1 Visual Quality 视检

1.1 Visual inspection should be carried out under below condition：

检查应该在下列环境下进行：

1.1.1 Illumination: D65 light source -CIE Standard illuminant ISO10526:1999 (E)；

视检应该在D65光源条件下进行；

1.1.2 Viewing time for each part: 10 seconds；

每个部品的检查时间：10秒；

1.1.3 Inspection distance from products: 30cm；

检查产品的距离：30cm；

1.2 Painted surfaces quality according Class I；

对于喷涂区域，检查标准按照Class I标准执行

Other surfaces according Class III；

其它区域检查标准按照Class III标准执行：

Class I :Surfaces which are frequently visible in normal use but require good visual quality .

等级I：对于客户在正常使用下经常看的到的表面且需要较好的外观品质的标准，例如：镜片、手机外壳等。

Class III : Inner Surfaces which are never visible to customer in final product and do not require good visual quality.

等级三: 对于在客户的成品中不可见的内部面、外观品质要求不高的标准。

1.3 The minimum painting area ( see above picture)

喷涂区域(详见下图)；

2 Thickness measurement

2.1 The measurement location is as below(Points marked with arrows)；

测量位置如下图所示（用箭头标注的点）；

2.2 The standard for painting thicknesses of Sheet-1 refer to customer’s otherwised requirement

Sheet-1的喷涂厚度标准参照客户另外的要求；

3.Thermal Shock Test温度冲击测试

a) Low Tem.:-40℃±2℃;high Tem.:85℃±2℃ ,2hour/2hour per each condition,transfer time:15s (lower than 3min) .total cycle: 5cycles(totally 20hours)；

-40° / +85°C 各2小时，此为一个循环，共5个循环，（20小时）温度切换时间15s(不大于3分钟)；。

b) No visiable decomposition, No mechanical decomposition,Electrical value<1ohm. Adhesion test classification:0-1grade；

不允许有任何外观不良，如变形，白化，变色；

4. UV Radiation endurance 抗紫外线老化测试

a)Test requirement: Put the parts into QUV/Se Accelerate Aging Tester（Amercian）, The test

consists of 12 cycles, each cycle being 8 h long, total test period is then 96 hours. One cycle consists of 4 hours UV exposure (UV-A, 340 nm, 60 ︒C, ∆E-value ≤ 0.7) and then 4 hours moisture exposure (50 ︒C).
