsion at
17、a predetermined rate. A suitable apparatus2consists of a constant-speed motor to which a pulley isattached. The diameter of the pulley is such that the cord andhook assembly attached to it will have a speed of 101.6 mm (4in.)/min. The speed of withdrawal is kept uniform and is lowerthan that at whic
18、h the coating drains. The test substrate must bewithdrawn from the test solution entirely free of vibration.5.2 Dip Tank, any tank with cover suitable for immersion ofthe substrate into the emulsion. The substrate must not touchthe sides of the tank during withdrawal.6. Procedure6.1 Place the test s
19、ubstrate on the hook and lower itsufficiently into the dip tank to coat the panel to the desiredarea, using the cord. Place the other end of the cord around thepulley and give it one complete turn about the pulley. Attachthe counterbalance and start the motor.6.2 Following withdrawal from the emulsi
20、on, suspend thesubstrate on the hook or place it in a vertical position for 24 hunder standard conditions.TEST METHOD B. APPLICATION OF EMULSIONFLOOR POLISH WITH A HAND APPLICATOR7. Apparatus7.1 Balance, capacity 50 g, with an accuracy of 60.05 g.7.2 Pipet, Mohr, 5-mL, graduated in 0.1-mL divisions.
21、7.3 Applicator, consisting of absorbent soft cheeseclothwashed to remove sizing, cut into 51-mm (2-in.) strips offour-ply cloth, trimmed to weigh 0.60 g, and folded twice.8. Procedure8.1 1.8 mils of polish on a 12 by 12 in. OVCT will usuallyequate to an approximate rate of 2100 ft2/gal.8.2 Pipet the
22、 required amount of emulsion onto the center ofthe test panel. Place a cheesecloth strip over the solution andallow it to absorb the emulsion. Distribute the emulsion evenlyover the surface; then draw the cheesecloth downward once inseparate strokes until the entire panel is crossed with no morepres
23、sure than is exerted by the weight of the hand. Immediatelyplace the used cheesecloth in a ground-glass stoppered, taredweighing bottle, weigh, and calculate and record the net weightof the used wet applicator.8.3 To ensure a constant film thickness, the weight of thespent applicators should not var
24、y by more than 0.15 g. If theweight variation exceeds 0.15 g, the test panel should bediscarded.8.4 Dry the coated substrates for 18 to 24 h under standard-conditions before testing.9. Calculation9.1 Assuming 1 mL of the emulsion as equal to 1 g,calculate the weight of emulsion applied to the test p
25、anel asfollows:Weight of emulsion on test panel, g 5 A 1 0.60! 2 B (1)where:A = total weight of emulsion applied on applicator and testpanel, g, andB = weight of used wet applicator, g.TEST METHOD C. APPLICATION OF EMULSIONFLOOR POLISH FILMS BY MANUAL DIP10. Apparatus10.1 Dip Tank, any tank with cov
26、er suitable for immersionof the substrate into the emulsion.11. Procedure11.1 Immerse the substrate completely into the dip tankcontaining the emulsion to be tested for 1 min. Then withdrawthe substrate as quickly as possible without touching the sidesof the vessel, and place in a vertical position
27、and allow to dryunder standard conditions for 24 h.11.2 If a two-coat application is required, reverse thesubstrate in drain drying so as to equalize the film thickness.TEST METHOD D.

APPLICATION OF EMULSIONFLOOR POLISH BY POUR SURFACE14. Procedure14.1 Pour a small quantity (10 to 15 mL) of polish over t
32、hesubstrate which is held at a 45 angle. After pouring the polishon the surface and it is uniformly distributed, wipe off the beadformed at the bottom and allow to dry.14.2 Allow the resultant film to dry 24 h under standardconditions.15. Precision and Bias15.1 Each test method will produce replicat
33、e films from apolish sample. The same application method should be usedthroughout a test series in order to obtain film uniformity.15.2 Since there is no accepted reference material suitablefor this test method for measuring the application of emulsionfloor polishes to substrates for testing purpose
