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, laminated glass and insulated glass production enterprises have been forced to undergo product certification. Enterprises must screen print or paste the 3C mark on the body of the products they sell, or add the 3C mark on their smallest outer packaging and accompanying documents (such as certificates of conformity). When selecting a product, the first thing to check is whether there is a 3C mark, and based on the company information, factory number, or product certification certificate, check whether the purchased product is within the scope of the company's mandatory certification and whether the certification certificate is valid through the internet.
2. Check the appearance and quality. Check the appearance quality of the product, the laminated glass should not have cracks or delamination; There should be no wrinkles or stripes in the middle layer; The length or width of the edge should not exceed the thickness of the glass; Scratches and abrasions should not affect use; The dot and linear defects such as bubbles, impurities, scratches, etc. in the middle layer should not affect its use.
