A sample-check on float glass products

Post Time:Oct 10,2008Classify:Industry NewsView:391

In order to guarantee the quality of decorating materials, protect the legitimate rights and interests of consumers and promote the healthy development of glass industry, General Administration of Quality Supervision, Inspection and Quarantine of the People’s Republic of China (AQSIQ) carried out a sample-check on quality supervision of float glass products. In the process, about 49 products (excluding exports) of 49 companies from Tianjin, Hebei, Inner Mongolia, Jiangsu, Zhejiang, Anhui, Shandong and other 12 provinces were checked and 84.6% of them were qualified.

According to the mandatory national standard of GB11614-1999 for float glass and the recommended standard of GB/T18701-2002 for tinted glass, AQSIQ tested 10 performances of float glass products, including optical distortion, thickness, flexibility, surface crack, and visible light transmittance. Products of large and high-market share companies were much better and all passed the test.

The main problems in sample-check:

1. Unqualified optical distortion. Some auto float glass products have lower optical distortion than 60°, which is required for building float glass.

2. Unqualified thickness. Thickness of some products is beyond the requirement of the national standard that is 5mm±0.2mm.

As for those problems, AQSIQ has obliged the local quality supervision and inspection centers to deal with the unqualified companies according to the law, and to publicize those high-quality companies in the sample-check. AQSIQ will continue to supervise the quality of float glass and promote the quality level of the industry.
