Materials and Manufacture6.1 Standard Commercial ProductA tread of the sameclassification shall, as a minimum, be in accordance with t
17、herequirements of this specification and shall be the manufactur-ers standard commercial product. A standard commercialproduct is a product that has been sold or is currently beingoffered for sale on the commercial market throughadvertisements, manufacturers catalogs, or brochures andrepresents the
18、latest production model.6.2 Tread DesignThe upper surface of tread shall haveone or a combination of 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 s
19、urface shall besmooth and flat.6.2.2 Class 2, Pattern: Embossed, Grooved, or RibbedWhen the surface is embossed, grooved or ribbed, the depth ofthe design shall not be greater than 50 % of the overallthickness of the tread.6.2.3 Group 1, Abrasive Strips (Embedded)Whenspecified, one or more mineral-c
20、oated abrasive grit strips, eachstrip not less than 0.030-in. (0.76 mm) thick, shall be recessedinto and adhered to the top surface of a smooth surface treadportion to form a continuous flat surface overall. Each stripshall run the full length of the treads and shall be parallel to thenose of the tr
21、ead. The front edge of the first strip shall be notmore than 1 in. (25.4 mm) from the nose of the step or landing.If a second strip is used, it shall be34 (19 mm) to 112 in. (38mm) from the first strip.6.2.4 Group 2, Contrasting Color for Visually ImpairedThe tread shall contain a strip of contrasti
22、ng color of either thesame material or an abrasive material.6.3 Nosing StyleNosing style shall be as specified (seeFigs. 1-3 for some typical styles).6.4 ColorAccording to manufacturers latest catalogs, andactual samples. Sample color may vary with age and storageconditions.7. Performance Requiremen
