1. Furniture testing is the main method to judge the quality and performance of furniture products and raw materials in accordance with national laws and regulations and relevant standards. The furniture inspection system is responsible for the important technical support responsibility in the evaluation of furniture product quality and safety, market supervision and product trade, and plays an important role in guaranteeing the quality and safety of furniture products and improving the overall level of the furniture industry. The furniture testing organization adopts scientific detection methods and sophisticated equipment to test the submitted inspection products to obtain accurate quality inspection results and feedback them to the company. In this way, the company separated unqualified products based on the test results, analyzed the quality problems, and proposed corrective measures. Through this inspection, feedback, and correction process, the company's product quality will be improved.

2. Current status of furniture testing China's furniture companies have gradually realized the importance of furniture testing, and the testing organizations in the society are constantly improving their testing standards and methods for the needs of companies. At present, the detection of furniture products by furniture inspection agencies mainly focuses on the four aspects of appearance inspection, mechanical property testing of furniture, physical and chemical property testing of furniture, and environmental performance testing.

(1) Appearance test: Visual inspection and ruler measurement are used for visual inspection and on-site inspection. Among them are functional dimensions, finishes, and coatings. Functional size must meet the requirements of use, to ensure that within the allowable tolerance range, if the functional size can not meet the requirements, the product is unqualified products, reducing the use of performance. Such as a large closet, when its dead-space depth is greater than 500mm, when the clothes hang horizontally in the cabinet, they cannot be squeezed after closing the door to avoid wrinkles.

(2) Inspection of mechanical properties of furniture: The test of mechanical properties is a test to simulate the strength or endurance of furniture under the conditions of one-time or repeated load when it is used normally and habitually used. According to the normal frequency of use of the product under the intended use conditions, the possible misuse intensity, according to the size of the loading force and how much the number of loading, the strength and durability are divided into five levels of test level, that is, the frequency of use determines the test level , Static load, durability and impact test of the product.

(3) Testing of physical and chemical properties of furniture: The test is mainly conducted on seven indicators, that is, the film is resistant to dry heat, moisture and heat, abrasion resistance, adhesion, gloss value, film thickness, and temperature difference between the film and the film. Among them, the film adhesion, wear resistance and temperature difference between cold and hot are particularly important. It determines the service life of the paint film on the surface of wooden furniture.

(4) Environmental performance test: It mainly tests free formaldehyde and soluble heavy metals in wooden furniture. The national standard stipulates three methods for the determination of formaldehyde content or release amount: perforated extraction method, desiccator method, climate chamber method (environmental test chamber method), and detection of soluble heavy metal elements to scrape appropriate coatings on the surface of furniture products. According to national standards, the soluble metal content in paints and varnishes was determined by atomic absorption spectrometry.

For the research related to the environmental performance testing of furniture, China started late in Europe and the United States. Since the 1980s, the United States and Europe have implemented strict environmental protection standards for furniture products. China's standards for formaldehyde and heavy metal content are mostly based on European and American countries. In spite of this, China's regulations on harmful substances in furniture and interior decoration materials have been aligned with developed countries and are in line with international standards.

Although China's furniture inspection system has begun to take shape and has made considerable progress, it is still necessary to constantly improve the quality of furniture products in order to catch up with European and American countries. First of all, the single detection criteria for furniture products and the backwardness of the standard system are the problems to be solved urgently in the furniture inspection system. On the one hand, the ultimate goal of the company's furniture inspection is to fully understand the product and improve product quality; on the other hand, consumers want to buy furniture that is comfortable, practical, and safe. So, the existing detection indicators and detection methods are far from the requirements of enterprises and consumers. Therefore, filling and improving the gaps and deficiencies in furniture inspection indicators is the direction of efforts made by furniture inspection agencies and researchers. Second, China's furniture testing equipment is not advanced enough. It is generally imported directly from abroad, and its independent research and development capabilities are not high. If the use of climate chamber method to detect formaldehyde, China's cabin is smaller. In comparison, the large cabin is close to the actual room, and can be tested for a whole piece of plate. The simulation is of a high degree and the measurement result is close to reality, but the cost is high and the operating cost is high. Small tanks can only perform small sample tests and the accuracy of the test is lower than that of the big tank. Advanced, high-end testing equipment is the guarantee of accurate detection results.
