5試驗方法

5.1長度和寬度尺寸偏差的測定

用符合GB/T9056鋼直尺或鋼卷尺，分別從長寬邊的中間部位，測量兩平行邊的距離。測得的結(jié)果與公稱尺寸的差值即為尺寸偏差。

5.2對角線差的測定

用鋼卷尺測量玻璃板的兩條對角線，取其差的絕對值。

5.3厚度偏差的測定

用符合GB/T1217規(guī)定的精度為0.01mm且圓盤直徑不低于20mm的公法線千分尺在玻璃板四邊中點測量。取其最大偏差值。5.4外觀質(zhì)量的測定

5.4.1

將玻璃板垂直放置在支架上，在起后邊相距0.6m是一無反光灰色屏幕。玻璃板與屏幕間用若干盞40W日光燈照亮，日光燈發(fā)出的光線不能與玻璃板垂直。觀察者在距離玻璃板0.6m左右處垂直觀察。缺陷尺寸的大小以能看清楚的最大邊緣為限，采用符合GB/T9056精度為1mm的鋼直尺和放大10倍或10倍以上、精度不低于0.1mm的讀數(shù)顯微鏡測量。5.4.2

用符合GB/T9056的剛直尺測量。凹凸時測量邊部凹進或凸出最大部位與板邊之間的距離；爆邊時測量邊部凹進最大部位與板邊之間的距離；缺角時測量原角等分線的長度。5.4.

將玻璃垂直放置，不施加外力，沿玻璃非壓花面放置1000mm長的直尺，用符合JB/T8788的塞尺測量鋼直尺邊與玻璃板之間的最大間隙。玻璃弓形彎度時，測量對應弦長的弦高；波形時，測量對應兩波峰間的波谷深度，按式（1）計算彎曲度c=h/L*100…………（1）

式中：c——彎曲度，%；h——弦高或波谷的深度，mm；L——弦長或波峰到波峰的距離，mm。5.4.4可見光透射比測定的按GB/T2680中的規(guī)定執(zhí)行。檢驗規(guī)則產(chǎn)品出廠應檢驗5.1~5.5項目。6.2產(chǎn)品應由公司質(zhì)量檢驗部門按本標準的規(guī)定進行檢驗，合格后附產(chǎn)品質(zhì)量合格證方可出廠。6.3當對產(chǎn)品質(zhì)量有爭議時、以及監(jiān)督抽查、仲裁時可按本標準表2規(guī)定的玻璃批量和抽樣數(shù)抽樣。抽樣表依據(jù)GB/T2828.1，取AQL=6.5。表2抽樣表批量范圍樣本大小合格判定數(shù)不合格判定數(shù)1~82019~1530116~5081251~90132391~1502034151~2803256281~5005078501~1200801011判定規(guī)則

6.4.16.4.27包裝、標志、運輸與貯存7.1玻璃用木箱或集裝架（箱）包裝，木箱包裝應符合JC/T513；集裝架（箱）應符合GB/T6382.1和GB/T6382.2的要求。在同一木箱或集裝架（箱）內(nèi)，玻璃有花紋的一面應朝向同一側(cè)。7.2木箱或集裝架（箱）應附有產(chǎn)品質(zhì)量合格證，標明產(chǎn)品等級、花型、尺寸、厚度、數(shù)量、生產(chǎn)日期、本標準號、生產(chǎn)廠名、注冊商標或花紋朝向。7.3運輸時應防止木箱或集裝架（箱）傾倒碰撞。7.4玻璃應貯存在干燥并有防雨設(shè)施的地方。StandardofQualityInspection1.RangeThestandardstipulatetheclassification,technicalrequirements,testmethod,inspectionrulesandpackaging,marking,transportation,storage,etcofextrawhiteglassThestandardapplytosingle-sidedextrawhiteglasswhichproduceby連續(xù)輥壓工藝.Double-sidedextrawhiteglassalsocanrefertothisstandardasreference
