The national standard for parquet and laminate flooring (impregnated paper laminated wood flooring) was implemented on August 1, 2000. The formulation, revision and implementation of hospitality standards are the two most basic work links in the standardization activities that are interrelated and mutually restrained. The intended purpose and role of standardization should be achieved through the development, revision and implementation of standards. Formulating an advanced and reasonable technical standard provides preconditions for achieving the best production order and social and economic benefits. The implementation of the standard can apply the comprehensive results of science and technology and practical experience to production. For direct productivity. The national standard for impregnated paper laminated wood flooring and parquet has been implemented for one month, which coincides with the implementation of the "Product Quality Law of the People's Republic of China", which has caused the construction of impregnated paper laminated wood flooring in China. Therefore, the introduction of national standards is bound to be It has attracted the attention and attention of foreign manufacturers that export low-laminated wood flooring to China. China's local quality supervision and administration departments will also strengthen the implementation of the two national standards for laminate flooring and solid wood composite flooring to explain a few issues of concern to everyone.
1. Article 26 of the "Product Quality Law of the People's Republic of China": Producers shall be responsible for the quality of the products produced.
Product quality should meet the following requirements:
If there are no unreasonable dangers that endanger personal and property safety, and there are national standards and industry standards that guarantee human health and personal and property safety, they shall comply with the standards:
Have the performance of the product, except for the description of the product's performance;
It conforms to the product standard indicated on the product or its packaging, and conforms to the quality status indicated by product description and physical sample.
On July 8, 2000, the 16th meeting of the Ninth NPC Standing Committee reviewed and approved the authoritative further interpretation of the provisions of the "Product Quality Law of the People's Republic of China". The three requirements put forward in Article 26 are explained as follows: "According to the provisions of the "Standardization Law of the People's Republic of China", products of safety and hygiene standards may endanger human health, personal and property safety, and therefore producers must implement Its products are required to meet the requirements of these standards.... This is also an important guarantee obligation for producers to guarantee the quality of products. The unreasonable danger mentioned here is relatively reasonable risk." "If the product quality does not meet its basic performance requirements, there is a flaw, the producer has not explained this, it should bear the responsibility for product quality. The term "瑕疵" refers to the product does not meet the requirements or general quality specifications, The situation affecting the effect of use....... For the product has been clearly stated, the producer can still sell." "When the producer indicates the standard adopted by the product on its product or on the packaging, this indicates that the producer has made a guarantee to ensure The quality and performance of the product meets the requirements of the standard: when the manufacturer indicates the quality, function, shelf life, quality level and other quality conditions of the product in the product description, this becomes a guarantee for the producer, proving that The quality of the product has reached the stated situation. Similarly, when the producer takes the quality of the physical sample, if the quality of the product produced by the producer does not meet the above explicit guarantee, it should be responsible according to law.†For both laminate flooring and parquet The quality responsibility of the producer of the product, I would like to add the following comments: the country of the two products Producers use other standards and shall make express warranties on the products or packaging, contracts or other quality documents. According to the provisions of China's "Standardization Law", the recommended standards are not enforceable. The state encourages enterprises to adopt them voluntarily, but once they decide to adopt them, they must be implemented carefully. The recommendation standard only points out to the enterprise the general direction of the quality demand of the society, and does not guarantee that users and consumers must choose this standard as the technical basis for exchange. Therefore, when companies adopt recommended standards. The recommended standards selected by the company must be adjusted in a timely manner in response to changes in market demand for product quality. Under this circumstance, enterprises should formulate enterprise standards that are stricter than national and industry standards and implement them within the enterprise to improve the market competitiveness of the products of the enterprise. Both laminate flooring and engineered wood flooring have formaldehyde release problems that are related to human health. It was originally suggested that the regulations on formaldehyde emission in the two national standards for laminate flooring and solid wood composite flooring should be mandatory. Later, the standardization management department considered adding mandatory provisions to the recommended standards, which was difficult and not implemented. Approved by the standardization management department, the mandatory standard for the emission of formaldehyde from wood-based panel products is being formulated, and is responsible for the quality supervision and inspection center of the board. Laminate flooring and engineered wood flooring have been one of the best products of formaldehyde emission in China's wood-based panel products for many years. However, in the recent period, we have repeatedly tested samples of laminate flooring larger than 40mg/100g (perforation method). In the Beijing market, "reinforced wood flooring" with a surface wear resistance of only 50 or 100 turns has been found many times. The market of laminate flooring has been shoddy and has a tendency to develop and expand. It is hoped to arouse the vigilance of unemployed.
Second, the national standards for impregnated paper laminated wood flooring and solid wood composite flooring are first formulated, and there will be some imperfections. In the implementation process, such problems will be found and will be corrected and improved when the standards are revised later. Earlier we have stated that the development and implementation of standards is to apply the combined results of science and technology and practical experience to production and to direct productivity. Whether the standards are advanced and reasonable plays an important role in the development of the entire industry. The implementation of the two standards has received widespread attention throughout the industry, and has also caused great impact in society. Although the formulation of these two standards is short, the preparation work has been done in a solid and detailed manner. The analysis of technical data at home and abroad is more comprehensive and objective. The collection and verification work of physical samples at home and abroad have greatly exceeded the standards of other wood-based panel products. The scale of the formulation was made and opinions were widely sought at the standard validation meeting. Therefore, we believe that these two standards objectively reflect the overall level of the industry, compared with similar foreign products, the same level of cards, compared with similar products abroad, the important quality indicators have reached the advanced level of similar foreign products. Here are a few quality inspections (working) issues that I hope will draw attention to everyone:
1. The moisture content of the laminate flooring. Due to China's vast territory and large climate differences, the variation in water content is also large. Most of the time in Beijing, the moisture content of laminate flooring is usually below 5%. However, in mid-August and late August, it is rainy season. The moisture content of laminate flooring is mostly 5-7%, which is completely normal. Phenomenon, but individual companies have placed water content below 5% in contracts, which has caused great difficulties for themselves. I hope everyone will pay attention. In fact, the emergence of such problems is irrelevant.
2. The problem of surface wear resistance of laminate flooring. The instruments for measuring the wear resistance number at home and abroad are the same, and the technical parameters are also the same. If different inspection organizations have different detection results, the reason may be two; one is that the determination of the end point is inconsistent, and the second is the use. Different types of sandpaper strips. Of course, there are also articles that the wear test is actually a destructive test. The probability of initial damage is different. The test pieces are different, so the reproducibility is poor. According to the results of our inspection statistics, the test of the wear resistance of the surface of the laminate flooring is still relatively reproducible. Therefore, when there is a large difference in wear resistance and sensitivity, the main reason should be whether the determination of the flaw is inconsistent or the use of different types of sandpaper strips, and please pay attention to the inspection of the sandpaper strip itself to ensure the use of qualified sandpaper. Article. 3. The specification of the static bending strength index of the laminate flooring is determined by the results of a large number of tests. Usually, there is no problem. Recently, individual samples appear, and other quality indicators are good, but the static bending strength does not meet the requirements. The possible reason is to ignore the quality of the balance paper. It is clear to everyone that the balance paper produces the greatest stress when determining the static bending strength. If the balance paper quality is poor, it will affect the inspection results.
4, the immersion peeling test of solid wood composite floor requires water temperature of 70oC ± 3oC, the quality requirements are very high. Compared with foreign similar product standards, it is also the most demanding. This is very clear to the enterprises that produce adhesives. It is hoped that the manufacturers of solid wood composite flooring will also pay full attention. We proposed several options at the standard validation meeting, and finally chose the test method that is currently implemented.
5. The problem of formaldehyde emission. According to the determination of a large number of physical samples, the starting point of the quality level of the domestic laminate flooring and solid wood composite flooring is very high, and the formaldehyde emission can fully meet the specified index requirements. However, due to the intensified market competition, a number of smaller laminate flooring factories have emerged. In order to reduce costs, they use medium-density fiberboard with a high formaldehyde emission as the floor substrate, hoping to attract the attention of the whole industry. We are formulating a mandatory formaldehyde emission standard for wood-based panels, which will be legally stopped after formal implementation.
6. Two standard appearance quality inspection specifications Dimensional inspection adopts a sub-sampling scheme, which considers that the overall quality level of these two products is higher than other wood-based panel products, in order to reduce the number of samples and reduce the inspection cost. Adopted. Although a sub-sampling scheme is used, it is usually possible to make a judgment as long as the first sampling is performed.
7. Both standards stipulate that manufacturers must provide instructions for the installation and use of Chinese. This is actually a form of improving the competitiveness of enterprises and self-protection of enterprises, and hopes to fully understand them.
