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 (29 kg) Packaging Tiles per carton – 45, 45 sq. ft. Gloss (typical value) 60 degrees specular: 20 - 40 Reference Specifications ASTM F 1066, Class 3 – surface pattern ISO 9001 LEED eligible under CONSEILDUBATIMENT DURABLEDUCANADA CANADAGREENBUILDINGCOUNCIL Quality Credit EQ4.3 for Management Indoor Air Quality Standard MEMBER / MEMBRE Static Load Limit ASTM F 970 125 lbs./sq. in. (8.8 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. Comparative Subjective Property Ratings Durability – Good Maintainability – Good Resilience – Good Subjective ratings (excellent, very good, good, fair) are in relation to other Armstrong commercial resilient floors. 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. Fire Test Data ASTM E 648 Flooring Radiant Panel Critical Radiant Flux – 0.45 watts/cm2 or more – Class I ASTM E 662 Smoke Chamber Specific Optical Smoke Density – 450 or less Numerical flammability ratings alone may not define the performance of the product under actual fire conditions. These ratings are provided only for use in the selection of products to meet the specified limits. INSTALLATION Job Conditions Subfloors/underlayments shall be dry, clean, and smooth. They shall be free from paint, varnish, solvents, wax, oil, existing adhesive residue, or other foreign matter. For more detailed requirements of concrete, wood and metal subfloors, as well as wood and trowelable underlayments, refer to Armstrong Guaranteed Installation Systems manual, F-5061. Calcium Chloride Tests for moisture must be conducted. Armstrong offers a guideline of a maximum acceptable moisture emission level of 5.0 lbs. per 1000 sq. ft. per 24 hours. Bond Tests should also be conducted for compatibility with the substrate. When testing for alkalinity, the allowable readings for the installation of Armstrong flooring are 5 to 9 on the pH scale. Temperature shall be maintained at a minimum of 65° F (18° C) and a maximum of 100° F (38° C) for 48 hours prior to installation, during installation and 48 hours after completion. A minimum temperature of 55° F (13° C) shall be maintained thereaf...
