Inspection Report

The report shows the situation at the inspection site. Check and verify that the goods meet the requirements of size, weight, packing and workmanship according to the information provided by customer. Work is good, function test is normal.

Floor acceptance criteria

1, See if the color of the floor is consistent. If the color difference is too large, directly affect the beauty, you can find the swap. Whether the color is consistent, there is almost no color difference, it depends on the pattern of the floor surface no the same. If the pattern is similar, it may be a process wood floor, rather than the so-called.
The flooring of the precious wood species. Now some flooring material suppliers, the use of general wood material .The floor, but on the surface of a layer of rare wood species of wood veneer to shoddy, said to be used to moisture-proof, in fact,for fear of being seen that the pattern on the back does not match the pattern on the front.

2, See whether the floor has a sound, acceptance on the floor. Walk up and down, step more, so especially near the wall and door parts should pay more attention to acceptance, found that there is a sound part, to repeat walking.
Determine the exact location of the sound and mark it. In this case, you can ask for removal and resurfacing. There are the part of the sound is that the construction personnel in the construction process, the operation is not standardized and the use of materials is not qualified. The non-standard operation is mainly reflected in the unstable fixing of the keel; The unqualified materials are mainly reflected in.The keel has not been dried. Some decoration construction units use undried keel construction on the surface.
There are drying marks. It’s not dry. A keel with a high moisture content, formed during the natural drying of wood the volume will shrink, causing loosening.

3. Check whether the floor is deformed and warped. The method of acceptance is to use a 2-meter long ruler and lean on it.On the floor, the flatness should not be greater than 3 mm. Take a few more measurements, if the pass rate is above 80%.It is regarded as qualified, otherwise, it is not qualified. Sometimes we find the floor partially arching: if it is a solid wood floor, which is because the floor is too tight or too dry (too low water content); if it’s laminate flooring. That means poor flooring. Therefore, the floor arch is a serious quality problem.

At present, the main standards related to infant and children’s clothing products are:

National mandatory standards GB18401-2003 “National Textile Safety Technology and Code” and GB5296.4-1998 “Consumer goods Instructions for the use of textiles and clothing”;

Product standards (such as FZ/T81003-2003 “Children’s clothing, student clothing”, FZ/T 73007-2002 “Knitted sportswear”, FZ/T 73008-2002 “Knitted T-shirt”, FZ/T 73021-2004 “Knitted student clothing”, FZ/T 81004-2003 “Dresses, skirt covers” and FZ/T 73025-2006 “Baby Knitwear”, etc.

The main testing items involved in infant clothing are:

Formaldehyde content, decomposable aromatic amines, pH value, odor, color fastness to water, color fastness to friction, color fastness to perspiration, color fastness to saliva, labeling, fiber content and physical properties testing of related products.

What needs to be concerned about is that the FZ/T 81014-2008 “baby clothing” product standard will be officially implemented from October 1, 2008. This standard is the first product standard specifically designed for the safety of infants and young children (aged 24 months and less). The standard clearly stipulates that all provisions involving the safety of clothing are mandatory, at that time, heavy metal residues exceed the standard, safety design and other aspects of unqualified baby clothing will not be sold. Some quantitative indicators are clearly specified in the standard, such as formaldehyde content shall not exceed 20 mg/kg, arsenic content shall not exceed 0.2 mg/kg and so on. The standard also requires that the addition of decomposed aromatic amine dyes is prohibited in infant clothing, and there should be no odor, and the pH value is limited to 4.0~7.5. In addition, baby clothing must be marked “do not dry clean” on the label, because the dry cleaning agent may contain substances that irritate the baby’s skin. At the same time, the standard also regulates the design of infant clothing.Clothing inspection standards
