20、the following:Class 1 Smooth (Flat)Class 2 Pattern: Embossed, Grooved, or RibbedGroup 1 Abrasive Strips: EmbeddedGroup 2 Contrasting Color for Visually Impaired6.2.1 Class 1, Smooth (Flat)The tread surface shall be smooth and flat.6.2.2 Class 2, Pattern: Embossed, Grooved, or RibbedWhen the surface
21、is embossed, grooved or ribbed, the depth of thedesign shall not be greater than 50 % of the overall thickness of the tread.6.2.3 Group 1, Abrasive Strips (Embedded)When specified, one or more mineral-coated abrasive grit strips, each strip not lessthan 0.030-in. (0.76 mm) thick, shall be recessed i
22、nto and adhered to the top surface of a smooth surface tread portion to form acontinuous flat surface overall. Each strip shall run the full length of the treads and shall be parallel to the nose of the tread. Thefront edge of the first strip shall be not more than 1 in. (25.4 mm) from the nose of t
23、he step or landing. If a second strip is used,it shall be34 (19 mm) to 112 in. (38 mm) from the first strip.6.2.4 Group 2, Contrasting Color for Visually ImpairedThe tread shall contain a strip of contrasting color of either the samematerial or an abrasive material.6.3 Nosing StyleNosing style shall
24、 be as specified (see Figs. 1-3 for some typical styles).6.4 ColorAccording to manufacturers latest catalogs, and actual samples. Sample color may vary with age and storageconditions.7. Performance Requirements7.1 HardnessTreads shall meet a ShoreADurometer reading of not less than 85 when tested ac
25、cording to Test Method Thetreads shall have a durometer hardness as follows:FIG. 1 Round NoseF2169 122Grade 1 $ 85Grade 2 $ 70 but less than 85 (Shore, Type A, instantaneous reading) when tested in accordance with Test Method D2240.7.2 Molded Stair TreadsThe bonding surface of the tread shall be san
26、ded, roughened, or otherwise modified by themanufacturer to remove substances that may interfere with proper adhesion.7.3 Tread BacksUnless otherwise specified in the contract or order, the back or bonding surface of the rubber tread shall besanded, buffed, roughened, ribbed/grooved, or otherwise mo
27、dified to ensure proper adhesion.7.4 Resistance to Chemicals, Short-Term ExposureWhen tested in accordance with Test Method F925, the vinyl and rubbertreads shall have no more than a slight change in surface dulling, surface attack, or staining when exposed to the followingchemicals:White Vinegar (5

29、Gasoline (regular grade)Disinfectant Cleaner (5 % Phenol)Kerosene (K1)NOTE 1These basic chemicals are representative of those likely to be found in domestic, commercial, and institutional use. Many proprietarycompounds contain one or more of these basic chemicals. Should the rubber or vinyl tread fo
30、r an unusual application need to be resistant to a specificchemical, this additional requirement should become part of the procurement document.7.5 Resistance to HeatWhen tested in accordance to Test Method F1514, the color change of the resilient stair treads shallhave an average DE not greater tha
31、n 8.0 after 7 days exposure to 158F (70C).7.6 Resistance to LightTask Group F06.80.13 will continue to search for a test method or develop a test method to addressthis requirement. Existing Q-UV and Xenon-Arc test methods used to test rubber floor tiles resulted in extremely high failure rates,which
32、 is not typical in everyday use of these products.8. Dimensions and Permissible Variations8.1 Dimensions of Rubber and Vinyl TreadsRubber and vinyl tread dimensions shall be as specified.
