5试验方法

5.1长度和宽度尺寸偏差的测定

用符合GB/T9056钢直尺或钢卷尺，分别从长宽边的中间部位，测量两平行边的距离。测得的结果与公称尺寸的差值即为尺寸偏差。

5.2对角线差的测定

用钢卷尺测量玻璃板的两条对角线，取其差的绝对值。

5.3厚度偏差的测定

用符合GB/T1217规定的精度为0.01mm且圆盘直径不低于20mm的公法线千分尺在玻璃板四边中点测量。取其最大偏差值。5.4外观质量的测定

5.4.1

将玻璃板垂直放置在支架上，在起后边相距0.6m是一无反光灰色屏幕。玻璃板与屏幕间用若干盏40W日光灯照亮，日光灯发出的光线不能与玻璃板垂直。观察者在距离玻璃板0.6m左右处垂直观察。缺陷尺寸的大小以能看清楚的最大边缘为限，采用符合GB/T9056精度为1mm的钢直尺和放大10倍或10倍以上、精度不低于0.1mm的读数显微镜测量。5.4.2

用符合GB/T9056的刚直尺测量。凹凸时测量边部凹进或凸出最大部位与板边之间的距离；爆边时测量边部凹进最大部位与板边之间的距离；缺角时测量原角等分线的长度。5.4.

将玻璃垂直放置，不施加外力，沿玻璃非压花面放置1000mm长的直尺，用符合JB/T8788的塞尺测量钢直尺边与玻璃板之间的最大间隙。玻璃弓形弯度时，测量对应弦长的弦高；波形时，测量对应两波峰间的波谷深度，按式（1）计算弯曲度c=h/L*100…………（1）

式中：c——弯曲度，%；h——弦高或波谷的深度，mm；L——弦长或波峰到波峰的距离，mm。5.4.4可见光透射比测定的按GB/T2680中的规定执行。检验规则产品出厂应检验5.1~5.5项目。6.2产品应由公司质量检验部门按本标准的规定进行检验，合格后附产品质量合格证方可出厂。6.3当对产品质量有争议时、以及监督抽查、仲裁时可按本标准表2规定的玻璃批量和抽样数抽样。抽样表依据GB/T2828.1，取AQL=6.5。表2抽样表批量范围样本大小合格判定数不合格判定数1~82019~1530116~5081251~90132391~1502034151~2803256281~5005078501~1200801011判定规则

6.4.16.4.27包装、标志、运输与贮存7.1玻璃用木箱或集装架（箱）包装，木箱包装应符合JC/T513；集装架（箱）应符合GB/T6382.1和GB/T6382.2的要求。在同一木箱或集装架（箱）内，玻璃有花纹的一面应朝向同一侧。7.2木箱或集装架（箱）应附有产品质量合格证，标明产品等级、花型、尺寸、厚度、数量、生产日期、本标准号、生产厂名、注册商标或花纹朝向。7.3运输时应防止木箱或集装架（箱）倾倒碰撞。7.4玻璃应贮存在干燥并有防雨设施的地方。StandardofQualityInspection1.RangeThestandardstipulatetheclassification,technicalrequirements,testmethod,inspectionrulesandpackaging,marking,transportation,storage,etcofextrawhiteglassThestandardapplytosingle-sidedextrawhiteglasswhichproduceby连续辊压工艺.Double-sidedextrawhiteglassalsocanrefertothisstandardasreference
