Happy Feet, International CLIENT <br />II 11 II II II II I III <br />IDENTIFICATION Iron man <br />CONSTRUCTION LVP <br />ASTM E648 Standard Test Method for Critical Radiant Flux of Floor <br />Covering Systems Using A Radiant Heat Energy Source, also referenced <br />as NFPA 253 and FTM Standard 372 <br />TEST METHOD CONDUCTED <br />DESCRIPTION OF TEST SAMPLE <br />GENERAL PRINCIPLE <br />This procedure is designed to measure the critical radiant flux at flame out of horizontally mounted floor <br />covering systems exposed to a flaming ignition in a test chamber which provides a graded radiant heat energy <br />environment. The imposed radiant flux simulates the thermal radiation levels likely to impinge on the floors of a <br />building whose upper surfaces are heated by flames from a fully developed fire in an adjacent room or <br />compartment. The test result is an average critical radiant flux (watts/square cm) which indicates the level of <br />radiant heat energy required to sustain flame propagation in the flooring system once it has been ignited. A <br />minimum of three test specimens are tested and the results are averaged. Theoretically, if a room fire does not <br />impose a radiant flux that exceeds this critical level on a corridor floor covering system, flame spread will not occur. <br />The NFPA Life Safety Code 101 specifies as Class 1 Critical Radiant Flux of .45 watts/sq cm or higher and <br />Class 2 Critical Radiant Flux as .22 - .44 watts/sq cm. <br />FLOORING SYSTEM ASSEMBLY <br />SUBSTRATE Mineral-Fiber/Cement Board I UNDERLAYMENT Direct Glue Down <br />CONDITIONING Minimum of 96 hours at 70 ±5°F and 50 ± 5% <br />relative humidity <br />Advanced Adhesive 272 ADHESIVE <br />APPROVED BY: <br />A <br /> <br />TE TING <br />NVLAP LAB CODE 100297-0 PJLA TESTING LAB CODE 93341j <br />P Professional <br />Testing <br />Laboratory <br />Inc. <br />DATE:11-08-2019 <br />TEST REPORT <br />Page 1 of 1 TEST NUMBER:0261306 <br />Distance Burned Time To Flame Out Critical Radiant Flux <br />Specimen 1 12 cm 5 minutes 1.07 watts/square cm <br />Specimen 2 13 cm 5 minutes 1.05 watts/square cm <br />Specimen 3 13 cm 5 minutes 1.05 watts/square cm <br />Average Critical Radiant Flux 1.06 Watts/Square Cm <br />Standard Deviation 0.01 Watts/Square Cm <br />Coefficient of Variation 0.89 % <br />TE: Meets or exceeds Class I rating as specified in NFPA Life Safety Code 101. <br />4., <br />This facility is accredited by the National Voluntary Laboratory Accreditation Program for the specific scope of accreditation under <br />Lab Code 100297.This accreditation does not constitute an endorsement, certification, or approval by NIST or any agency of the <br />United States Government for the producttested.
