LS/T 1707.3-2017Classification and codes of grain information. Grain storage. Part 3: Classification and codes of material and equipment (English PDF)

Foreword

LS/T 1707 "Food Information Classification and Coding Grain Storage" is divided into three parts.

--- Part 1. Classification and code of warehouse operations;

--- Part 2. Classification and code of food situation detection;

--- Part 3. Equipment classification and code.

This part is the third part of LS/T 1707.

This part is drafted in accordance with the rules given in GB/T 1.1-2009.

This section replaces LS/T 1707.3-2004. The main technical changes compared with LS/T 1707.3-2004 are as follows.

--- Removed the "sealing material thickness" that is not part of the original standard;

--- According to the current national grain industry management regulations, the addition of "self-contained air breathing apparatus";

--- Added "closed equipment", "lighting equipment", "walking board", "boots", "sample bucket" and grease storage and other related equipment.

This part is based on GB/T.20001.3-2015 "Standard writing rules Part 3. Classification standards", GB/T 7027-2002 "Information the basic principles and methods of classification and coding, combined with the main storage equipment in the grain storage enterprises to give a comprehensive code.

This part is proposed by the National Grain Bureau.

This part is under the jurisdiction of the National Grain and Oil Standardization Technical Committee (SAC/TC270).

This section drafted by. Henan University of Technology, National Grain and Oil Information Center.
