As early as 2007, the National Development and Reform Commission issued the QB/T2280-2007 "office chair" standard, which was implemented on March 1, 2008. The standard is the dry rubbing color fastness, tear strength, and textile of the chair leather. There are strict requirements on the moisture permeability of fabrics, the limit of harmful substances in wooden materials, and the flame retardancy. However, the provisions of gas springs in the [Material Requirements" are contract items unless consumers order special chairs. The contract stipulates that otherwise it is not necessary to test this, and the judgment of the test result does not include this item.
For gas springs, the country has also issued relevant national standards, namely GB/T25750-2010 "Technical Conditions for Lockable Gas Springs" and GB/T25751-2010 "Technical Conditions for Compressed Gas Springs". According to Jiang Yan, secretary general of the National Spring Standardization Technical Committee, the seat lift gas spring is one of the lockable gas springs, which is used to adjust the height of the seat. With the increase in demand for products, the improvement of production technology, and the competition in the market, it is also considered that the seat lift gas springs must withstand the special requirements of lateral impact and rotational force of the seat, plus the existing safety hazards, the national spring standardization technology. In 2010, the committee applied for the National Standard Development Plan for the Technical Conditions of Seat Lifting and Air Springs. At present, the standard has been drafted and passed the relevant review. It has been submitted to the relevant departments in accordance with the procedures and is expected to be introduced next year.
