When a ceramic surface becomes contaminated, the ease or difficulty of cleaning it is referred to as its "anti-fouling performance." Products that are easy to clean are considered to have good anti-fouling performance, while those that are difficult to clean have poor performance. According to the national standard GB/T 4100-2006 titled "Ceramic Tiles," there is no specific numerical requirement for anti-fouling performance. Instead, manufacturers are required to report the level of anti-fouling performance of their products to consumers. This means that the anti-fouling performance is not an enforceable standard but rather a descriptive indicator.
In reality, the anti-fouling performance of ceramic tiles plays a crucial role in daily use, especially for polished tiles, which are more prone to staining and soiling. As a result, consumers should consider the actual anti-fouling performance of the product when selecting tiles for different areas. The test method for anti-fouling performance is clearly outlined in the national standard GB/T 3810.14-2006. Based on the results, ceramic products are classified into four levels: A, B, C, and D. Class A represents the best anti-fouling performance, while Class D indicates the worst. Understanding these classifications can help buyers make more informed decisions when purchasing ceramic tiles for their homes or commercial spaces.
