Wood floor already has a national market, why so many false propaganda? parties reactions have indicated that national testing standards also exist many vulnerabilities.
Vulnerability detection device does not have an explicit provision
Flooring products quality differences are so obvious, is of course a few wood flooring manufacturer in the manufacture of fake and shoddy products, disrupting the market factors also continues to show a row national standards in the slit. In testing equipment, world unity with Taber-type device detection of flooring, and revolution in China, but only "in the national standards or equivalent test equipment".
Vulnerability II substrate and formaldehyde malposition
On product detects the content of formaldehyde also exist such a problem. Clearly labeled substrate formaldehyde content as qualifying, but has been tested and found to have exceeded, this product is often appears flooring. It is understood that national standards for material requirement is 30 mg of formaldehyde, and thus produce the product is not provided for formaldehyde emission as standard 9mg/L; floor to this standard must choose the formaldehyde content 20 mg of base material. This standard for floor production enterprises out of the problem. On the one hand the substrate detection is qualified, on the other hand terminal product testing.
Vulnerability testing method three expansive biased
Thickness swelling reflects the performance of water resistant substrate. As the floor of the substrate, its water resistance should be more furniture, this indicator is very important. Existing national standards of laminated flooring in the laminated flooring thickness swelling of the test method takes a 50 x 50 (mm) of the specimen, in 20 ¡æ water soaking for 24 hours, the specimen thickness of the center point changes before and after soaking to calculate its thickness swelling. In fact, the moisture from laminated flooring edge immersed in plate moves much slower, often at the edge of the specimen is very troublesome expansion, and the Center does not change.
