SDT dissipates static charges away from people and equipment in order to increase personal comfort and safety and help prevent sensitive equipment damage. In addition to static control, SDT offers the practical benefits of VCT, including durability, ease of maintenance and low installed cost. Post-installation electrical properties can be evaluated by a qualified third party. Contact your Armstrong representative for details. SDT is styled and constructed for use in light industrial, education and office applications, including computer classrooms and repair labs as well as electronic testing facilities. SDT provides static dissipative protection using a complete 4-part system. These components must be used together to obtain the static dissipative performance requirements. 1.

Colors and pattern are dispersed uniformly throughout the thickness of the material. Color pigments are insoluble in water and resistant to cleaning agents and light. Size (nominal) 12 in. x 12 in. (305 mm x 305 mm) Gauge (nominal thickness) 1/8 in. (3.2 mm) Limitations SDT should not be used in the following areas: ¦ Munitions facilities. ¦ Facilities containing explosives or explosive materials. ¦ Areas requiring conductive flooring. ¦ Hospital operating rooms. ¦ Heavy industrial and exterior areas. ¦ Commercial kitchens and commercial food processing areas. ¦ Where pointed spikes such as golf or track shoes will be used. ¦ Where the floor will be subjected to unusually concentrated static or dynamic loads. ¦ Do not install SDT in areas subjected to excessive surface water, such as areas where frequent spills are common. Excessive and/or prolonged exposure to surface water may interfere with the bond of SDT to the subfloor. If a surface spill occurs, it must be contained and removed immediately. Suitable for Application Over ¦ Concrete subfloors which are suspended, on grade or below grade. ¦ Suspended wood subfloor construction with approved wood underlayments, and a minimum of 18 in. (45.7 cm) well-ventilated air space below. ¦ Radiant-heated subfloors with a maximum surface temperature of 85° F (29° C). Unsuitable for Application Over ¦ Existing resilient flooring, ceramic, marble, terrazzo, metal or other nonporous substrates. ¦ Subfloors where excessive moisture or alkali is present. ¦ Sleeper-constructed wood subfloors, on grade or below grade. ¦ Lightweight aggregate concrete subfloors having a density of less than 90 lbs. per cu. ft. (1441 kg/m3) or cellular concrete having a plastic (wet) density less than 100 lbs. per cu. ft. (1602 kg/m3) [94 lbs. per cu. ft. (1506 kg/m3) dry weight], or concrete having a compressive strength of less than 3500 psi (24 MPa). Concrete slabs with heavy static and/or dynamic loads should have higher design strengths and densities calculated to accommodate such loads. Concrete curing agents, sealers, hardeners, or parting agents should be removed. TECHNICAL DATA Shipping Weight 63 lbs./carton (28.6 kg) – 45 tiles Gloss (typical value) 60 degrees specular – approximately 20 Reference Specifications ASTM F 1066 Class 2 – through pattern Meets requirements for size, thickness, squareness, indentation, impact, dimensional stability, resistance to chemicals, and resistance to heat. Static Load Limit ASTM F 970 75 lbs./sq. in. (5.27 kg/cm2) NOTE: Floors should be protected from sharp-point loads and heavy static loads. High-heeled traffic [1000 psi (70.3 kg/cm2) or more] may visibly damage wood, resilient and other floor coverings. LEED eligible under Credit EQ4.3 for Indoor Air Quality.

Ratings are not directly related to any one test. They are broadly based on tests and experience of Armstrong Research and Development under varying conditions and circumstances. These ratings should not be used for comparison to ratings used by other manufacturers to rank their own products.
