1、Designation: D3758 95 (Reapproved 2010)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 and health practices and determine the applica-bility of

Significance and Use4.1 Spray buff products a

8、re utilized for the maintenance ofpolished floors. This practice is for the evaluation of a spraybuff product against a reference product. The procedure is afloor test utilizing a rotary-disc floor machine. This practice ascurrently written may or may not be applicable for machines inexcess of 350 R

Apparatus5.1 Floor Machine of the single-disk type, fitted with a paddriver and a spray-buffing floor maintenance pad.5.2 GlossmeterThe instrument and the reference stan-dards shall conform to the requirements prescribed in TestMethod D523, using an angle of reflection of 60.6. Description o

10、f 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 the corridor. Use one section foreach te

11、st 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.7.2 Coat two test sections of the corridor with base polish.Maintain one test section with the test spr

Wait 1 h after the

16、 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 clean bristle brushattachment 30 min after the third coat is a

17、pparently 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 32C), and above 70 % relative humidity, may necessi-tate longe

18、r 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 test section should be spray buffed twice weekly, or,if traf

19、fic 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 thefloor-cleaning machine. Apply the spray-buff product uni-

20、formly, using as little as possible to achieve cleaning requiredand obtain optimum appearance level. Typical application rateis 0.08 to 0.30 g/ft2(0.86 to 3.23 g/m2). Weigh the spray bottleor aerosol container of spray-buff product before and afterapplication to the test area to determine the amount

21、 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 test area, move forward and repeatapplication and cleaning p

22、rocedure. 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 separate spray-buffing floor maintenancepad with each different sp

23、ray-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 record the time required to clean andpolish each test section a

24、fter 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 buffing, soilingbefore spray buffing, specular gloss at 60 of th

25、e 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-buffingoperation. Perform this operation no later than the end

26、 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 observations such astraffic, soiling, appearance of test floors, etc

27、.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 material+1 slightly better than reference material+2 much better tha

28、n 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, the range between the highest and lowestvalue, will help show t

29、he agreement between observers. Therange between +2 and 2 is 4.9.3 Tabulate the results on an appropriate data sheet.10. Report10.1 Report the average application rate of spray-buff prod-uct, the average time (or number of passes) required forcleaning and polishing the test area with the spray-buffp

30、roduct, and the average relative slip resistance of the test area.10.2 Report the evaluation results as the average of theindividual ratings of the three or more observers, carried to twodecimal places (for example, 1.25).10.3 As an indication of the agreement between observers,report the range betw

31、een the highest and lowest individualobservers evaluation.10.4 Report unusual conditions or observations relevant totraffic, soiling, appearance of test floors, etc.11.
