For the first time, the new standard clearly defines the limits and limits of hazardous substances, which will change the formaldehyde emission of excessive soft furniture in the past, abnormal smell or fabric containing harmful dyes, but no standard can be used, resulting in undetectable embarrassing situation, and also for future software in China. Furniture exports are supported by technical barriers in other countries. Old standard constraint range is too small The commonly used soft furniture includes sofas and mattresses, mostly made of wood materials, metal, etc., with springs, bandages, etc. as load-bearing materials, and the surface is covered with fabric. The reporter learned that soft furniture belongs to a kind of wooden furniture. The current national GB 18584-2001 "Restriction of Hazardous Substances in Wood Furniture for Interior Decoration Materials" only refers to the amount of formaldehyde released in the furniture and the heavy metal in the paint. The content of lead, mercury, cadmium, etc. is specified, and the harmful substances contained in the upholstered furniture are not described. For the above reasons, many of the current soft furniture manufacturers are qualified to use formaldehyde as the basis for environmental protection, and are harmful to TVOC (total volatile organic compounds) and azo dyes (decomposable aromatic amines) contained in soft furniture. Material lacks control basis. When a consumer encounters a problem complaint, the testing organization and relevant departments can't do anything because they have no basis to follow. Zhu Changling, chairman of the China Furniture Association, said that setting standards as soon as possible to supplement and improve the testing and testing methods of hazardous substances is the key to solving the environmental problems of soft furniture consumption. The new standard clearly defines and limits hazardous substances for the first time. Among the four new standards that have been approved, the Limits of Hazardous Substances in Upholstered Furniture Mattresses, the Limits of Hazardous Substances in Upholstered Furniture Sofas, and the Determination of the Content of Dimethyl Fumarate in Furniture as National Standards Enforced by Technical Indicators For the first time, the complete products for soft furniture sofas and mattresses have made clear provisions on the selection of raw and auxiliary materials, production processes and hazardous substances, and provided safety guidance for consumers to purchase soft furniture. It is understood that the limited amount of harmful substances in the standard of soft furniture is mainly caused by direct damage to the health of the product when the product is used, and the environmental impact after the end of use. Luo Wei, deputy director of the National Furniture and Indoor Environmental Quality Supervision and Inspection Center, said that the new standard has set limits for formaldehyde, TVOC and serious carcinogenic azo dyes present in fabrics. As specified in the standard: a square meter of mattress in a cubic meter of flowing air, formaldehyde emission should be less than 0.1 mg. In a cubic meter sofa, the amount of formaldehyde released must be less than 0.05 mg. At the same time, the selection of the corresponding harmful substances in the "Limits of Hazardous Substances in Soft Furniture Mattresses" has also increased compared with sofa products. Due to the sensitive odor and odor of the soft mattress of the spring, long-term exposure to such abnormal odor during sleep with the weakest resistance of the human body may reduce the quality of sleep, which may cause discomfort, insomnia, and nausea. In addition, the fabrics with flame retardant properties of mattresses are increased, and some flame retardants are also harmful to the human body. Therefore, the standards also use five kinds of flame retardant finishings banned in the "Technical Requirements for Ecological Textiles GB/T 18885-2009". Agent. Improve testing methods to maintain consumer safety Anyone who has encountered environmental problems with soft furniture knows that consumers have been in a passive position. It is understood that the current detection methods for wood furniture cannot completely and accurately determine the amount of harmful substances released from soft furniture. This detection loophole also poses a great hidden danger for the furniture industry and the market. The “Crystal Chamber Inspection†adopted by the new standard effectively compensates for this problem. The scope of its inspection is more extensive. For the part that could not be started, the corresponding results can be obtained through comprehensive testing. Whether the soft furniture contains wood, steel or sponge. As long as there is a material that is not environmentally friendly, it can be concentrated in the comprehensive test results. Previously destructive testing methods themselves caused damage to furniture. According to reports, the four software furniture standards will also replace the damage detection with non-destructive testing. The “climate box inspection†will place the whole piece of furniture in a specific environment for testing, and the furniture itself will never be damaged to any degree. Luo Wei said that the cost of testing with the new method has also increased, about 3-4 times the original, but the damage detection is replaced by non-destructive testing, which saves the cost of the production enterprise and also provides convenience for consumers. If the test results are ok, the consumer can take it home and continue to use it. â– Standard interpretation 4 criteria The four software furniture standards are “Limited Hazardous Substances in Soft Furniture Mattressesâ€, “Limited Hazardous Substances in Upholstered Furniture Sofasâ€, “Determination of Dimethyl Fumarate Content in Furniture†and “Soft Furniture Sofasâ€. The first three are national standards for technical indicators (non-mandatory testing methods), and the "soft furniture sofa" is a light industry standard. It is a revision of QB/T1952.1-2003 "Software Furniture Sofa". Violation of anti-mold agents will be limited As a mold inhibitor, dimethyl fumarate is only used in furniture export packaging. Since 2008, the use of dimethyl fumarate in China's export furniture products has caused incidents of skin allergies and pimples in consumers. It has seriously affected the export of China's furniture products, especially leather sofas and fabric sofa products. "Determination of dimethyl fumarate content in furniture" is the first specific method for the detection of such harmful substances in furniture products at home and abroad. The determination of its content has detailed provisions, which will ensure the quality and safety of China's furniture products. Free from technical barriers set up in other countries in export trade. Standards increase material selection and performance strength requirements According to Luo Wei, deputy director of the National Furniture and Indoor Environmental Quality Supervision and Inspection Center, the revision of the industry standard for "soft furniture sofas" is mainly to increase the requirements on fabrics. In the method of detecting color fastness, dry friction The method was changed to the latest washing method and perspiration method. At the same time, in terms of mechanical properties, the requirements for safety moving parts have been increased, and the positional fixing of sofa products has been regulated. â– Consumer guidance Purchase first look at the product inspection report â—Liu Xianming, General Manager of Gujia Craft Sofa Beijing When selecting a sofa product, first pay attention to the description of each indicator in the product manual, or specify the material, sample color number, etc. in the purchase contract, and also ask the salesperson to produce the inspection report of the product. For the harmful substances above the standard requirements, some intuitive methods can also be used. For example, aromatic hydrocarbons have a pungent aroma, and excessive formaldehyde emission may have the feeling of smoking eyes or tearing. Filling may cause excessive â—裴è£æ—, Marketing Manager, Xilinmen North Furniture Co., Ltd. When purchasing a mattress, pay attention to the strength of the spring, the material to be filled, and the fabric. In addition to the properties of the spring, whether the mattress product meets safety standards depends first on the filling of the mattress. The use of some chemical and textile raw materials for mattress fillers is not tight enough, which may cause harmful substances to exceed the standard. Therefore, the sales personnel should be asked what materials are filled. The choice of fabrics is mainly concerned with the comfort and breathability of human contact, and it is generally judged by the intuitive experience whether it is suitable for consumers. Lie down and touch the fabric with your arm to feel the comfort of the fabric.
