Standardization of Spring in China
Standardisation was established and started in 2000 as an international organisation. Under the leadership and organization of National Technical Committee for Spring Standardization, 40 standards for springs and spring products (Table 1-6) have been completed, and a system has been initially formed. In addition, the followings are under preparation for approval: rubber-metal spiral composite spring, fatigue test outline of spring, etc.
