Testing Dimensions for Tempered Glass Screen Protectors

Comprehensive Quality Testing Dimensions for Tempered Glass Screen Protectors

When assessing the quality of tempered glass screen protectors, the following testing dimensions are crucial to ensure performance and reliability:

1. Hardness Test

• Purpose: To evaluate scratch resistance, with a standard rating of 9H on the Mohs scale.
• Method: Use tools of varying hardness to scratch the surface and observe if any marks are left.

2. Impact Resistance Test

• Purpose: To measure the protector's ability to withstand accidental drops.
• Method: Drop a steel ball from different heights onto the glass to check for breakage.

3. Light Transmittance Test

• Purpose: To ensure the screen remains clear and bright.
• Method: Use a light transmittance meter to measure transparency, typically aiming for over 90%.

4. Water Contact Angle Test

• Purpose: To test the hydrophobic properties for anti-fingerprint and easy-clean effects.
• Method: Drop water onto the surface and measure the contact angle—the larger the angle, the better the hydrophobicity.

5. Anti-Fingerprint Test

• Purpose: To determine how well the glass resists fingerprints and oil stains.
• Method: Simulate finger touches and assess the visibility and ease of cleaning the marks.

6. Blue Light Blocking Test

• Purpose: To protect eyes by reducing harmful blue light exposure.
• Method: Use a blue light testing device to measure the level of blockage.

7. Edge Strength Test

• Purpose: To check the durability of the glass edges, especially for 2.5D and 3D curved designs.
• Method: Apply pressure or impacts to the edges to evaluate their strength.

8. Touch Sensitivity Test

• Purpose: To ensure the glass does not hinder touchscreen responsiveness.
• Method: Simulate daily touch operations to verify sensitivity and response time.

9. Thickness and Weight Test

• Purpose: To strike a balance between durability and aesthetics.
• Method: Measure the glass thickness precisely using a thickness gauge.

10. Ease of Installation Test

• Purpose: To evaluate if the glass can be installed bubble-free.
• Method: Perform installation and assess the ease of alignment and bubble removal.

11. UV Resistance Test

• Purpose: To determine the glass's ability to block harmful UV rays.
• Method: Use a UV light meter to measure UV blocking effectiveness.

12. Lamination Strength Test

• Purpose: To ensure strong adhesion between the layers, preventing delamination.
• Method: Apply force to check if the glass separates into layers.

13. Shatterproof Test

• Purpose: To ensure safety by preventing sharp shards in case of breakage.
• Method: Intentionally break the glass and observe if the fragments remain adhered together.
