1. Scope
1.1 This specification covers requirements for the com- pound and physical characteristics of cork floor tile. This standard specifies the requirements for cork floor coverings made from agglomerated composition cork supplied in tile form, which are designed to be used with a factory finish or an in situ finish, or both. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appro- priate safety, health, and environmental practices and deter- mine the applicability ofregulatory limitations prior to use. 1.4 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Terminology
3.1 Definitions—For definitions of terms used in this standard, see Terminology F141. 3.2 agglomeratedcork—product obtained from the blending of cork granules with the addition of a binder. The percentage of cork, by weight, shall be >90 %.
4. Classification
4.1 Class—Type: cork floor tile covered by this specifica- tion shall have a smooth surface and be classified as follows: 4.1.1 Class I—Homogeneous Cork Tile (6.1) Type A—Unfinished (specify details of staining or site finishing, or both) Type B—Factory finished (specify per manufactur- er’s product information) 4.1.2 Class II—Heterogeneous Cork Tile (6.2)
6. Materials and Manufacture
6.1 Class I—Homogeneous Cork Tile – Homogeneous cork tile shall be of uniform structure and composition throughout, consisting of cork granules thoroughly and uniformly bonded together. 6.2 Class II—Heterogeneous Cork Tile – The pattern of this tile comprises a veneer layer ofcork and a base layer consisting of cork granules thoroughly and uniformly bonded together. The pattern of this tile need not extend throughout the entire thickness of the tile.
7. Physical Properties
7.1 Squareness—When tested in accordance with Test Method F2055, cork floor tile squareness variation shall not exceed 0.02 in. (0.5 mm). 7.2 Thickness—When tested in accordance with Test Method F386, thickness variation shall not exceed 60.01 in. (60.25 mm). 7.3 Size—When measured in accordance with Test Method F2055, a tolerance of 60.016 in. (0.4 mm) per tile shall be permitted. 7.4 Apparent Density—Shall be ≥28 lb/ft 3 (450 kg/m 3 ) when tested in accordance with EN 672. 7.5 Curling—When tested in accordance with EN 434, shall curl less than 0.236 in. (6 mm). 7.6 Moisture Content—Shall be >4.5 % and <6 %, when tested per manufacturer’s guidelines. 7.7 Flexibility—When tested in accordance with Test Method F137 and a mandrel size of 2-in. (50.8 mm), the tile shall show no cracks or breaks.
8. Performance Requirements
8.1 Castor Chair Test—When tested in accordance with ISO 4918 after 20 000 cycles, for commercial use, no disturbance to the surface other than slight change in appearance and no delamination shall occur. 8.2 Static Load Resistance—When tested in accordance with Test Method F970, with an applied load of 250 lb (113.4 kg), the residual indentation shall not be greater than 0.005 in. (0.127 mm). 8.3 Residual Indentation—When tested in accordance with Test Method F1914, under 30-lb (13-kg) load, 0.25-in. (6.35- mm) flat foot and 10 min indentation, the average residual indentation at the end of60-min recovery shall not exceed 8 %, and the maximum residual indentation of any single specimen shall not exceed 10 %. 8.4 Dimensional Stability—When tested in accordance with Test Method F2199, the tile shall not change in linear dimen- sion more than 0.020 in./linear ft (0.51 mm/305 mm). 8.5 Abrasion Resistance—When tested per the method de- scribed in ISO 24338–Method A, cork floor tile shall pass at ≥4000 revolutions for commercial use. 8.6 Resistance to Chemicals—The chemical resistance of cork floor tile shall be determined in accordance with Test Method F925. The cork floor tile shall have no more than a slight change in surface dulling, surface attack, or staining when exposed to the following chemicals: 8.6.1 White Vinegar (5 % acetic acid). 8.6.2 Rubbing Alcohol (70 % isopropyl alcohol). 8.6.3 White mineral oil (medicinal grade). 8.6.4 Household ammonia solution (5 % NH 4 OH). 8.6.5 Household bleach (5.25 % NaOCl). 8.6.6 Disinfectant – phenol type (5 % active phenol). N OTE 1—These chemicals are representative of those most likely to be found in domestic, commercial, and institutional use. Many proprietary compounds contain one or more of these chemicals. Should the flooring for an unusual application need to be resistant to a specific chemical, this additional requirement should be part of the procurement document.
