20、)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 is embossed, grooved or ribbed, th
21、e 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 into and adhered to the top surface
22、 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 the step or landing. If a second st
23、rip is used,it shall be 34 (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 be as specified (see Figs. 1-3 f
24、or 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 HardnessThe treads shall have a durometer hardness as follows:Grade 1 85Grade 2 70 but less than 85 (Shore, Type A, ins
25、tantaneous reading) when tested in accordance with Test Method D2240.FIG. 1 Round NoseF2169 1427.2 Molded Stair TreadsThe bonding surface of the tread shall be sanded, roughened, or otherwise modified by themanufacturer to remove substances that may interfere with proper adhesion.7.3 Tread BacksUnle
26、ss otherwise specified in the contract or order, the back or bonding surface of the rubber tread shall besanded, buffed, roughened, ribbed/grooved, or otherwise modified to ensure proper adhesion.7.4 Resistance to Chemicals, Short-Term ExposureWhen tested in accordance with Test Method F925, the vin
27、yl 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 % Acetic Acid)Rubbing Alcohol (70 % Isopropyl Alcohol)White Mineral Oil (Medicinal Grade)Sodium Hydroxide Solution (5 % NaOH)Hydrochlori
28、c Acid Solution (5 % HCl)Sulfuric Acid Solution (5 % H2SO4)Household Ammonia Solution (5 % NH4OH)Household Bleach Solution (5.25 % NaOCl)Olive Oil (light)Unleaded Gasoline (regular grade)Disinfectant Cleaner (5 % Phenol)Kerosene (K1)NOTE 1These basic chemicals are representative of those likely to b
29、e found in domestic, commercial, and institutional use. Many proprietarycompounds contain one or more of these basic chemicals. Should the rubber or vinyl tread for an unusual application need to be resistant to a specificchemical, this additional requirement should become part of the procurement do
30、cument.7.5 Resistance to HeatWhen tested in accordance to Test Method F1514, the color change of the resilient stair treads shallhave an average E not greater than 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
31、 a test method to addressthis requirement. Existing Q-UV and Xenon-Arc test methods used to test rubber floor tiles tiles, rubber sheets and rubber stairtreads resulted in extremely high failure rates,rates which isare not typical in everyday use of these products.8.
