A wooden door comparison test by the China Consumers Association has made the well-known wooden door brands such as Longjia, Spring and Yiyuan on the “black list†of unqualified quality. According to the wooden door association, these wooden doors are not unqualified, but because the applicable standards are lagging behind, the wooden door industry generally uses the industry standards promulgated by the National Development and Reform Commission in 2006; the China Consumers Association believes that the industry issued by the Ministry of Construction in 2000 The standard has not been invalidated, and it can also be used as a basis for testing. According to this standard, some indicators are not up to standard and cannot be considered as qualified products. Therefore, some enterprises are called Qu: We spend more than 20,000 yuan a year to take the initiative to check the quality, in order to ensure the quality of the product, where to know the results of the two standards will be inconsistent. Due to the national standard “difficult to produceâ€, many industry standards are parallel and “fighting†each other, which makes the wooden door enterprises fall into the embarrassing situation of how to choose standards.
Confused: "Qualified" products were found "unqualified"
Our products are all qualified by the national authorities, and all have qualified inspection reports. How can we fail? "When the China Consumers Association's comparison test results on wooden doors were reported by the media, and listed brands such as Dragon, Spring, and Yiyuan were not up to standard on indicators such as "impregnation and peeling", they were considered as "unqualified" products. Relevant companies that have boarded the quality "black list" have expressed surprise and confusion.
Time passed to a month ago. On December 10, 2010, the China Consumers Association released the results of the comparison of wooden doors produced by 21 companies. Most of the companies were good at formaldehyde and sandbag impacts involving personal and property safety, but the surface bonding strength was good. There are differences between the brands on the three indicators of impregnation, peeling and water content. Especially on the index of “impregnation and peelingâ€, five brands including Longjia, Spring and Yiyuan exceeded the standard value by more than twice. As the media competed to report, these “involved†brands suffered an unprecedented quality crisis.
The Chinese Consumers Association seems to be a routine comparison test, which has caused an uproar in the wooden door industry. An important factor is that these brands that are “compared†to the problem of non-conformity are more famous. From the point of view of the testing procedures, it is completely fair and fair: the products are purchased from the Beijing market, and the commissioned testing unit is the authoritative national quality control and inspection center for wood-based panels and wood and bamboo products. The standard adopted is the current national mandatory standard. "GB18580-2001 indoor decoration decoration materials, formaldehyde release in wood-based panels and their products" and industry recommended standards "JG/T122-2000 construction wooden doors, wooden windows", the former test samples of formaldehyde emission, the latter test samples Indicators such as moisture content, immersion peeling, surface bonding strength and sandbag impact.
"To enter the brand store sales, there is no certificate issued by the national authority, it is impossible." A wooden door manufacturer told reporters. The reporter found that the current inspection certificate provided by the wooden door enterprise to the store is mainly issued by the National Building Materials Testing Center. It is also a national-level quality inspection agency. Can the National Wood-based Panel and Wood Bamboo Products Quality Supervision and Inspection Center and the National Building Materials Testing Center come to different conclusions? From the perspective of the company, in the face of one test, the result of another test failure is not only a surprise and confusion, but also aggrieved: we do not spend less on testing fees, how do we know which test center issued a report is valid?
Puzzle: Two standards make companies choose to be at a loss
According to industry insiders, both the National Wood-based Panel and Wood Bamboo Products Quality Supervision and Inspection Center and the National Building Materials Testing Center are national authoritative quality inspection agencies, and the test reports issued are legally effective and authoritative. Inconsistent test results, the key point is that the applicable standards are different.
In addition to the release of formaldehyde according to the same industry standards, most of the inspections of wooden doors for other indicators are based on the “WB/T1024-2006 wooden door†standard issued by the National Development and Reform Commission in 2006. The tested items include allowable deviation and residual joints. Limits, veneers and paint surface appearance, moisture content, etc., and the standards adopted by the China Consumers Association for comparative testing are JG/T122-2000 construction wooden doors and wooden windows issued by the Ministry of Construction in 2000. Including moisture content, dip peeling, surface bonding strength and sandbag impact.
A slight comparison reveals that, except for the “water contentâ€, the items tested by the two industry standards are basically the same. A wooden door business executive told reporters that it is quite easy to meet the industry standard requirements in 2006. As long as the used plates are well dried and there is no large deviation in the appearance of the production, there will be no major problems. On the contrary, the industry standards in 2000 are subject to destructive tests, and the relevant indicators are more difficult to achieve. For example, the indicator of “dip-peeling†requires the sample to be immersed in hot water for several hours before being placed in high-temperature dry air. , to see the extent of its peeling. If the peel length on each side of the sample exceeds 25 mm, it is considered to be substandard. Such a product is easy to open in the case of moisture. This is also the reason why some inferior wooden doors have used the phenomenon of “peeling†on the surface after a few years.
“As a company that wants to be a brand, we attach great importance to product quality. In addition to sampling inspections by industry associations, we take samples from the production line several times a year and send them to the National Building Materials Testing Center for testing, for fear that the products will go wrong.†The boss of the wooden door manufacturer told the reporter that the annual inspection fee for the product that was sent for inspection alone would cost more than 20,000 yuan. It is precisely because each product testing report issued by the National Building Materials Testing Center is qualified that these companies are proud of their own products and believe that their products will not have any quality problems. I did not expect the China Consumers Association to entrust the National Wood-based Panel and Wood Bamboo Products Quality Supervision and Inspection Center to test according to the "JG/T122-2000 Construction Wooden Doors and Wooden Windows", which made the five companies "plant" on the "impregnation and stripping" item. It is.
Since the wooden door industry standard released in 2006 does not have the index of “impregnation and stripping†at all, some enterprises have not paid much attention to the control of this indicator. "We think that the recently issued standard is the most authoritative standard. Do you know that there is still an old standard to implement? Should we choose one of the standards, or should we test the product according to two standards? We pay not only tens of thousands The yuan detection fee, but we have no choice in the choice!" A wooden door CEO on the "black list" talked about this matter is a bit sad.
Appeal: Wooden door enterprises expect national standards to be introduced as soon as possible
According to statistics, in 2010, the total output value of China's wooden doors has exceeded 70 billion yuan, and the number of industrialized production enterprises has exceeded 5,000. It has developed into an industry that cannot be ignored. In order to ensure the healthy and stable development of the wooden door industry, the China Wood and Wood Products Circulation Association has established a wooden door professional committee, and the China Forest Products Industry Association is also preparing to establish a wooden door branch. The birth of industry associations promoted the development of the industry, and also allowed the wooden door enterprises to find the "family". Under the leadership of the Wood Door Association, the “National Wooden Door Product Quality and After-sales Service Double Commitment Integrity Declaration†was launched in the industry for three consecutive years, and the “Top 30†enterprises of CTC wooden door product quality and health certification were evaluated. What is striking is that the brands such as Longjia and Yiyuan, which have been listed on the “black list†for “immersion and strippingâ€, are the “30 strong†brands.
The industry standard that the Wood Door Association recommends is “WB/T1024-2006 Wooden Doorâ€, and the inspection organization of the commissioned product is the National Building Materials Testing Center. Regarding the criteria for selection, Zhang Dezhi, deputy director of the Consumer Guidance Department of the China Consumers Association, believes that as long as it is an industry standard promulgated by the state authority that has not been declared invalid, it can be used. Lu Bin, director of the National Quality Supervision and Inspection Center for Wood-based Panels and Wood Products, believes that the standards on which the testing institutions are based are determined by the entrusting unit, who are only responsible for issuing fair test results in accordance with the specified standards. Although some people think that since the two standards of "WB/T1024-2006 wooden door" and "JG/T122-2000 construction wooden door, wooden window" exist, wooden door enterprises should meet the requirements of these two standards, but industry experts said These two standards are only industry recommendation standards, which can really solve the problem of standard "fighting", and we must expect the official introduction of national standards.
Where are the national standards for the wooden door industry? As early as 2007, under the appeal of the wooden door industry, the Ministry of Housing and Urban-Rural Development began to establish a national standard for wooden doors and windows. Nearly four years have passed. In a long-awaited call, this national standard is still “difficult to produceâ€. .
On September 26, 2010, the review of the National Standard for Wooden Doors and Windows was held for an expert review meeting. At that time, it was officially announced at the beginning of this year. The wooden door industry is looking forward to it. It is still unknown when the National Standard for Wooden Doors and Windows will really reveal the true colors of the mountains. This includes the national standards for the production, installation and consumption of wooden doors. It will completely break the chaotic situation that many industry standards are parallel and enterprises cannot choose. It will also bring new opportunities for the improvement of quality in wooden doors. Under the umbrella of national standards, enterprises can no longer take the standard to say things, "the standard of whether the wooden door is qualified or not depends on what standard is appropriate" will not break.
