Foreword

GB/T 12529 "Graphic Symbols and Codes for Grain and Oil Industry" is divided into five parts.

--- Part 1. General part;

--- Part 2. Rice milling industry;

--- Part 3. Milling industry;

--- Part 4. Oil industry;

--- Part 5. Warehousing industry. This part is the fifth part of GB/T 12529. This part replaces GB/T 12529.5-1990 "Graphic symbols for grain and oil industry, code storage industry". The main technical differences between this part and GB/T 12529.5-1990 are as follows:

1 Scope

GB/T 12529.5-2010 is the Chinese national standard on graphic symbols and codes for grain and oil industry - part 5: storing and handling, in the field of food 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 26 September 2010 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 March 2011.

The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This part of GB/T 12529 specifies the graphical symbols and codes for grain and oil storage equipment. This section applies to the process flow chart in the field of grain and oil storage and other related fields. This section does not specify items that are not generally expressed in the process flow diagram and those that have been included in GB/T 12529.1.
