"Our products are all qualified by the national authority, and all have qualified inspection reports. How can they fail?" When the results of a comparative test on wooden doors by the Chinese Consumers Association were reported by the media, they listed Dragon Armor, When brands such as Spring and Yiyuan did not meet the standards in indicators such as "impregnation and stripping" and were considered "substandard" products, related companies on the "black list" of quality expressed surprise and confusion.

Time passed to a month ago. On December 10, 2010, the China Consumers Association released the results of a comparative test of wooden doors produced by 21 companies. Most companies are generally very good in terms of formaldehyde, sandbag impact and other items related to personal and property safety, but the surface bonding strength There are differences between brands in the three indicators of dipping, peeling and moisture content. Especially in the index of "dipping and peeling", the five brands of Longjia, Chuntian, and Yiyuan have exceeded the standard value by more than twice. With the media rushing to report, these "involved" brands have encountered an unprecedented quality crisis.

The China Consumers Association seems to be nothing more than a routine comparative experiment, which has caused a great uproar in the wooden door industry. An important factor is that these brands that have been "compared" with substandard indicators are relatively well-known. 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 Supervision and Inspection Center for Wood-based Panels and Wood and Bamboo Products. The standards adopted are the current national mandatory standards. "GB 18580-2001 indoor decoration materials, wood-based panels and products of formaldehyde emission limit" and industry recommended standards "JG/T 122-2000 building wooden doors, wooden windows", the former tests the formaldehyde emission of samples, the latter tests The sample's moisture content, immersion peeling, surface bonding strength and sandbag impact and other indicators.

"It is impossible to enter brand stores without a certificate issued by a national authority." A person in charge of a wooden door manufacturer told reporters. The reporter found that the current inspection certificates provided by wooden door companies to stores are mainly issued by the National Building Materials Testing Center. It is also a national-level quality inspection agency. Will the National Wood-based Panels and Wood and Bamboo Products Quality Supervision and Inspection Center and the National Building Materials Testing Center come to completely different conclusions? From the perspective of the enterprise, facing one test passing another test The unqualified result is not only surprise and confusion, but also grievance: We did not spend less on testing fees. How do we know which testing center issued the report to be effective?
