Children's crawling mat is commonly used for children and infants and young children's sports toys, not only waterproof and moisture-proof, but also soft material to help prevent baby crawling, toddler may occur when the head, knee and other injuries caused by bright colors and Patterns also help to stimulate vision and brain development in infants and young children, and are therefore increasingly favored by parents and early education institutions.
Reporters found that the current market mats many brands, similar style, but the price difference between the disparity, so that ordinary consumers no choice. To understand the quality of crawling mats, recently, the Beijing Consumer Association on the market crawling Pad products were tested.It was tested that the mechanical and physical properties of 15 samples out of the 35 samples did not meet the relevant standards, the use of 10 samples showed problems, some samples had higher formamide content, and most of the samples were detected Volatile organic compounds pose a safety risk.
In response, Consumers Association to remind consumers to pay attention to the purchase of irritating odor, the best choice of tough and resistant to bending mats, the use of the process often check for damage, to prevent the production of small parts by children into the mouth.
Experimental samples
The sample of this comparative experiment, the Beijing Consumer Association staff to ordinary consumers from Beijing Jinyuan Lufthansa shop, Lotus (Jinyuan store), Beijing Wumart Huatian shop and other physical stores and Taobao, Jingdong, Amazon and other e-commerce platform to buy randomly, involving Beijing, Shandong, Zhejiang, Jiangsu, Guangdong, Fujian and other places to produce 32 brands of 35 kinds of crawl floor mats. The highest price of 692 yuan / unit, the lowest price 12.38 Yuan / piece, a difference of more than 50 times.
Experimental standards
The comparative experiment using the toy safety standards, all samples of the relevant performance testing and horizontal comparison.
Comparison of experimental samples entrusted Shenzhen British Park Detection Technology Co., Ltd., according to GB 6675.1-2014 "Toy Safety Part 1: Basic Specifications", GB 6675.2-2014 "Toy Safety Part 2: Mechanical and Physical Properties", GB 6675.3-2014 "Toy Safety Part 3: Flammability", GB 6675.4-2014 "Toy Safety Part 4: Specific Element Migration", SVHC Substances of Very High Concern of the REACH Regulation of the European Union, instructions on the purchased samples, Machinery and Physics Performance, Flammability, Specific Element Migration, Phthalates, Formamide and Total Volatile Organic Compounds were tested.
Experimental results 1: Low volatile organic compounds detected
The harmful substances test includes 'formamide' and 'total volatile organic compounds' .China has not yet made a mandatory standard for children's crawling mats, nor does it have any effect on formamide content and total volatile organic compounds in crawling mats Out of a clear requirement and limited, but the children crawling mats products in the production process will use a variety of chemicals, volatile hazardous substances has become an important topic of concern.
After testing, only 35 kinds of children crawling mat samples were not detected volatile organic compounds, the remaining 34 samples have varying degrees of volatile organic compounds were measured, the measured values were less than 19g / L, the domestic standard requirements similar limit of 50g / L.
Zhao Bin, associate professor of Chemistry and Chemical Engineering, Nanjing University, explains that volatile organic compounds mainly include harmful substances such as benzene, toluene and formaldehyde and have certain toxicity to human body. Children's climbing pad uses organic solvents in printing and dyeing processes, which often leads to fabric adsorption and the like There are organic residues.
Wu Hailu, deputy director of Consumer Association consumer guidance introduced in the past, sampling products, furniture more often measured such substances, especially plywood and other composite materials products are more common if the human body is long in this environment, will cause harm to health Fortunately, the values measured this time are lower than similar domestic standards, so the harm will not be that big.
Experimental results 2: formamide value of 9 samples exceeded
City Consumer Association introduced, formamide, also known as 'amino formaldehyde', was the EU REACH regulation as a SVHC (SVHC), was classified as a reproductive toxic substances by the European Chemicals Agency in the use of formamide in foam products can make Plastic foam, the greater the amount of formamide Plastic lighter, formamide can also increase the flexibility of plastic products, the product is not easy to break.
The volatility of formamide is a slow, long-term process. Usually children use mats in a relatively closed environment. As a result, the slowly released formamide in children's floor mats continuously penetrates children's bodies through the respiratory tract and skin.
The comparative experiment with reference to the EU REACH regulations for the highly concerned substances in the relevant requirements of formamide samples tested REACH regulation of substances of concern for formamide requirements limit 1000mg / kg EU Toy Safety Directive for formamide restrictions May 24 this year, the implementation of foam toy materials required for formamide in the content of not more than 200mg / kg, or need to be released for 28 days of testing, and the amount of formamide release should not exceed 20μg / m3. Taiwan, China For The demand for formamide in children's splicing mats is limited to 200mg / kg.
After testing, 22 samples were tested for formamide, 9 samples of the measured value of more than 200mg / kg, of which 3 splicing crawling mats samples measured more than 1000mg / kg.
Experimental results 3 easy to shedding small parts is not clearly warning
Children 3 years of age and below have a strong preference for stuffing things in and therefore children's toys in this age range are prohibited from containing small parts while children over the age of 3 do not often stuff non-food objects , But there is still a certain possibility, so the standard allows children in this age group there are small parts of toys, but caution must be marked to remind guardian attention; In addition, the average thickness of plastic bags, such as packaging is too thin, easy to adhere to children's nose and mouth, there Cause the risk of suffocation.
After testing, 35 kinds of children's crawling mat sample of 15 kinds of samples of mechanical and physical properties do not meet the standard requirements, mainly in the detachable or easy to fall off small parts, some products contain small parts but no warning or warning Does not meet the standard requirements, the average thickness of plastic bags is less than 0.038mm (standard), the toy bag sealing method, the ring circumference does not meet the requirements, etc. Mat corners, zipper head pull under the provisions of the pull, resulting in small parts, Such as accidentally being put in the mouth may cause infantile suffocation, causing a safety accident.
Hint: Do not buy products that contain irritating odors
City Consumer Association introduced, at present, there is no corresponding mainland China specifically for children's crawling mats product standards, most of the products on the market using toy safety standards or their own corporate standards as the implementation of standards.Recommended departments to develop children crawling Mat the relevant standards, especially for physical indicators involving infants and young children and adolescents, formamide, volatile targets strictly limited to regulate the mat production enterprises, so that consumers feel comfortable buying, ease of use.
Consumers Association to remind consumers to select children's crawling mats, should pay attention to see the instructions (logo) information, including product name, age range, safety alerts, producers, distributors, name and address, Three non-product '.
Buy attention to the presence of irritating odor, such as opening the outer package can smell pungent taste, do not buy.Child crawling mats in the production process to use a variety of chemicals, such as a harmful chemical substances exceeded, Will cause harm to the human body.
In addition, the best choice of texture is more tenacity and bending of the mats, the use of the process should always check for damage, to prevent the existence of small parts there is a security risk.You should also save the voucher for quality problems in order to effectively maintain their own The legitimate rights and interests.
