The safety of the gas bar of the office chair mainly depends on the quality and safety measures of the gas bar. The national standard requires effective isolation between the pressure bar and the seat surface, and the thickness of the explosion-proof isolation plate cannot be less than two millimeters. The purity of nitrogen inside the pressure rod must reach more than 90%, and the thickness of the tube wall must be controlled between 38-45cm. The wall thickness of the big brands of pressure rods usually exceeds the international standard, reaching more than 2.5mm.
Safety measures and common problems of office chair air rod
In order to ensure the safety of the gas rod, some brands have installed an explosion-proof steel plate about 3mm thick between the pressure rod and the base. However, in order to reduce costs, some businesses may use thin, poorly made pressure rods, or even replace pure nitrogen with other substances, resulting in a “loss of pressure” and an increased risk of explosion. In addition, a substandard air pressure bar may cause the seat to explode during use, causing injury to the user.
Recommended purchase
In the purchase of office chairs, should pay attention to the following points:
Choose SGS, BIFMA, TUV and other authoritative certification of air pressure rod , the higher the strength level, the better the safety.
Check that the tube wall thickness of the pressure bar should be at least 2mm.
Avoid buying products that are priced too low because low prices often mean compromises in materials and workmanship.
Choose products of big brands , because big brands are more guaranteed in terms of product quality and safety.
Through the above measures, can effectively reduce the safety risk of office chair gas rod.
