On August 1, the "General Technical Conditions for Children's Furniture" will be officially implemented. Because the new "national standard" is China's first mandatory national standard for children's furniture , it has received widespread attention in the industry.
It is only 5 days away from the official implementation of the new regulations. However, the reporter found that from October 2009 to the present, there have been many "children's furniture recalls" at IKEA in many places around the world, and some of the children's furniture products on sale are different from the above new regulations.
After entering the children's furniture area of ​​IKEA Shanghai Xuhui store, the reporter saw a desk named "Mick" with a price of 699 yuan, which was sharp at both the edge and the tip. The "Shufat" storage rack with a price of 599 yuan also has the above situation in various products including desks and beds .
According to the new "national standard" for children's furniture, furniture products designed or intended for children aged 3-14 are children's furniture. Dangerous sharp edges and tips refer to the edges and tips that can be injured, dangerous, and accessible during use.
The new "National Standard" Article 5 "Safety Requirements" stipulates that products should not have dangerous sharp edges and dangerous sharp tips, and edges and edges should be rounded or chamfered. The product can reach the dangerous outer corner at a height below 1600mm from the ground and should be rounded, and the rounding radius is not less than 10mm, or the rounding arc length is not less than 15mm.
Yin Lifang, a spokesman for the quality of IKEA's household products, told reporters that the current IKEA children's furniture products do not comply with the new standards. The current IKEA products do not comply with the new regulations mainly on the rounding of the cutting-edge furniture. Previously, since October 2009, IKEA has recalled children's furniture products many times.
Yin Lifang said that from August 1st, IKEA will install anti-collision corners for the products that do not meet the new regulations at the tip of these furniture. .
However, Xiong Xiaokun, a light industry researcher at CIC Consulting, told reporters that from the actual reflection, the installation of anti-collision angles and the rounding process are essentially different. Although the starting point is to prevent collisions and other accidents during the use of children, the installation of anti-collision angles does not solve the fundamental problem. After the anti-collision angle is installed, if a child collides during use, it will still cause a great hidden danger to the child's personal safety. It only plays a preventive role.
The reporter called the Supervision Office of the Shanghai Quality Supervision Bureau. Staff Mr. Shen said that the "national standard" is different from industry standards and can be said to be the bottom line standard for measuring product quality. If after testing, it does violate the "national standard", it means that it violates the national standardization law and product quality law, which is a product that is unqualified, substandard, and violates health standards. Mr. Shen said that if the furniture brand does not meet the standard from August 1, then the company will be dealt with and punished, and the punishment standard will be determined according to the specific circumstances.
Heat Treated Steel Bar And Tube
Heat treated steel bar is produced by heating and cooling in different temperature based on the steel grades to improve the steel bar mechanical properties or machinability for various industrial applications. Heat treated steel bar includes annealed steel bars, Normalized Steel Bar, quenched and temper qt steel bar.
Annealed Steel Bar has better ductility and lower hardness, which can be easier to be machined. The annealing processing is usually widely used for steel grade with higher carbon content above 0.5%. However, some low carbon steel also requires to do annealing for special usage such as 20CrMnTi gear steel. For some special material such as 20CrMnTi gear steel and GCr15 such bearing steel, spheroidizing annealing is often required.
Normalized steel bar sometime is also one kind of annealing processing. It mainly changes the grain to remove the impurities in steel and improves the strength and hardness. For some hot rolled steel bars, to keep the basic mechanical properties, normalizing is often used.
Quenching and Tempering, abbreviated as Q&T is a king of processing that strengthen or harden steel bars by heating the materials and then cooling in water, oil or other liquid medium, that rapidly the change from austenite to perlite to get the proper properties for various usage. The quenched & tempered steel bar materials are usually with carbon from 0.30% - 0.60%, it is widely used as merchant bars in components of various machines.
Our advantages on producing heat treated steel bars:
1) Big stocks of hot rolled round bars or wire rods as raw materials
2) Wide range of Cold Drawn Steel Bar sizes: from 10mm to 150mm
3) Different cold drawing medias powder or oil to get different surface
4) Straightening machines to get better straightness up to 0.5mm/m
5) Grinding and polishing machines to get better roughness upto 0.4um
6) Heat treating furnaces to adjust the mechanical properties
7) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.
8) Multiple packages to avoid broken packages and anti-rusty
