1、Designation: D3758 95 (Reapproved 2017)Standard Practice forEvaluation of Spray-Buff Products on Test Floors1This standard is issued under the fixed designation D3758; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of las

2、t revision. 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 comparison of the performanceof spray-buff products on test floors against a referencematerial.

3、Spray-buff products are to be used to maintain basefloor-polish films. This technique is intended to be used onwater-emulsion floor polishes with a floor machine not exceed-ing 95 lb (43 kg) in weight and with a rate of rotation of 350rpm or less.1.2 Gloss, heel marking, soil resistance, and slip re

4、sistanceof the spray-buffed test panels are rated in comparison to testpanels similarly maintained with a reference spray-buff prod-uct.1.3 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided f

5、or information onlyand are not considered standard.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, health, and environmental practices and deter-mine the a

6、pplicability of regulatory limitations prior to use.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recom-mendations issued

Description of Test Area6.1 The preferred area is a corridor in normal traffic serviceexposed to nearly uniform traffic over the test area.6.2 The preferred substrate is vinyl tile.6.3 Divide the area into test sections at least 4 ft (1.2 m) inlength and the full width of t

12、he corridor. Use one section foreach test material in addition to the control section.7. Preparation of Test Area7.1 Completely strip the test area of dirt and old floor polish.Thoroughly rinse and dry before applying the base polishes.1This practice is under the jurisdiction of ASTM Committee D21 o

17、ion with the test spray-buff product andthe other section (control) with a reference spray-buff product.7.2.1 Apply the base polish to the test section, using anysuitable and controlled procedure in accordance with themanufacturers recommendations.7.2.2 Wait 1 h after the first coat has dried to tou

18、ch beforethe application of a second coat. Wait 1 h after the second coathas dried to touch before the application of a third coat ofpolish.7.3 In the instance of wax-emulsion polishes, machine buffthe test section coated with the test wax and the referencematerials with a new 00 steel wool pad or c

19、lean bristle brushattachment 30 min after the third coat is apparently dry. Allother water emulsion polish types considered in this method donot receive any initial buffing.7.4 Allow each test section to dry 1 h before exposing totraffic. Environmental conditions outside the norms, 70 to 90F(21 to 3

20、2C), and above 70 % relative humidity, may necessi-tate longer periods of drying. Make gloss readings on the fourcenter tiles prior to exposure to traffic. (See Test MethodD1455.)8. Maintenance and Evaluation Schedule8.1 Daily maintenance should include dust mopping, drybrushing, or sweeping.8.2 The

21、 test section should be spray buffed twice weekly, or,if traffic and soiling conditions are heavy, three to five timesweekly.8.2.1 Before spray buffing, use a dust mop or floor brush toremove loose dirt and debris. Apply the spray-buff productwith a spray bottle or aerosol to the floor just ahead of

22、 thefloor-cleaning machine. Apply the spray-buff productuniformly, using as little as possible to achieve cleaningrequired and obtain optimum appearance level. Typical appli-cation rate is 0.08 to 0.30 g/ft2(0.86 to 3.23 g/m2). Weigh thespray bottle or aerosol container of spray-buff product beforea

23、nd after application to the test area to determine the amount ofspray-buff product used.8.2.2 Using a side-to-side movement to pass over a portionof the floor, clean and buff the test area with the floor machine.Use two passes to clean and one or two passes to buff. Afterfinishing one portion of the

24、 test area, move forward and repeatapplication and cleaning procedure. Do not let the machine restin one place too long while cleaning. Typical rate of cleaningis 25 to 33 ft2/min (2.32 to 3.07 m2/min), using a 17-in.(432-mm) diameter rotary-disk floor machine. Dust mop orbrush the area. Use a separ

25、ate spray-buffing floor maintenancepad with each different spray-buff product. Continue to use thesame pad with the same spray-buff product. Clean maintenancepads as required. Determine and record application rate for thefirst, fifth, tenth, and fifteenth spray-buffing operation.8.2.3 Measure and re

26、cord the time required to clean andpolish each test section after each cleaning. Report an averagefor each cycle of five cleanings, after the fifth, tenth, andfifteenth spray-buffing operation.8.3 Evaluate the test sections for visual gloss after spraybuffing, heel marking before and after spray buf

27、fing, soilingbefore spray buffing, specular gloss at 60 of the four centertiles in each test area after spray buffing in accordance withTest Method D1455, and for slip resistance after spray buffingin accordance with CSMA Bulletin No. 245-70.8.3.1 Perform the first evaluation after the first spray-b

28、uffingoperation. Perform this operation no later than the end of thefirst traffic week.8.3.2 Subsequent evaluations should occur after the fifth,tenth, and fifteenth spray-buffing operations.8.4 Determine slip resistance on tiles that have been mosttrafficked.8.5 Report unusual conditions or observa

29、tions such astraffic, soiling, appearance of test floors, etc.9. Rating System9.1 The evaluation of the test panels should be made by atleast three qualified observers. Assigning a value of 0 to thereference material, rate each characteristic of the test polish asfollows:0 equal to reference materia

30、l+1 slightly better than reference material+2 much better than reference material1 slightly poorer than reference material2 much poorer than reference material9.2 Report the results as the average of the three or moreobservers carried to two decimal places (for example, 1.25).Anadditional figure, th

31、e range between the highest and lowestvalue, will help show the agreement between observers. Therange between +2 and 2 is 4.9.3 Tabulate the results on an appropriate data sheet.10.
