1、Designation:D3751/D3751M10Standard Practice forEvaluation of Furniture Polish1This standard is issued under the fixed designation D3751/D3751M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in pare
2、ntheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice covers the definition of properties to testand the apparatus to use in evaluating the performance offurniture polishes.1.2 The values state
3、d in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 This st
4、andard 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 limitations prior to use.2.Terminology2.1 Definitions:
5、2.1.1 furniture polisha polish used for cleaning and im-proving the appearance of furniture finishes.3.Significance and Use3.1 This practice defines the properties to be tested,theapparatus to be used,and the comparisons of product perfor-mance.It is recognized that considerable discretion existsamo
6、ng formulators and marketers of furniture polish on whichproperties or performance characteristics are best for theirproducts.This practice will be flexible to honor this fact withinthe confines of the furniture polish definition below.3.2 The methods of testing are subjective and empirical inorder
7、to conform to the basic characteristics of the industry andto allow flexibility in testing.4.Apparatus and Materials4.1 Control Polish,selected subjectively for comparison tothe test polish.It may be a competitive product,a modifiedformulation of the test polish,etc.The one stipulation is thatthe co
8、ntrol polish be of the same or similar type as the testpolish.For example,if the test polish is an aerosol emulsionpolish,the control shall be an aerosol emulsion polish.It wouldnot be meaningful to select a paste or liquid product as acontrol for comparison to an aerosol emulsion test polish.4.2 Te
9、st Substrate for which the test polish is intended.Thetest surface shall be in good physical condition,not badlycracked,scratched,or otherwise damaged so as to interferewith evaluation of polish properties.The minimum test surfacearea for each sample shall be 1290 cm2200 in.2.4.3 Polishing ClothMate
10、rials such as washed cheesecloth,rumple cloth,flannel,cotton diaper cloth,and nonwovenfabrics are suitable for this purpose.The same type polishingcloth should be used with each sample tested.Use separatecloths for each sample.Do not use felt or paper.4.4 Cleaning Solvent,aliphatic,with kauri-butano
11、l valuesless than 38.4.5 Eye Droppers and Tap Water.5.Test Specimen5.1 The test specimen shall be the sample of polish to betested.6.Selection of Testers6.1 The application and evaluation of the test and controlpolishes requires four individuals.They shall be capable ofmaking discriminating judgment
12、s of subjective,physical,andaesthetic properties.Training and orientation to specific prod-uct performance characteristics may be required.6.2 Each person applies the polishes to one of the four testpanels.The tester then rates all properties except applicationproperties on the remaining three panel
13、s that they did notpolish.The person applying the polishes rates ease of use andother application properties.This means there will be only fourreadings on application properties.The three rating the otherpolish properties do not observe the application because theyrate properties of each polish“blin
