1 Scope

GB/T 13828-2009 is the Chinese national standard on stranded wire cylindrical helical springs, in the field of mechanical systems and components. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 16 March 2009 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 November 2009. Classification: ICS 21.160, CCS J26. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the multi-strand cylindrical helical compression springs, tension springs, torsion spring design calculations, technical requirements, test methods and inspection rule. This standard applies to more ordinary shares of cylindrical spiral compression, tension and torsion springs (hereinafter referred to as spring).
