Test Methods <br />Quality Assurance & Testing <br />A 2 8 2014 <br />IMENTAL HEALTH <br />PAPTMENT <br />10.1 The tanks of the same material furnished under this Section shall be supplied by a <br />manufacturer who has been regularly engaged in the design and manufacturing of <br />rotationally molded polyethylene chemical storage tanks using cross-linked and high density <br />linear polyethylene tanks for over ten years. <br />10.2 Dimensions and Tolerances <br />10.2.1 All dimensions will be taken with the tank in the vertical position, unfilled. Tank <br />dimensions will represent the exterior measurements. <br />10.2.3 The tolerance for the outside diameter, including out of roundness, shall be per <br />ASTM D1998. <br />10.2.4 The tolerance for fitting placements shall be +/- 0.5 in. in elevation and 2 degrees <br />radial at ambient temperature. <br />10.3 Test Methods <br />Test specimens shall be taken from fitting location areas. <br />10.3.1 Low Temperature Impact Test <br />10.3.2 Test specimens shall be conditioned at (- 40) degrees Fahrenheit for a minimum of 2 <br />hours. <br />10.3.3 The test specimens shall be impacted in accordance with the standard testing <br />methods as found in ASTM D1998. Test specimens <'/2" thickness shall be tested at 100 ft. <br />Ib. Test specimens > '/2" thickness shall be tested at 200 ft. Ib. <br />10.4 Degree of Crosslinking Test (% Gel — Type I Resin Only) <br />10.4.1 The test method used is to be the o -xylene insoluble fraction (gel test) per ASTM <br />D2765 Method C. This test method is for determination of the ortho-xlene insoluble fraction <br />(gel) of crosslinked polyethylene. <br />10.4.2 The percent gel level for Type I tanks on the inside 1/8 in. of the wall shall be a <br />minimum of 65%. <br />10.5 Ultrasonic Tank Thickness Test <br />
