1 Scope

GB/T 13659-2008 is the Chinese national standard on 001×7 strong acid polystyrene cation exchange resin, in the field of rubber and plastic industries. 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 30 June 2008 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 February 2009. Classification: ICS 83.080.01, CCS G32. 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 001 × 7 strong acidic styrene cation exchange resin of the technical requirements, test methods, inspection rules and signs, including Loading, transportation and storage requirements. This standard applies to the 001 × 7 strong acidic styrene cation containing a sulfonic acid group-exchange resins.
