1 Scope

GB/T 26463-2011 is the Chinese national standard on oxo s ynthetic fatty alcohol, in the field of chemical technology. 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 12 May 2011 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 15 September 2011. Classification: ICS 71.080.60, CCS G17. 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 oxo alcohols product classifications, requirements, test methods, inspection rules and signs, packaging, transportation and storage. This standard applies to medium pressure Oxo alcohols production.
