This is Part 3 GB 18071's.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This Part replaces GB 11663-1989 "from the sulfuric acid plant health protection standards." Compared with GB 11663-1989 portion of the main changes are as follows.

--- Adjust the standard name, and according to GB/T 1.1-2009 "Standardization Guide Part 1. Standard structure and drafting" Adjust the structure of the standard;

--- Amendments to the definition of health protection distance, increasing the sensitive area, complex terrain two terms and definitions;

--- Revised the Health protection zone standard limits, established a production scale sub-file;

--- Increased requirements for greening.
