  1. \n

    General appearance inspection shall be conducted under fluorescent lighting. Color difference judgment shall be performed under a standard light source cabinet using standard indoor lighting. The sample shall be held at approximately half an arm’s length from the eyes (about 8 inches), and each accessory shall be inspected for approximately 3\u20134 seconds.<\/span><\/p>\n<\/li>\n

  2. \n

    Dimensional measurement: Measurements shall be taken in accordance with the drawing requirements, at a sampling level of 10 pieces per batch.<\/span>
    \nA. Dimensions shall be measured using vernier calipers.<\/span>
    \nB. Assembly\/fitment areas: Measurements shall be taken per drawing requirements. If the deviation is within 0.5mm, QA\/QC shall determine, based on the situation, whether to accept or reject the lot. If the deviation exceeds 0.5mm, QA\/QC shall determine, based on the situation, whether to apply special acceptance, sorting\/selection, or rejection. This shall serve as the basis for quality control judgment.<\/span><\/p>\n<\/li>\n

  3. \n

    Special tests: Conducted at a sampling level of 10 pieces per batch.<\/span>
    \nA. High-temperature resistance test: Place the product in a forced-air constant-temperature oven. Set the temperature and time parameters to the specified test temperature and duration for the corresponding product. The product is deemed\u5408\u683c (conforming\/passing) if no cracking or breakage occurs after testing.<\/span>
    \nB. Fitment (assembly fit) test: Assemble the product with its corresponding mating components. The clearance\/gap between them shall not exceed the specified standard. Under external force application, the glass shall not exhibit noticeable wobbling or movement (to be compared with the reference sample\/master sample).<\/span>
    \nC. Imaging test: Under fluorescent lighting, the image reflected by the mirror shall not be distorted and shall remain clear (visual inspection).<\/span>
    \nD. Adhesion test: Apply 3M tape firmly onto the coated surface (press down securely). After one minute, quickly peel off the tape. There shall be no peeling or detachment of the coating.<\/span>
    \nE. Anti-fogging test:<\/span>
    \na. Freezing test: Place the anti-fog mirror in an environment alternating between -10\u00b0C and room temperature. The mirror surface shall remain continuously fog-free.<\/span>
    \nb. Hot water test: Place the anti-fog mirror approximately 50px (2 inches) above hot water at 80\u00b0C \u00b1 5\u00b0C, with the mirror surface facing downward. The mirror surface shall remain continuously fog-free.<\/span>\"\"<\/p>\n<\/li>\n
