PROJECT NO: 4140 92-2757 DATE: July 23, 1993 <br /> PAGE: 5 <br /> TEST �tETHODS: 1 <br /> TestinQ <br /> All tests were conducted as referenced in ASTNi:C578-87a. <br /> am lin <br /> Two 4' x 8' sheets of EPS thermal insulation were submitted for each ASTM C578 classification of EPS <br /> insulation evaluated. Each 4' x 8' sheet was sub-divided into two 2' x 8' sheets. One of these was used <br /> as the control, for testing of initial properties. The other three were applied to the foundation wall. One <br /> sample of each EPS type was removed annually over the next three years. <br /> From each 2' x 8' sample removed, three 12" x 12" specimens were tested for density and thermal <br /> resistance. One near the top of the 8' length, one near the bottom, and one near the center. <br /> Sample Installation ' <br /> The test samples were applied to the exterior of the below grade foundation of Twin City Testing's <br /> , Cromwell Avenue building on September 21, 1989. The temperature on the inside of this foundation wall <br /> � is maintained at 70±5°F. Three 2' by 8' pieces of ASTM C578 type I and type II EPS were installed with <br /> the 8' length vertical. The top of each sample was placed just under ground level and the samples were <br /> held in place by back fill. The soil used to back.fill has a final grade of '/z" per foot and had the following <br /> characteristics: <br /> Classification: Sand with silt and gravel, medium to fine grain. <br /> Density, lb/ft': � 112.3 � <br /> Moisture Content, %: 7.9 (1.06 gallons water/ft3 soil) <br /> Coefficient of Permeability <br /> at 20°C, fVmin: 6.0 x 10-3 <br /> Mechanical Analysis <br /> Percent Finer Than: 3/4" 100.0 <br /> 3/8" 96.1 <br /> f�4 90.3 <br /> �10 82.9 <br /> #40 35.4 <br /> #100 14.9 <br /> ' /l200 10.9 <br /> aS A 4tU�Ual PRCTcC��ON TO CUENTS THE PUBUC AND OURScLVES.AlL iDVIN GTV TESTING CORPOR4iiON REPORTS a�E SUBM�TTED AS TME CONFIOENTiAL PROPERTV OP rUE'7T5 <br /> ATJO aU�MC�7QA71ON:OR PU9l'GTIGN Of S��1T��,1ENiS.CONCIUS�ONS OA EXTqqCT10N5 F�70M OR GiEGnRDING OUR REPORTS IS RESERVED PENOWG OUR PFIOR WRITT�;V A?oq0`:AL <br />
