1. Check the logo and certificate, and purchase products from legitimate manufacturers with the 3C certification logo. Since the implementation of safety glass product certification in 2003, most tempered glass production enterprises in China have undergone product certification. It is necessary for enterprises to screen print or affix the 3C mark on the body of the products they sell, and perhaps add the 3C mark on their smallest outer packaging and accompanying documents (such as certificates of conformity). When selecting products, the first thing to check is whether there is a 3C mark, and based on the enterprise information, factory number, or product certification certificate, the purchased product should be checked online to ensure that it is within the scope of mandatory certification by the enterprise, and whether the certification certificate is valid.

2. Due to the lack of significant differences in appearance between tempered glass and regular glass, some unscrupulous merchants use regular glass with 3C logos printed on it to replace tempered glass for sale. Consumers can identify whether a product is ordinary glass through polarized light survey. If there are no colorful stripes or spots found through polarized light survey, it indicates that the product is ordinary glass. However, if colorful stripes or spots are found during the survey, it can only indicate that the product has undergone tempering treatment and cannot clarify whether the tempering quality is up to standard. Polarized light can be found in camera lenses or sunglasses, so pay attention to adjusting the light source during investigation.

3. Pay attention to investigating the appearance of tempered full glass. Tempered glass should have no defects such as bursting edges, cracks, missing corners, and no dense or scratched surfaces that affect product use, with good flatness.

4. During use, external impact should be avoided as much as possible, especially at the edges and corners of the glass. When cleaning glass, be careful not to scratch, scrape, or grind the surface of the glass to avoid affecting its appearance.

5. Self explosion is a characteristic of tempered glass and is inevitable. The industry generally believes that the self explosion rate is 0.3%. In order to prevent fragments from splashing and causing harm to the human body during the self explosion of tempered glass, it is recommended to add a layer of explosion-proof film on the tempered glass during use.
