Materials and Manufacture6.1 The color, finish and wearing surface characteristicsshall match the sample mutually agreed upon between thebuyer and seller.NOTE 1The colors and patterns that are available are indicated inindividual manufacturers current catalogs. As manufac
17、tured, and due tothe uncontrollable characteristics of the raw material, colors may varysomewhat in hue or shade from the catalog.NOTE 2Differences in color and texture can result in shading variationfrom piece to piece. Color and texture differences or striation is inherentin the manufacturing proc
18、ess and is not considered a defect.NOTE 3Where color match is a concern, samples from the manufac-turer shall be obtained to verify color or shade acceptability, or both.6.2 Bonded rubber crumb flooring shall be of uniformstructure and composition throughout, consisting of rubbergranules thoroughly
19、and uniformly bonded together.7. Performance Requirements7.1 Abrasion ResistanceTest in accordance with TestMethod D3389 method B and with the abrader equipped withH-18 wheels and a load of 500 g. The flooring shall not losemore than 1 g after 1000 cycles.7.2 Flexibility:7.2.1 Material measuring 0.2
20、5 in. (6.35 mm) or thinnerTest in accordance with Test Method F137, both face-in andface-out, using a 0.25 in. (6.35 mm) mandrel. The flooringshall show no tears, flakes, or splitting of the product matrix.7.2.2 Material measuring more than 0.25 in. (6.35 mm)Test in accordance with Test Method F137,
21、 both face-in andface-out, using a mandrel of the same diameter as the materialthickness. The flooring shall show no tears, flakes or splittingof the product matrix.7.3 Static Load LimitTest in accordance with Test MethodF970, with an applied load of 250 lb (113.4 kg).7.3.1 Bonded rubber crumb floor
22、ing shall have a residualindentation of not more than 0.005 in. (0.127 mm).NOTE 4Test Method F970 is suitable only for tiles up to 1 in. thick.7.4 Dimensional StabilityTest in accordance with TestMethod F2199.7.4.1 Bonded rubber crumb flooring shall not change inlinear dimensions more than nominal 0
23、.050 in. per linear foot(60.40 %).NOTE 5Test Method F2199 is suitable only for tiles up to 1 in. thick.7.5 Resistance to HeatWhen tested in accordance withTest Method F1514, the flooring shall have an average Eofnot more than 8.00.7.6 Resistance to Short-Term Chemical ExposureTest inaccordance with
24、Test Method F925 using the followingchemicals, which represent an abbreviated list:White vinegar (5 % acetic acid)Rubbing alcohol (70 % isopropyl alcohol)Sodium hydroxide solution (5 % NaOH)Hydrochloric acid solution (5 % HCl)Sulfuric acid solution (5 % H2SO4)Household ammonia solution (5 % NH4OH)Di
25、sinfectant cleaner (5 % active phenol)The flooring shall have no more than a slight change in surfacedulling, surface attack or color change.NOTE 6These basic chemicals are representative of those likely to befound in domestic, commercial and institutional use. Many proprietarycompounds contain one
26、or more of these basic chemicals. Should theflooring need to be resistant to a specific chemical, this additionalrequirement should become part of the procurement document.8. Dimensions and Permissible Variations8.1 Type 1 material, roll:8.1.1 ThicknessThe thickness of the floor covering shallbe as
27、specified in the contract or order. The minimum thicknessshall be 0.060 in. (1.5 mm). A tolerance of 60.020 in. (60.50mm) from the specified thickness shall be permitted, providedthe product thickness does not go below the minimum thick-ness of 0.060 in. (1.5 mm). Thickness is measured in accor-danc
28、e with Test Method F386.8.1.2 Length and WidthThe length/width shall not be lessthan as marked on the label, package or as specified in thecontract or order.8.2 Type II material, tile:8.2.1 ThicknessThe thickness of the bonded rubber crumbfloor covering tile shall be as specified in the contract or
29、order.The minimum thickness shall be 0.060 in. (1.5 mm). Atolerance of 60.020 in.
