6.Test Methods
6.1Test Methods for Type I Glass(Transparent Flat Glass): 6.1.1Viewing Conditions for Blemish Detection—All visual inspections shall be made with20/20vision(naked eye or corrected).View samples in the vertical position at the distance as specified in the ctions following.The viewer shall be positioned perpendicular to the glass surface(Fig.2)using the following lighting unless otherwi specified:daylight(with-out direct sunlight)or other uniform diffud background lighting that simulates daylight,with a minimum luminance of 1700lux(160foot-candles)measured at the center of the glass surface.
6.1.1.1Blemish Detection for Point Blemish(Knots,Dirt, Stones,Crush,Gaous Inclusions,and Other Similar Blemishes)—Samples shall be viewed from a distance of approximately1m(39in.).If blemishes are detected,refer to Tables3and4for evaluation criteria.
6.1.1.2Point Blemish Measurement—Point blemish size shall be determined by measuring the maximum length and maximum perpendicular width of the blemish and calculating the average of th
e two dimensions.The allowable blemish sizes listed in Table3include associated distortion for Q1and Q2,but do not include associated distortion for Q3and Q4.
6.1.1.3Detection for Linear Blemishes(Scratches,Rubs, Digs,and Other Similar Blemishes)—Samples shall be viewed at the detection distance of3.3m(132in.).The inspection shall then progress quentially to each of the shorter distances for other applicable blemish intensities listed in Table10.Any blemishes detected from the distances shall be compared with the length and paration criteria for allowable blemishes given in Table5.
6.1.1.4Blemish Distribution—Separation between blem-ishes shall be determined by measuring the distance between the two clost points of the blemishes.For blemish size ranges with different paration distance criteria,the minimum pa-ration distance is determined by the minimum paration distance required for the larger of the two blemishes.Blem-ishes in size ranges that are allowed without paration distance criteria shall not be compared with tho that have paration criteria.
6.1.2Ream,Strings,Lines,and Distortion—(See Fig.1.) Place sample,with the direction of the draw oriented vertically, at a distance of approximately4.5m(15ft)from a zebra board with a measured illum
ination of215lux(20foot-candles) minimum with25-mm(1-in.)black-and-white diagonal stripes.Start with the glass sample parallel with the zebra board(identified as0°)and perpendicular with the viewer’s line of sight.Rotate the specimen clockwi from zero until
it
reaches the angle at which the distortion appears and report that angle as the vision interference angle.Refer to Table6for evaluation criteria.If the direction of draw cannot be deter-mined,then the sample shall also be viewed turning the sample 90°and evaluated as stated above.The lower of the two interference angles measured shall be ud to compare to the evaluation criteria in Table6.
6.1.3Dimensional Measurements—To measure the length and width of cut size and stock sheets offlat glass,measure the perpendicular distance from edge to edge,includingflares and bevels.
6.1.4Squareness Measurement—After measuring the length and width for compliance with dimensional tolerance, measure the length of both diagonals(corner to corner).The difference in leng
th between the two diagonals(D1–D2)shall not exceed the limits t forth in Table2.
6.1.5Solar/Optical Properties—If specified,the reflectance and transmittance of glass are to be determined in accordance with NFRC300.
6.2Test Methods for Type II Glass(Wired or Patterned Glass):
6.2.1Associated Distortion and Blemish Appraisal—Becau of the variety of us of patterned and wired glass, specific inspection guidelines are beyond the scope of this specification.Check with the manufacturer for more informa-tion.
6.2.2Dimensional Measurements—To measure the length and width of cut size and stock sheets offlat glass,measure the perpendicular distance from edge to edge,includingflares and bevels.Measurements taken at any point shall meet the tolerance requirements of Table7or Table8,or both.
6.2.3Point Blemish Measurement—Point blemish size shall be determined by measuring the maximum length and maxi-mum perpendicular width of the blemish and calculating the average of the two dimensions.The allowable blemish sizes listed in Table9do not include associated distortion.
Glass shall be viewed at distance of1.5m(59in.)normal to the glass surface with the light source approximating diffud daylight at 3m(118in.)behind the glass(e Fig.2).
6.2.4Solar/Optical Properties—For patterned and wired glass,consult with the manufacturer when the solar and optical properties are required.
6.2.5Measuring the Thickness of Patterned Glass—The thickness of patterned glass shall be determined by measuring high point to high point to the precision and accuracy in Table 8,using a measuring device with19-mm(3⁄4-in.)diameter or greater contact surfaces.As an alternate method,the thickness may be measured using two bars withflat and parallel surfaces 75mm(3in.)long or greater36mm(0.25in.)wide or greater 36mm(0.25in.)thick or greater.
7.Package Marking
7.1Each package of glass shall be identified by the manu-facturer and include the manufacturer’s name or trademark, nominal thickness,glass description,date of manufacture or date offinal packaging,and place of manufacture.
