1. Inspection of glass panels. The appearance quality is mainly checked for flatness, observing for quality defects such as bubbles, inclusions, scratches, lines, and fog spots. Glass with such defects will deform during use, reducing its transparency, mechanical strength, and thermal stability. Therefore, it is not suitable for use in engineering. As glass is a transparent object, its quality can be easily distinguished by visual inspection during selection.
2. Inspection of glass processing products. In addition to testing according to the requirements of flat glass, its processing quality should also be inspected to ensure that the specifications, dimensions, processing accuracy, and pattern clarity meet the requirements. At the same time, there should be no defects at the edges
