A huge climate chamber of 30 cubic meters, with reinforced laminate flooring standing side by side in order to detect the release of harmful substances in a simulated environment; various tree species specimens are displayed together, like a small museum," The collection is made of wood materials that are common in the world. Recently, the reporter went into the testing laboratory of the National Furniture and Indoor Environmental Quality Supervision and Inspection Center (hereinafter referred to as the center) to explore the changes in the laboratory over the past decade.
As the only national quality inspection center integrating furniture and indoor environmental quality testing, the center combines traditional furniture quality inspection with the most concerned air quality inspection. Luo Xin, deputy director and senior engineer of the center, said that the center now has a furniture testing laboratory, an indoor environmental testing laboratory, a tree species identification laboratory, and a decoration and decoration materials testing laboratory. The special feature is that it can be used for the whole project inspection of furniture. It can also detect indoor environments.
“The predecessor of the center was the Beijing Wood Furniture Quality Supervision and Inspection Station established in 1982. After successfully serving the 2008 Beijing Olympic Games, it was formed in cooperation with the Beijing Municipal Product Quality Supervision and Inspection Institute.†As a working in the center 14 Years of quality inspection "veterans", Luo Wei's history of the center is like a few treasures.
The phone has become less and the quality has improved.
Ten years ago, the center had a hotline for intercommunication with consumer associations to answer consumer complaints and inquiries about the quality of furniture. Every summer, the hotline became “hot†and received almost every 5 minutes. A complaint consultation phone, busy the operator dizzy. “When the temperature rises, many families may have a taste, and the corresponding complaints and consultations will naturally increase.†In the impression of Li Jiguang, deputy director and senior engineer of the center, this summer is the summer with the least phone call in the center for 10 years. On average, there are two or three complaints and telephone calls every day, and many of them are called for consultation.
In 2001, China’s furniture industry’s first mandatory national standard GB18584-2001 “Limited Hazardous Substances in Interior Furniture and Decoration Materials†was officially promulgated. At that time, a random inspection made Luo Wei once a big question mark on the necessity and feasibility of the implementation of this standard. That was a random inspection of the furniture sold by a Beijing Furniture City Entrustment Center. The result was the release of formaldehyde, and the pass rate was less than 19%.
"I was really worried about whether this standard could be 'landed'. It is much better now, and the test pass rate is close to 90%. The unqualified products are mainly concentrated in small and medium-sized enterprises and some unknown building materials market." Luo Wei believes that this It shows that the quality of Chinese furniture has been improving. On the one hand, Beijing has been reorganizing the quality of furniture and wood-based panels, and its product quality has improved significantly. On the other hand, China has become the world's largest furniture manufacturing and exporting country, and the overall quality level has increased significantly.
The ability has become stronger and the standard has become stricter.
Walking into the center of the tree species identification laboratory, it feels like walking into a small museum of wood, each with a variety of specimens of different colors and sizes, which made a great contribution to the determination of furniture materials.
"Now the common tree species in the world can be found here, and they can all be detected and judged." Speaking of the level of the laboratory, the director of the laboratory, Sun Shudong, proudly said: "Now mahogany furniture and solid wood furniture are very popular. It is also increasing, requiring the center to give an authoritative judgment. Previous material testing of Da Vinci furniture was carried out here."
Although the tree species identification laboratory was only 8 years old, it has become one of the center's characteristics and trump cards. "This is a scientific research project of the AQSIQ that we just completed. It passed the acceptance test at the end of last month." Pointing at the computer running software, Li Jiguang told reporters that this topic is an identification operating system for tree species. During the detection process, the system can check the material of the sample, saving the time for manually reading the data for comparison, and reducing the human error.
A huge climate chamber, just put the sample inside for about 24 hours, the release of various harmful substances such as formaldehyde has the result. The largest environmental climate chamber with the largest number of countries has become another feature of the center. “These are high-tech equipment added by the center in recent years, which can detect all harmful substances.†Li Jiguang clearly remembers that when he first came to the center 10 years ago, he could only perform routine mechanical tests, quality inspections and simple There is almost no chemical analysis for the measurement of hazardous substances. Now, both heavy metals and formaldehyde, as well as VOC (volatile organic compounds) and TVOC (total volatile organic compounds) can be tested.
The improvement of detection ability is in line with the strict requirements of testing and the improvement of life life. As the leading testing institution in China, the center is also the main drafting unit for the revision and revision of many national standards, including the national standard “Hazardous substances in wood furniture for interior decoration materialsâ€. The revision of the Limited Edition and the development of the new national standard "Limits of Hazardous Substances in Upholstered Furniture Sofas" and "Limits of Hazardous Substances in Upholstered Furniture Mattresses". "The biggest feature of these standards is that the requirements are more stringent, the types of tests have also increased, and the detection methods have changed. This puts higher demands on the detection capabilities."
