Business office pressure chair standard lift
In 1996, China formulated the QB / T "swivel chair" standard for metal seats and formally implemented it on September 1, 1997. The standard provisions of the terms, classification, basic technical requirements of swivel chairs, inspection and test methods and other provisions. However, the widely used pressure chair lift is a product upgraded from screw-type swivel chair before and after 2000. The earliest production technology was introduced from foreign countries. However, the 1996 version of the standard did not stipulate the lifting pneumatic rod and other components and could not be targeted Sexual testing and testing.
In 2007, the National Development and Reform Commission released the QB / T "office chair" standard instead of the "swivel chair" standard and was officially implemented on March 1, 2008. The new standard has undergone major changes in name and scope of application. At the same time, many new requirements have been added, such as the dry rubbing fastness of leather, tearing strength, moisture permeability of textile fabrics, the limit of harmful substances of wood materials, Flame retardancy and so on. In mechanical properties, the standard combines both the actual use of office chairs in our country, but also try to keep track of advanced foreign standards. The new standard relative to the old standard more comprehensive and rigorous, is conducive to improving the quality of lift chairs and other products to ensure consumer safety. However, the provisions of the "office chair" standard for pneumatic rods (of "material requirements") are contract items, that is, pneumatic rods are not required unless the customer has a special contractual agreement when ordering the chair Inspection, test results also do not include this item. At the same time, the provisions of the pneumatic rod only refers to the JB / T 8064.1 "gas spring technical conditions" and JB / T 8064.2 "lockable gas spring technical requirements" in the durability requirements, design, production and other aspects of the link, and these two standards The latest version was released in 1996. Therefore, the "office chair" standard does not really solve the biggest safety hazard in lift chair - the problem of pneumatic rod. It can be said that the relevant standards of the domestic office chair left a blind spot in the air pressure lifting, leakage and safety hazards "space."
Relative to the domestic standard, foreign agencies in the office and home seating standards more comprehensive and rigorous. Such as the United States, "the general requirements of office chairs," "small office / home office furniture," and other standards, the European Union, "the security requirements of office chairs", "office chair security test methods", "office chair performance requirements and test specifications "And other standards. These standards provide a number of rigorous test methods and specifications, so products that meet these criteria tend to be of high quality. At the same time, many countries also set the certification system for such products, only meet the certification conditions, certified products can be imported and sold. Such as access to German office furniture generally through GS certification (safety certification), this certification is very strict, if the product fails to cause accidents, the manufacturer will be subject to strict German (European) "Product Safety Law," the constraints, which To ensure product safety is of great significance.
