Test Methods8.1 Conditionin
43、gCondition the test specimens in accor-dance with Procedure A of Method D 618 where conditioningis required.8.2 Length and WidthLay the panel on a flat, smoothsurface and measure with a steel tape. Measure the length onthe two sides and the center to the nearest 0.03125 in. (0.8mm), and average the
44、three measurements. Measure the widthon the projected width at each end and in the center to thenearest 0.03125 in., and average the three measurements.8.3 SquarenessAny type jig that has two rails perpendicu-lar to one another, each of length at least equal to the length ofthe side of the panel in
45、contact with the rail, may be used todetermine squareness. Place the panel in the jig so that thelongest edge of the panel touches the horizontal rail along itsentire length, and the vertical (short edge) touches the verticalrail at some point along its entire length. Measure the gapbetween the vert
46、ical rail and the short edge of the panel at thecorner opposite the one touching the rail. Measure to thenearest 0.03125 in. (0.8 mm). Rotate the panel 180 and repeatthe test.8.4 WeightWeigh the panel on a scale accurate to 61%.Calculate the area on the basis of length and width measure-ments made i
47、n accordance with 8.2. Calculate the weight inounces per square foot (or kilograms per square metre).8.4.1 ThicknessMake thickness measurements on flatpanels every 4 in. (101.6 mm) across the width of the panel, atboth ends, with a micrometer incorporating an anvil no lessthan 0.375 in. (9.5 mm) in
48、diameter and accurate to 0.001 in.(0.3 mm). Average the individual measurements in order todetermine the panels nominal thickness.8.5 PitchThe pitch of a profile of a panel is the averagedistance from the crest of one corrugation to the crest of anadjacent corrugation or, in the case of ribbed panel
49、s, thedistance from the center of one rib to the center of the nextadjacent rib. Determine the crests of the corrugations or ribs byplacing a metal straightedge crosswise on the panel so that ittouches the crests. Measure to within 60.0625 in. (65.2mm/m)/ft (304.8 mm) of panel width and divide by the numberof pitches to obtain an average pitch value.8.6 DepthThe depth of the corrugation is the verticaldistance between the plane of the crests and the upper side ofthe sheet at the bottom of the valley. Make ten depth measure-ments
