Johnson Matthey standard test conditions for glass enamels:玻璃釉料标准测试条件：Firing Conditions:烧结条件：The firing conditions are assessed on a Centrotherm belt furnace, 3 zones, time in kiln（including cooling） 25 minutes. Set temperature of zones 1, 2 and 3 are mentioned as firing temperature glass enamel. These values should be used for comparative purposes only and do not refer to firing temperatures under production circumstances。使用Centrotherm 三段式带式炉，将样品在炉内烧25分钟（包括冷却时间）评估其烧结条件。区域1，2和3的设定温度为该样品釉料的烧结条件。其值仅用作参考，而不作为实际生产条件。Typical specification: depending on enamel type, no general specification.标准参数：无，取决于釉料类型。Thermal Expansion:热膨胀：The Thermal Expansion Coefficient(TEC) is determined by measuring the expansion of the glass enamel between 20 and 320.The sample is prepared by pressing glass enamel powder into a mould and fire until it is completely fused. The sample is then measured on an Electrotech dilatometer.通过测量釉料样品在20到320度之间的膨胀情况确定其膨胀系数。样品准备：将玻璃釉料粉未压入一模具内，加热直至其完全熔化。然后利用膨胀仪测量样品。Typical specification: Depending on enamel type, but close to the TEC of glass.标准规格： 取决于釉料类型，但必须接近玻璃的膨胀系数。Light Transmission:透光率（遮盖力）：The light transmission (UV and Visual) are determined using a Gretag D200 optical density meter. The printed (wet layer thickness) is 25um.使用D200型光学密度计测量透光率，湿膜厚度为25um样品确定该釉料的遮盖力。Typical specification: Depending on enamel type, but usually15N标准：15N.Fineness of paste:油墨细度：The fineness of the paste is determined using a Hegmann gauge. See the picture below for the equipment used at Johnson Matthey b.v. to determine the fineness of the paste. 用细度规测量油墨的细腻度。下图为庄信万丰用来测量油墨细腻度设备。Typical specification: 30um 通用标准：30um. Viscosity:粘度：The viscosity is measured using a TA instruments AR500. The measuring system we use for QC is a 4cm, 4spindle. The temperature of the cone, plate and the sample is 21(unless mentioned otherwise). We read the viscosity at a shear rate of 1008/s.In the picture below you can see the TA instruments AR500 equipment.使用AR500测量油墨粘度。目前，品质控制所用测量系统为一4cm,4度转子。如无特殊要求，其试验温度为21（包括样品，转子及放置样品托盘）. 剪切率为1008每秒时的读数为油墨粘度值。下图为AR500仪器图片。Typical specification: Depending on enamel type, no general specification.标准：取决于油墨类型，无通用标准。Surface Appearance:表面光洁度：The gloss of a surface is measured under an angle of 85using Microtrigloss equipment as shown below. Matt surfaces have a low gloss value while glossy enamels can reach up to a gloss value of 100.利用相关设备以85度角方向测量光泽度。无光泽表面光泽度值小，而亮光油墨其光泽度值可达100.Typical specification: Depending on paste type, no general specification, low for matt enamels, high for glossy enamels.标准：取决于油墨类型，亚光油墨光泽度值低，亮光油墨光泽度值高。备注：以上须油墨良好印刷，烘干并烧结。Surface Roughness:表面粗糙度：The fired surface roughness is measured using a TR100 surface roughness tester. Below a picture of the equipment used within Johnson Matthey b.v.庄信万丰使用TR100表面粗糙度测试仪测量烧结后油墨表面粗糙度。Typical specification: Comparative to standard ( roughness 1.0um)规格：相对于标准件0.1um.Chemical Durability:耐化学试剂（耐酸碱）Chemical durability can be tested using difference methods. This results in different values, depending on the assessment type used.耐化学性有多种不同测试方法。基于不同测试方法产生有不同值。In the table below an overview of the most common tests is given.下表概括出最常用几种测试。Typical specification: Depending on enamel type, no general specification.无通常标准，取决于油墨类型。Chemical used(所用试剂)Time（时间）Temperature（温度）Assessment判定标准3.5% HCL(3.5%盐酸)15minute(分钟)Room temperature室温ASTM C724-913.7% HCL(3.7%盐酸)5 minutes(分钟)Room temperature室温ASTM C724-915%HCL(5%盐酸)5 minutes(分钟)Room temperature室温ASTM C724-9110%Citric(10%柠檬酸)15minute(分钟)Room temperature室温ASTM C724-910.1N 硫酸4,24,72and 144hours80摄氏度Visual in daylight,ok=no change in colour.日光下目视颜色无变化。0.1N 硫酸4,24,72and 144hours80摄氏度Visualwith intense light ok = no change in colour.强光下目测颜色无变化。0.1N 硫酸4,24,72and 144hoursRoom temperature室温Visual in daylight,ok=no change in colour.日光下目视颜色无变化。ATSM C724-91 等级标准:Grade 1: No attack apparent1级-没有明显腐蚀；Grade 2: Appearance of iridescence or visible stain on the exposed surface when viewed at 45 angle, but not apparent at angles less than 30.2级-于45度角观察，可观察到表面有彩虹色或可见污点，但小于30度角时，无明显腐蚀；Grade 3: A definite stain which does not blur reflected images and is visible at angles less than 30.3级-在小于30度角时污点清晰可见，但不会模糊反射图像。Grade 4: Definite stain with a gross color change or strongly iridescent surface visible at angles less than 30, and which may blur reflected images. 4级-在小于30度角时具有色泽变化并在表面
