It is difficult to meet the standards for acceptance of ceramic tile paving

Qualified ceramic tiles, a professional paving team, and the paving process is guaranteed to be up to standard. Everything looks perfect! Mr. Wang started preparing for paving, but he can’t guarantee that the final project quality inspection will pass? Hear what the decoration company personnel said , Mr. Wang was puzzled: "Qualified product + qualified process ≠ qualified project", Why?

In the event that the qualified product will also cause the project to be unqualified

After consideration, the owner Mr. Wang , he decided to tile his home. After buying the ceramic tiles and handing them over to the decoration company, the staff of the decoration company told him that in order to ensure the quality of the project, they had the company's experienced bricklayers test the ceramic tiles before paving and found that there might be a problem with the warpage of the ceramic tiles. If the paving continues under this condition, even if the construction procedures and techniques of the decoration company's construction personnel are qualified, the final project quality may not be up to standard.

Mr. Wang found a ceramic tile agent, who produced a quality inspection report for the ceramic tiles. According to national regulations, these ceramic tiles were qualified, including the warpage problem. Mr. Wang is confused. If you combine qualified products with qualified workmanship, you will not get qualified projects?

The truth is that differences in industry standards lead to problems

Since ceramic tiles are in compliance with national Standard, why does it fail to pass when laid on the ground? It turns out that the problem lies in the difference between the two standards of "tile warpage" and "floor engineering flatness".

Depending on the size of the tiles, the warpage of the tiles will also change accordingly. Taking 800mm×800mm ceramic tiles as an example, the national standard determines that the warpage of ceramic tiles should be between plus and minus 1 mm; while the acceptance standard for the flatness of floor projects is 0.3 mm. In this way, there will be a phenomenon where the product is qualified but not qualified after paving.

The reporter interviewed industry insiders about this. Dong Jianjun, general manager of European and American Ceramics, said: "This kind of contradiction between standards does exist. Now many big brands have put forward higher standards for brand products in order to improve the quality of their products. Standards - enterprise standards, effectively avoid such problems."

Qin Jian, an engineer at the Shaanxi Provincial Interior Decoration Engineering Quality Supervision and Inspection Station, said: "We generally try to persuade sellers to exchange products." Longfa. Decoration general manager Li Chi said: "When encountering this kind of situation, home decoration companies are also in a dilemma. In addition to trying to help customers check the quality of bricks and actively contact sellers for replacement, for some products with less serious conditions, try to make them The paving workers laid these bricks in inconspicuous places such as corners, sofas, and beds.”

The industry improves product quality to avoid conflicts

Shaanxi Province Decoration and Decoration Materials Quality Supervision and Inspection. Yang Guijian, the station director, said: "Currently, the country has very clear regulations on the quality standards of ceramic tiles. The warpage degree is also detailed based on the size of the bricks. When conducting material testing, we will strictly follow the national standards."

Pang Rui, director of the Shaanxi Provincial Interior Decoration Engineering Quality Supervision and Inspection Station, said: "Generally, the acceptance standard for the ground is to take at least three points in a natural room, and each point is measured in units of two meters. The flatness of the ground is tested, and the warpage of three points is deemed to be qualified."

Yang Guijian said: "Before the new standards were introduced, in order to avoid such phenomena, the ground was deemed to be qualified. It is very necessary to conduct strict inspection of products so that defective products can be returned or replaced in a timely manner or the paving position can be adjusted. ”

The rapid development of the industry has brought more material and visual enjoyment to consumers. At the same time, there are also some hidden problems: the threshold for employment is too low, various normative standards are not in place, or the development of the industry seriously lags behind. Industry insiders called on relevant departments to adjust industry-related standards as soon as possible to avoid similar phenomena from happening again.
