1、Designation:D315317Standard 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 number in
2、 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 same polish.T
3、he 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-performance property,and
4、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 the recoatability
5、 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 gloss,by recoating
6、.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 its use.It is th
7、eresponsibility 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 on standard-ization estab
