Ma
30、terials and Manufacture6.1 The product is a laminated resilient flooring structureconsisting of a wear surface, a visual dcor, a rigid polymericcore designed to give added stiffness to the finished flooring,good water resistance, and if the product utilizes profilededges, good joint strength. The pr
31、oduct can be manufacturedwith or without an attached underlay backer for better noisereduction and to help with accommodating minor subfloorirregularities.6.2 MaterialThe wear surface of the resilient tile(s) orplank(s) shall be composed of binder, filler, and pigmentscompounded with suitable lubric
32、ants and processing aids. Thebinder consists of one or more polymers or copolymers of vinylchloride, other modifying resins, plasticizers, and stabilizers,which comprise at least the following minimum percentweight: The polymers or copolymers of vinyl chloride com-prise at least 60 % of the weight o
33、f the binder. Any copolymerof vinyl chloride used shall contain at least 85 % vinylchloride. The backer layer, core, and dcor layer may beexempt from having to be polyvinyl chloride (PVC)-basedpolymer, but they shall use polymeric binder and meet thebinder levels referenced in the Table 1 requiremen
34、ts. Productsmay utilize an underlay attached to the resilient flooringproduct described in this specification.Attached underlays mayinclude products such as cork, IXPE foam, etc. provided theTABLE 1 Minimum Binder ContentClass IClear wear layer 90 %Base/inter layer(s) 30 %AASingle composite average

Attached underlay is excluded from bindercontent requirement.F3261 172finished resilient flooring product, with the attached underlaymeets all requirements of this product specification.6.3 Class, Type, and Pattern N
36、umberThe class, type, andpattern number, as applicable, shall be as specified in thecontract or order (see 4.1).NOTE 1The patterns that are available are indicated in individualmanufacturers current catalogs or on the manufacturers website.6.4 Printed Tile or PlankThe structure of printed luxuryviny
37、l plank (LVP) and luxury vinyl tile (LVT) are formed of avinyl wear layer, which may be transparent or translucent. Thepattern and colors are created by a print or other surfacedecoration between the wear layer and the intermediate coloredlayer or polymeric core layer. Other base layers may be added
38、.Products shall comply with Table 1 for binder content.6.4.1 For commercial applications, the wear layer shall be aminimum of 0.020 in. (0.5 mm) thick.6.4.2 Non-PVC LayerThe top layer(s) of a product can bea non-PVC layer(s), which may constitute part of the total wearlayer system up to 49 % and is
39、not removable by normalmaintenance procedures. Non-PVC compositions (specialtyperformance layer(s) used as the top layer) are not described bybinder limits.7. Physical Requirements7.1 Binder ContentThe binder content shall be determinedby a statement of formula (manufacturer certificate of compli-an
40、ce).7.2 SizeThe products are available in a range of sizes.Unless otherwise specified (see 5.1.4), for dimensions 12 in.(305 mm) or smaller, a size tolerance of 60.016 in. (0.4 mm)will be allowed. For dimensions larger than 12 in. (305 mm),but smaller than or equal to 18 in. (457 mm), a size toleran
41、ceof 60.018 in. (0.45 mm) will be allowed. For dimensionslarger than 18 in. (457 mm), a size tolerance of 60.020 in. (0.5mm) will be allowed when measured in accordance with TestMethod F2055 for tiles and certain size planks when appli-cable. Certain specialty items may be available in other sizes.P
42、lanks will follow same basic guidelines based on allowablesize tolerance. Planks utilize ISO 24337 for size measurement.For plank length 24 up to 48 in. (610 up to 1220 mm), a sizetolerance of 60.060 in. (1.5 mm) will be allowed, and forplank length 48 in. (1220 mm) or greater, a size tolerance of60
