GB Office Chair
The national standards related to 'GB office chairs' mainly cover aspects such as quality and dimension measurement. Here is a detailed introduction:
Quality Requirement Standards: GB/T 14531 - 2017 'Office Furniture - Reading Tables, Chairs, and Stools' is primarily applicable to furniture used in places such as libraries and archives, including office chairs. It sets clear requirements for the quality of office chairs, specifying corresponding test methods as well as packaging and storage requirements. Additionally, this standard introduces new test methods such as impact resistance and scratch resistance. The impact resistance test can verify the stability and structural integrity of office chairs when subjected to external forces, ensuring they do not easily break due to accidental collisions during use. The scratch resistance test evaluates the wear resistance of the office chair's surface, ensuring its appearance remains good under normal use conditions and extending its service life.
Dimension Measurement Standards: GB/T 38733 - 2020 specifies the dimension measurement methods for office chairs. This standard includes definitions of terms for various structural components of office chairs, clarifies the accuracy requirements for measuring equipment and facilities, and outlines corresponding test methods. It was released on April 28, 2020, and officially implemented on November 1, 2020, providing a unified standard for the accurate measurement of office chair dimensions, helping to ensure consistency and comparability in the dimensions of office chairs produced by different manufacturers.
Standards Under Revision: 'Office Furniture - Office Chairs - Dimension Measurement Methods' (under revision) is equivalent to the ISO international standard ISO 24496:2021 and is currently in the revision stage. This standard will also regulate the terminology of office chair structural components, measuring equipment, and test methods. It is under the jurisdiction of the National Furniture Standardization Technical Committee, with the competent authority being the China National Light Industry Council.
Seat Height Standard: GB3326 - 1997 specifies that the seat height should be between 400 and 440 millimeters. An appropriate seat height is crucial for the comfort and health of users. This standard range can meet the usage needs of most people, ensuring that users' legs are naturally relaxed when seated and reducing fatigue.
