Recently, in the furniture industry, the term "mechanical properties" has heated up. Not long ago, the General Administration of Quality Supervision, Inspection and Quarantine and the National Standards Committee approved the publication of 35 national standards, including six series of furniture mechanical performance test standards, involving the strength and durability of furniture such as tables, chairs, cabinets, single-layer beds, etc. And stability will be implemented in May 2014. The term “mechanical performance†has attracted the attention of the industry and the society before. It dates back to the “quality door†event of furniture in early 2010. At that time, some industry strength products were sent to the state to supervise and check the black list, which led to the discussion of national standards in the industry. question. The mechanical properties of the furniture were "amplified" twice under the spotlight, all due to the standard. These two incidents also corresponded to the two versions of the national standard GB/T10357 "Furniture Mechanical Performance Test": 1989 and 2013 editions. "With the changes in people's consumption habits, furniture has not been used for 20 or 30 years, as in the case of panel furniture, it will be replaced in seven or eight years, so national standards should also be adapted to the needs of industry development, and timely revisions and updates. "This represents part of the view of the 2010 "Quality Door" event in furniture. It is considered that the individual indicators of GB/T10357 are too strict and do not conform to the trend of fashion. When the “fast fashion†label is pasted into the traditional furniture industry, the mechanical properties such as stability, strength and durability that were originally valued are no longer important. the answer is negative. But then again, this explains to some extent the necessity of revision of some technical indicators of GB/T10357. "It is not required to be improved, and it is more suitable for the requirements of various cabinets." Luo Jufen, the chief drafter of the standard and secretary general of the National Furniture Standardization Technical Committee, used bedside cabinets as an example to evaluate the changes in standards. The 1989 edition of GB/T10357 adopted European standards and other standards. After that, how much force should be added to the stability test of the partition and the drawer, and there is no detailed explanation, which led to the majority of the sampling inspection of a certain product, which led to the revision of the standard. “More realistic, more satisfied with the standard situation, more satisfied with the market situation, more scientific.†The reporter found that the new standard GB/T10357-2013 found that the series of standards includes a total of eight parts, including tables, chairs, cabinets, single-layer The mechanical properties of furniture such as beds are a common basic standard for testing methods. The mechanical properties are determined according to the consumer's use and carrying objects. No matter what kind of materials are used, it must be tested by the general technical standards of mechanics. In the eyes of the industry, the new standard is more "grounded" than the old standard. Take the GB/T 10357.4-2013 "Furniture Mechanical Performance Experiment Part 4: Cabinet Stability" as an example. The new standard is more in line with the actual production and inspection, and increases the general principle and center of gravity of the cabinet stability experiment. Determine the technical indicators such as the stability of the fixed cabinet, modify the stability test of the shelf, and clarify the strength of the experiment. For example, the vertical load stability test of the shelf requires that a vertical force of 100 N is applied downward at any point 25 mm away from the leading edge of the empty shelf that is most likely to cause the test piece to tip over, and whether the empty shelf is tipped over is recorded. The bedside table is using a scattered frame, the chair stool is sitting down, and the single-layer bed has not been used for a few years... From the previous news reports, the mechanical properties of the furniture is one of the main unqualified items of local and even national sampling. Enterprise production is also constantly adapting to changes in the market. “Market complaints, consumer issues, laboratory data, supervision and spot checks, and corporate feedback are the basis for standard revision.†Luo Jufen said that market complaint feedback is an important reference for the revision of GB/T10357. “There are some problems. The test found that the three problems of strength, durability and stability have appeared. There are many indicators involved, all kinds of products are involved, and the problems are not concentrated.†National furniture and indoor environment Sun Shudong, director of the Furniture Inspection Laboratory of the Quality Supervision and Inspection Center, said that the sampling inspection showed that the unsatisfactory mechanical properties of the furniture were not outstanding, but their importance should not be underestimated, because it is directly related to the safety of use. GB/T10357.4-2013 will be implemented in May next year, and there will be about half a year left. Will the new standard or some of its technical indicators pose a big challenge to the production enterprises? “No.†The opinions of industry experts are extremely consistent. Similar to Luo Jufen's view that “the big challenge that enterprises can't do†is, Sun Shudong believes that the technical content of the furniture industry is not too high, and whether the mechanical properties are up to standard, the key is to see whether some enterprises have produced according to the standard and whether they have cut corners. From the perspective of terminology and experimental methods, the mechanical properties are more professional and complicated. Then, as an ordinary consumer, how to identify the "passing" of the product's performance? Sun Shudong suggested that when consumers choose, they mainly rely on simple trials, smashing furniture, swaying, and showing signs of looseness and falling apart. "Or sit down and feel it. Just lean back or lean on it and judge it." In addition, the industry reminds that when choosing, you should pay attention to whether the proportion of furniture is coordinated, and try not to choose furniture with too long, wide and high proportions. Should pay attention to the furniture material, it is best to use solid wood, the thickness should match the function of use; finally pay attention to the design details, such as whether the design of the drawer slide is strong, and the inclination of the back of the chair is reasonable.
