所有外觀品質的檢驗環境亮度(白色燈管或自然光源)條件為 500- 800Lux。
All appearance quality shall be inspected with the lighting condition as 500~800Lux
(natural lighting or white fluorescent light).
1.1.2 目標或被觀察物的位置與目視距離
Inspection angle and distance to object or target
所有目標或被觀察物都要放置在投射的光源下檢測，其目視檢測的角度與距離是根據表
面位置等級加以區分。在所有檢測中，光源儘量避免其產品或零件對檢測人員眼睛造成
反射干擾。
All part inspection must be done under direct overhead lighting. Viewing angle and
distance are dependent on surface classification. In all cases, parts must be held in
such that the light reflection does not disturb the inspector's eye.
