Test Methods8.1 ConditioningCondition the test specimens in accor-dance with ProcedureAof Method D618 where conditioning isrequired.8.2 Length and WidthLay th

42、e 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 three measurements. Measure the widthon the projected width at each end and in the center to thenearest 0.03125 in., and average the t

43、hree 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 contact with the rail, is acceptable foruse to determine squareness. Place the panel in the jig so thatthe longest edge of the panel t

44、ouches the horizontal rail alongits entire length, and the vertical (short edge) touches thevertical rail at some point along its entire length. Measure thegap between the vertical rail and the short edge of the panel atthe corner opposite the one touching the rail. Measure to thenearest 0.03125 in.

45、 (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 in accordance with 8.2. Calculate the weight inounces per square foot (or kilograms per square metre).8.4.1 ThicknessMake thi

46、ckness measurements on flat pan-els every 4 in. (101.6 mm) across the width of the panel, at bothends, with a micrometer incorporating an anvil no less than0.375 in. (9.5 mm) in diameter and accurate to 0.001 in. (0.3mm). Average the individual measurements in order to deter-mine the panels nominal

47、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 panels, thedistance from the center of one rib to the center of the nextadjacent rib. Determine the crests of the corrugation

48、s 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 betwee

49、n the plane of the crests and the upper side ofthe sheet at the bottom of the valley. Make ten depthmeasurements, five at each end, to the nearest 0.03125 in. (0.76mm) with a depth micrometer on each specimen and averagethe results.8.7 ColorExamine the panel visually from a distance of10 ft (3 m) for color uniformity by viewing. Minor differencesin intensity of the color due to the uneven dispersion of theglass fibers in the resin shall not be cause for rejection.TABLE 1 Physical PropertiesAProperty ValueBASTMTest Metho
