1、Designation:D315387(Reapproved 2015)Standard 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 rev
2、ision.A number 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
3、the same 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.NOTE1Recoatability of a water-emulsion floor polish is a general-performa
4、nce 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 of g
6、loss,by recoating.1.3 Adegree 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,associated with
7、 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.Referenced Documents2.1 ASTM Standards:2D2825 Terminology Relating to Polishes and Related Mate-rials3.Termino
8、logy3.1 Definitions of Terms Specific to This Standard:3.1.1 beadingthe apparent failure of the liquid polish towet out the surface as evidenced by the gathering of the polishinto puddle-like beads.3.1.2 dragthe resistance observed when the wet applicatoris moved over the wet coating,when the polish

10、y the applicatorduring the spreading of the liquid polish.3.1.6 whiteningthe development of a white color on orwithin a coating during the drying process,which reduces thefunctioning of a polish to beautify and(possibly)protect floors.4.Summary of Test Method4.1 The test method involves the applicat
11、ion of floor polishusing,but not restricted to,cheesecloth or lambs woolapplicator for spreading a measured amount of polish,overpreviously applied coatings of the polish.The test methodincludes a fast recoat cycle at 30 min which can also be usedfollowing manufacturers directions and an extended re
12、coatcycle of seven days.All tests are run on commercial floor tile.5.Significance and Use5.1 The essential practical usage of water-emulsion floorpolishes as renewable coatings to protect and beautify floors,depends upon satisfactory recoatability.This test method isuseful both in product developmen
13、t and final product testing,as a means of evaluating recoatability.6.Interferences6.1 The presence of the factory finish,mold-release agents,or other foreign materials on the test surface,prior to the firstapplication of the polish that is to be tested in accordance withthis method,will cause irregu
14、lar results.Abrading the surfaceof the test panel or area(for example,by cleaning with anabrasive pad)prior to the first application of the polish,willyield abnormal results.The cleaning formula listed in Footnote3 should be used to remove the above mentioned coatings.1This test method is under the
