Nine standards for film acceptance

Core topic: This document aims to summarize and explain the key standards and considerations for the quality inspection of car film after the car film service is completed. These standards cover multiple dimensions from appearance integrity to functionality and safety to ensure that customers receive high-quality film services.

Main content and key points:

1. No Light Leakage

• Core requirement: No light leakage is allowed on the glass after film application.
• Specific rules: No light can leak from both sides of the side window glass.
• "Light leakage is allowed at the edge of the secondary window glass, but the maximum distance shall not exceed 1mm."
• "When applying to the front and rear bumpers, the maximum distance between the film and the black ceramic point on the window glass should not exceed 2mm."
• Observation method: "Observe from the glass where the film is applied and the adhesive strip where the window film is applied, and the left and right sides of the glass."

1. Appropriate Size

• Core requirement: The film size must perfectly match the glass.
• Specific rules: "The upper film of the side window is cut straight, and there should be no light leakage when it reaches the top." (This point overlaps with the light leakage standard, but emphasizes the accuracy of cutting)

1. Correct Material

• Core requirement: Suitable and relatively high-quality membranes selected according to customer needs must be used.
• Importance: Ensure that the film application service meets the customer's initial selection and expectations.

1. No Bubbles

• Core requirement: No blisters or bubbles after applying the film.
• Specific rules: "There should be no water bubbles or air bubbles on the glass after the film is applied (observe from the left and right sides of the glass)" (the observation method is repeatedly emphasized)

1. No Scratches

• Core requirements: There should be no new scratches on the front, back and related parts of the film.
• Specific rules: "There must be no new scratches on the glass where the film is applied and the adhesive strips where the film is applied to the windows." "There must be no new scratches on the adhesive strips on the side windows."

1. No Creases

• Core requirement: There should be no obvious creases on the glass film after application.
• Specific rules: "The number of creases on the front windshield shall not exceed 1 (including 1)."
• "The rear windshield has no more than 1 crease (including 1)."
• Importance: It clarifies the upper limit of the number of creases that are acceptable on the front and rear windshields, but emphasizes that "obvious creases" are not acceptable.

1. No Dirt Spots

• Core requirement: The glass surface should be kept clean after film application.
• Specific rules: "Check from 1 meter away from the car. The number of dust spots within 10 square centimeters after the glass film is applied cannot exceed 10."
• Acceptance distance: emphasizes the acceptance perspective of "checking at a distance of 1 meter from the vehicle".

1. No Ghosting/Haze

• Core requirement: The film should not have any virtual prints that affect vision.
• Specific rules: "Metallic imprints may appear when baking the film, but they are usually located at the edge (within 15 cm from the edge) and are not allowed in the middle."
• Acceptable range: The acceptable edge positions of virtual printing are clearly defined, and it is strictly prohibited to appear in the middle position.

1. No Risk of Cracking

• Core requirement: The glass should not break due to construction problems during or after the film application process.
• Division of liability: "Due to technical level and glass defects, there is a possibility of glass cracking. If glass cracking occurs during installation or within 24 hours after installation, the construction store will be responsible for compensation."
• Important note: The responsibility for glass breakage and the compensation period (within 24 hours) are clearly defined.
