It is important that you be aware of legal ramifications of asbestos in your roofing system before any work is planned. 2 of 4 ACT ANALYTICAL REPORT FOR ARLINGTON SCHOOL DISTRICT ASBESTOS CORE TESTING Core: Gymnasium, Field, Core 1 Identification Number:3082TH009 NVLAP Test Code: 18/A01 Treatment: Methylene Chloride Solvent Extraction NVLAP Lab Code: 200887-0 Homogeneity: Layered Test Method: EPA/600/R-93/116 & EPA-600/M4-82-020 Layer Color Asbestos Other Fibrous Nonfibrous One gray Chrysotile 70 Cellulose 20 Binder 10 Two white None Detected Fiberglass 95 Binder 5 Three white None Detected Fiberglass 95 Binder 5 Four white None Detected Fiberglass 95 Binder 5 Five white None Detected Polyester 15 Binder 85 MASTIC None Detected Asphalt 100 TOTAL Chrysotile 5 Fiberglass 3 Asphalt 63 Cellulose 2 Binder 26 Polyester 1 Notice: The results of this analysis are based on findings determined from laboratory analysis of individual roof core samples and include the inherent uncertainty of measurement for estimating percentages by polarized light microscopy.
