1、Designation:D433094(Reapproved 2017)Standard Practice forEvaluation of Fiberglass Boat Polish and Wax1This standard is issued under the fixed designation D4330;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision
2、.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 practice covers the properties to test and theapparatus to use when evaluating the performance of boatpolishes and waxes,in terms o
3、f ease of application,cleaningefficiency,gloss and improvement of aesthetic appearance.1.2 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
4、 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.Significance and Use3.1 Boat polish or wax aids in cleaning and maintaining thesurface of fiberglass boats.The function of cle
5、aning is veryimportant.3.2 This practice defines the properties to be tested,theapparatus to use,and the comparisons of product performance.It is recognized that considerable discretion exists amongformulators and marketers of boat polish on what properties orperformance characteristics are best for
6、 their products.Thispractice is flexible to honor this fact.3.3 The methods of testing are subjective and empirical inorder to conform to the basic characteristics of the industry andto allow flexibility in testing.Although test panels may be usedfor screening purposes,actual boat surfaces should be
7、 used forthe final evaluation.4.Apparatus and Materials4.1 Sample of Polish or Wax.4.2 Sample of Control Polish or WaxThe control isselected subjectively for comparison to the test sample.It maybe a competitive product,a modified formulation of the testpolish or wax,and so forth.The control must be
8、of the same orsimilar type as the test sample.It would not be meaningful toselect a paste product as a control for comparison to a liquidtest polish or wax.In addition,polishes to be evaluated shouldbe for the same intended use.Products for below the water linemay be different than those designed fo
9、r above the water line.4.3 Test SubstratesThe test substrate3shall be intended forthe test polish or wax.The test surface shall be in good physicalcondition,not badly cracked,scratched,or otherwise damagedso as to interfere with evaluations of polish or wax properties.The minimum test surface area f
10、or each sample shall be 200in.2(1290 cm2).Whenever possible,the evaluation of testpolish or wax should be made on boats subject to actual useand exposure to diverse but normal conditions.4.4 Polishing ClothThe same type of polishing cloth shallbe used with each sample tested.Separate cloths shall be
11、 usedfor each sample.Materials such as washed cheese cloth,rumple cloth,flannel,cotton diaper cloth,and nonwovenfabrics are suitable for this purpose.Felt or paper shall not beused.4.5 Cleaning SolventAliphatic solvents with Kauri Buta-nol values less than 38.4.6 Eye Droppers and Distilled or Deioni
12、zed Water.4.7 Masking Tape,with a38-in.(9.5 mm)width.4.8 Thermometer.4.9 Humidity Gage.5.Test Conditions5.1 The temperature and relative humidity of the test runsshall be measured and recorded.The temperature shall bewithin 55 to 85F(13 to 29C)with a relative humidity of 20to 80%.5.2 The substrate s
