It revolves vertically for 30° to both the right and left. Examine for 5 to 10 seconds. 1.4 If unspecified, the surrounding conditions are (by default): 20±5℃,65±10 %RH; 1.5 Examination tools: gloves, special comparison template, plug gauge, vernier caliper, magnifying glass, microscopic measurement devices, film, comparison color plate, defect card, etc. 2. Definition for appearance surface levels: Level A appearance surface: Under normal use conditions, the product surface that is always touched by the user, or the portions that can be directly perceived by the naked eye. As shown in the diagram below, Level A appearance surface can be further divided into four categories: A1 surface: When the LCD module is closed, the LCD back cover surface (where the logo is situated) that can be seen by the user; A2 surface: When the LCD module is open to 90 degrees, the surface where the LCD screen is situated (including the LCD screen surface and the four sides of the LCD cover); A3 surface: When the LCD module is open to 90 degrees, the surface where the keyboard and mouse pad are situated in a normal use state; A4 surface: When the LCD module is closed, the front side surface that the user faces; Level B appearance surface: When the LCD module is closed, the right and left side surfaces that the user faces; Level C appearance surface: When the LCD module is closed, the side surface opposite to the A4 surface (the back of the host computer), as well as the bottom side surface of the host computer; Level D appearance surface: When the host computer is placed or used normally, the inside area of the host computer. Front surface, top surface: When the LCD is closed, the top surface and the surface that faces the user; when the upper lid is open, the LCD surface and the keyboard surface, totaling four surfaces; As shown in the figure below: Felt scratches: Any scratch that can be seen from any angle or can be felt by a finger touch sliding through. Unfelt scratches: Any scratch that can be seen only from a certain angle, or cannot be felt by a finger touch sliding through. 3.
